There are lots of interesting things living in the sea. Here is some information about Minuscule Sea Animals, Sea invertebrates, Sea Reptiles, Sea Mammals, Sea birds and other sea creatures.
Minuscule Sea Animals
Zooplanktons are the very small animals in the ocean biome - which mainly include of small crustaceans and fish larvae. Some examples of zooplanktons are protozoa, chaetognaths, mollusks, arthropods, annelids etc. There are 500 types of zooplankton animals recorded in the Sargasso Sea in the North Atlantic Ocean alone, whereas the total number of Zooplanktons in the entire world is expected to be more than a million.
Sea Invertebrates
Jellyfish, Octopus, Crab, these are sea animals which are usually distinguished by the absence of a vertebral column. These types of invertebrates are generally found in the surrounding area of coral reefs and these also referred to as coral reef animals. Examples of invertebrates in the marine biome include jelly fish, deep sea worms, shellfish, squid, octopus, star fish, crabs etc. As in the case of different land biomes, invertebrates make up an important portion of living organisms in water biomes.
Fish Species
There are more than 31,500 variety of fishes are there in various oceans of the world. These fish species range from microscopic fat infant fish to large whale sharks. Examples of well know fish species of the world include sardines, halibut, sharks etc.
Sea Reptiles
Sea Reptiles includes different types of sea snakes, sea turtles, and also some types which common between sea and ground such as the sea iguana and saltwater crocodiles. Most of the seas reptiles are found in the oceans are oviparous that is animals which put down eggs, with sea snakes being the only exception. Due to their tendency to come on land regularly, these reptile species are most frequently seen in low waters close to land. Although sea snakes rarely come on land, they do prefer shallow waters of estuaries particularly wherein they can get protection from their predators.
Sea Mammals
Dolphins and blue whales these are the two names that's comes to your mind when we talk about sea mammals. Apart from these animals, Sea mammals include seals, sea otters and other types of whales include gray whale and humpback whale. In marine mammals list, Polar bears strictly don't be eligible because due to the key role they take part in in marine ecosystem in polar areas.
Seabirds
Seabirds are also called as marine birds. Seabirds differ very much in lifestyle, behavior and physiology. Some of the well known seabirds include penguins, albatross, seagulls, etc. These seabirds are also popular for their traveling habits.
That was short information about sea animals which have an important share when it comes to the biodiversity of earth.

Facts From the Shark Cage: How Big Is the Great White Shark?
Great white sharks are some of the most infamous inhabitants of the ocean. They are portrayed in folklore and Hollywood as giants of prehistoric proportions. This has left many people wondering, out of curiosity and/or fear, how big these marine leviathans really are.
While many young land animals (including humans) are born as cute, awkwardly proportioned examples of their species, the white shark comes into the world as a perfectly proportioned miniature replica of the adult it will become. Pregnant female whites have been caught with pups inside measuring 2.5 -3 feet long, and the smallest sharks found in fishing nets have been around 4.5 feet. This has led many to believe that whites are born at a length of 4-5 feet.
An adult white shark is typically between 13 and 17 feet long and weighs 1,500-2,500 pounds. Like most other shark species, the females are most often larger than the males. A fully mature female averages 15-16 feet long, and mature males average 12-14 feet.
Anyone who is a fan of the movie Jaws, recalls Quint the shark hunter stating with certainty that the monster shark terrorizing the waters near Amity Island was 25 feet long. Can these sharks really get that big?
Game fishers and shark hunters for over a century have reported seeing/catching white sharks over 20 feet long, but almost all of these claims have been either unconfirmed or later disproven. As any fisherman will tell you, it is not uncommon to overestimate the size of a prized catch - due to prideful exaggeration and wishful thinking. Scientists and shark experts use the teeth and jaws of these deceased animals to retroactively estimate the actual size of "record breaking sharks," and almost always find them to be several feet shorter than advertised. This is often also true when "official measurements" of the shark at the docks differ from the initial claims of the proud angler who landed it. More than a few indignant shark fishermen believe the theory that a dead fish shrinks after a period of time out of water, and that their great white trophy had gotten considerably smaller between the time it was caught and the time that someone official had gotten around to measuring it!
Some of those record-length white sharks weighed well over 3,000 pounds, yet even this is a source of controversy and debate. Great whites have been caught with several hundred pounds of meat in their stomachs. Scientists and fisherman still argue amongst themselves as to whether or not the final recorded weight of the shark should include stomach contents.

Importance of Sea Turtles to Humans
Sea turtles have been living on this planet named Earth for more than 100 million years and they have travelled throughout the oceans of the world. They are one of the oldest species living on the earth. Their body structure is so much well designed that they have even survived the extinction which the dinosaurs failed to survive. But now human beings have become the greatest threat for the survival of this mighty creature. We have destroyed the harmony of nature and environment in such a way that sea turtles who have survived great extinctions are now on the brink of getting extinct. We can learn about the present condition of the earth's climate and environment by observing the present condition of the sea turtles.
Sea turtles are of great economic value. They are the assets of those countries who have them in their territory. Sea beaches are popular tourists spot. Every year lots of people travel throughout the beaches of the world. And the beauty of the sea beaches is its living beings. Without corals, fishes, turtles and other estuarine animals, sea beaches lose its beauty. And to keep the ecosystem of the sea working in a proper way, all living beings should be conserved.
Green sea turtles are usually herbivorous in nature. They eat sea weds and keep them short which helps to maintain the quality of the sea bed. Sea grass also needed to be cut short like lawn grass for its better growth. Sea beds provide the ground for breeding for many valuable sea animals like crustaceans, fish, shellfishes etc. If turtles get extinct, health of the sea bed will be deteriorated and sea grass will decline. As a result, animals living on grass will be lost and this will affect other big animals who live on small herbivorous animals. Eventually whole ecosystem will collapse resulting in the destruction of the living beings of the sea which is the source of beauty of the sea beaches. So tourists would not come to travel sea beaches and the countries whose economies depend on tourism will suffer in the long run.
Sea beaches and dune system can not hold nutrition. So vegetation does not grow well in dunes and in beaches it does not grow at all. Sea turtles nest and lay eggs on beaches. Each turtle lays almost 100 eggs each season. Not every egg would hatch and not each of the hatchlings would be able to come out of the eggs. All these unhatched eggs and hatchlings who do not become successful in coming out of the nest and make the way to the sea are the source of nutrition in the beaches and dunes.
The more the nutrition the more vegetation grows in dunes. And as more vegetation grows, ecosystem of the beaches and dunes works properly. The vegetation also grabs the sands firmly in the beaches and prevents from being eroded. This saves the beauty of the sea beach. As the number of sea turtles is decreasing day by day, nutrition sources of dunes and beaches are also decreasing as a consequence. This will lead to the failure of the whole ecosystem and as a result the beach will lose its appeal to the tourists which will affect the economy of these countries severely.
Sea turtles have historical importance too. They were the symbol of aristocracy and delicacy in the ancient time. In China and Japan tortoise shell were used as a decorative ornament. They used to make it from carapace scutes of tortoise shell. Sea turtle scutes were processed by ancient Greeks and Romans to make components like brush and combs. Aristocrat class people used these tortoise produced components.
Peru's ancient inhabits Moche used to worship the sea and living beings of the sea. Sea turtles have often been highlighted on their arts.
Mexican people harvest sea turtles for food and boot. In many areas of the world coastal people depend on turtles for the source of protein. Their skin is used for making shoes and leather bags in many areas of the world. They also protect humans from the attack of deadly box jellyfish by eating them.
We can see that the world is becoming a hostile place for sea turtles. It is a clear warning to us that it might become harder for us to survive too. If we learn from the mistakes which we have made and pledge to make things right to save sea turtles from getting extinct, we will be saving ourselves too.

8 Uncommon Species of Fish in the Deep Sea
Coelacanth
The coelacanth is a lengthy fish; weight of coelacanth fish is an average of 176 lb. (80 kg) and length is as long as 6.5 ft. (2 m). By investigating their ear bones, scientists know that coelocanths are long living fish -some coelacanth living as long as 80 to 100 years. There is an African type, which is deep blue in color to help it camouflage, and an Indonesian type, which is brown in color. Coelacanths have very sensitive eyes and only go out to chase at night. The rest of the day, they rest deep sea water column, dwelling at depths of up to 2,300 ft. (700 m) underwater, while they typically stay at about 295 to 656 feet (90 to 200 m). Coelacanths hunting snipe eels, cuttlefish, squid, small sharks, and other fish.
Borna Snakehead
Borna Snakehead is a very rare fresh water fish. It is also known as the Chel Snakehead. It is a part of the Channidae family. The length of Borna Snakehead is from 20 to 25 centimeters and it can be found in a single area in northern Bengal, India. Borna Snakehead sometimes called the "Frankenfish," the snakehead is a big killer that eats fish, amphibians, crustaceans, birds, small reptiles, and even small mammals.
Megamouth Shark
The megamouth is a large shark. Full-grown adults are at least 5.5 m in length and 800 kg in weight. Megamouth Shark has a very large, wide head, small eyes and five pairs of gill slits. The back is grey to grey/black color and the underside is white color. Megamouth Shark is very large animal. It eats jellyfish and plankton. This shark is rather like the Whale Shark and Basking Shark in the sense that it uses its large mouth to filter feed.
Goblin Shark
Goblin Shark is also known as "Mitsukurina Owstoni". It is another rare deep sea shark and can be found in the area of South Africa, Japan, Australia and the United States at depths in the range of 200 - 500 meters.

Looking After Fish - Getting Work As an Aquarist in a Public Aquarium
Working as an aquarist at a public aquarium can be a very rewarding career. Not only do you get to learn and look after many varied species of animals related to the underwater world, but you can also contribute to research and our understanding of some amazing animals.
On any given day, you may be asked to clean aquarium tanks, prepare food for the animals, dive and feed large sharks and rays, deliver public presentations and go out on collections for new animals to be put on display. You may even get the chance to be involved in learning the best way to keep animals that no one has been able to keep in captivity before. It's a job that is fascinating and requires knowledge across a range of disciplines... but that's what makes it so interesting. You'll get to hang out with animals that have their own personalities and that is one of the most rewarding parts of the job.
But it can be a difficult industry to break into. There are few jobs and those there are, are often tightly held. That doesn't mean it's impossible though. There are some steps you can take to help you get your foot in the door.
1. Get a degree. Anything ocean related is good but some useful subjects include marine biology, oceanography, zoology, even vet science with some field experience can help.
2. Learn to scuba dive. Looking after fish in a public aquarium will involve diving. Large tanks will need to be cleaned and animals will need to be fed. Go diving - a lot. You will need to be comfortable in the water. A large display with sharks and rays can be an unpredictable place and you'll need to be able to deal with any situation that might come up.
3. Volunteer anywhere you can. It doesn't need to be an aquarium but somewhere ocean related is good. There's always small educational or research organisations that are always looking for help. But the trick is to be consistent and committed. Treat these volunteer positions like a job - they very well might lead to one.
4. Apply for an internship. Many Aquariums offer programs where you can learn on the job.
5. Take up underwater photography. This in itself won't get you a job but it's a skill that's useful as often sharks and fish are identified by their markings and good photos are valuable.
6. Be comfortable talking to large groups of people. Aquariums need to make money and sometimes you may be the attraction. People are always interested in hearing about what an aquarist does.
7. Be prepared to start at the bottom. Sometimes that might mean cutting up fish food and cleaning the floors but it's a foot in the door and if you impress it won't take long to move up.
Working in a public aquarium as an aquarist requires commitment. It's a job that isn't going to make you rich but it will provide you with experiences that you won't get anywhere else. If you love the ocean and the animals that live there, this could be the job for you.

Learn Some Interesting Facts About Crocodiles
Crocodiles are reptiles from the family of crocodilians, which actually also includes, the alligators, caimans and the Indian Gharial. Crocodiles are generally traced back to the Cretaceous as well as the Triassic period. Crocodilians, in general, are animals of elongated body as well as a long tail, lengthy jaws through which they show a great number of sharp conical teeth (typically 28 to 32 teeth in the top jaw and 30-40 teeth in lower jaw). In crocodiles, the muzzle is narrower in the end, with the 4th tooth on both sides of the lower jaw exposed when the mouth closes.
The crocodiles are semi-aquatic creatures (they will spend a great deal of time in water, but additionally require go to shore for basking) who, depending on species, will be found in rivers, estuaries, coastal regions as well as in the open sea. They swim, frequently on the surface with eyes as well as nostrils along the water line and move their own body using the strong tail.
The Crocodiles are carnivores, and among them, are large hunters such as the Nile Crocodile as well as the Saltwater crocodile. The saltwater crocodile is definitely the biggest reptile in existence, because it may well attain seven meters long and more than 1 tonne (1000 kg) in weight.
As young they feed on smaller animals (insects, fish, frogs), but as they get bigger they begin hunting animals ever bigger, until the size of a big antelope.
Just like the other reptiles, crocodiles are endothermic (cold-blooded, or whose body temperature varies with the temperature of the environment) and, as a result, need to sunbathe, to raise the temperature of the body. If it is overheating, they would prefer water or shade when available.
Crocodiles are oviparous (they reproduce using eggs which are deposited outside of the female's womb) and are the only reptiles that show true parental care. Therefore, almost all the crocodiles construct nests, by using heaps of dirt or plant debris, the remaining species of crocodiles dig burrows on the sand banks of rivers as well as beaches. Females, in general, and occasionally the male remains nearby to guard the eggs from predators.
Before the hatching, the young will emit vocalizations (sounds), to which the female responds simply by scooping the top of the nest, to help them out the eggs after which it will occasionally hold the young in her mouth and take them to the water, protecting them subsequently in certain cases during weeks or months. Upon birth the juvenile will measure only approximately 20 centimeters.
Man is an important enemy for all crocodile species through their hunt for the skin trade, in addition to the devastation of their natural habitat.
Crocodiles are truly breathtaking creatures, that in fact play a vital role in their Eco-systems. Therefore they should be protected and saved. We must discover how to live in the crocodile world as they have lived on this planet for the preceding 2 hundred million years, and that's much longer than mankind.

Infrared Wildlife Cameras - Trail Cameras Give a Fascinating Insight Into Wildlife Activity
Infra Red Wildlife trail cameras can provide a fascinating insight into the nocturnal and daytime movements of elusive species such as otter, deer, foxes and red squirrels.
Infrared trail cameras are essentially mobile digital cameras which have a motion detection system that detects a human or animal intruder into an area, and triggers a camera which takes either a series of still images, or video footage.
Primarily designed for hunters to scout deer patterns in a hunting zone, these cameras are now more and more used for wildlife observation.
BBC Countryfile recently featured their Stealth Cam Prowler HD infra red scouting camera, showing how they can be used to great effect to capture footage of elusive animals such as river otters and badgers.
The RHS Chelsea Flower Show coverage on BBC also recommends the use of these infra red cameras for people looking to see who or what is lurking around their garden at night, and suggested they are particularly useful for capturing footage of the nocturnal movements of the badger.
Infrared and incandescent wildlife cameras
Some trail cameras are equipped with an incandescent flash which works similar to a home compact camera. This flash although powerful, should not be used when capturing footage of nocturnal animals as a bright flash can often scare and disorientate the animal causing injury, and also attract unwanted attention from humans who may steal the camera.
The Spypoint infrared cameras and Stealth Cam Prowler HD trail cameras feature a Stealth IR system which uses a series of high power infra red LED emitters to illuminate the subject some distance in front of the camera.
These infrared cameras are invisible to the human and animal eye, and will take either still or video footage in complete darkness without alerting the subject to the fact it is on camera.
Which Trail Camera
There are so many wildlife cameras on the market today, it's often difficult to decide which is the best for you.
It really depends on a few different factors, but we have listed the most popular with their essential differences.
Most modern trail cameras utilise the SD memory card format and have their own built in, limited, storage capacity.
We recommend the SanDisk memory cards, and a capacity of 4Gb or more.
These memory cards can be swapped over on location, and the footage downloaded to your laptop when you get home for review.
Some cameras feature a LCD screen to review captured footage and this is ideal for on location checking of what the camera has captured.
Stealth Cam Prowler HD
This camera is the ultimate High Definition video camera, and is the perfect choice for obtaining high quality video footage in 1080P High Definition and also captures sound, so you can hear conversation and/or movement through foliage.
It uses a stealth infra red combined with an 8MP camera to capture high quality still footage.
The Prowler HD is the most popular trail camera for wildlife trusts as they often like to play back footage in visitor centres, or at meetings.
Spypoint PRO X
The Pro X from Spypoint is the ultimate still image camera, and features a 12MP CCD to capture ultra high quality still shots. It also captures video with sound but although not HD, we think it is fantastic quality, with rich colours, depth of field and detail.
PRO X also has a built in LCD screen for watching captured footage and is ideal for on location reviewing of what the camera trap has captured.
It also operates with a High Power Infrared emitter but has the most sensitive detection of any trail camera we have experienced.
The Stealth Cam Prowler uses a PIR detector to capture movement, but the PRO X goes a step further with a motion detector and a heat signature detector. This not only makes the Pro X ultra sensitive, but it means less false alarms as the unit will only trigger when it detects a real target, and means less false alarms with branches of trees moving near the sensor etc.
The Pro X as with all the IR/B and IR/C, can be powered by a 12V or Lithium battery pack for when you may need to leave your camera unattended for extended periods.
SpyPoint IR/A and IR/B Trail Camera
We think the Spypoint IR/B is the best allround trail camera for wildlife monitoring. It provides high quality still shots from the high resolution CCD camera, and also provides video footage in black and white at night, and colour during the day.
Using an Infra Red IR emitter, the subject never knows its photo has been taken.
Prostalk 2MP Nature Camera
The Prostalk series of trail cameras are ultra small, and ideal for locations where the camera needs to be hidden.
A low resolution however means that the images are not the best, but it's ideal for security footage or for reviewing animal movements without needing high res images for publishing.
Setting up your Infra red wildlife camera
Location really depends on the level of security your camera will need to have. If the device is on your own ground, or garden, then placing it on a tree trunk or even in a bush, will be adequate.
However if you are scouting for wildlife in an area that is visited by the public you may need to secure the camera using a security cable kit, or mount it high enough out of reach, but remember to angle the camera down to the level you wish to capture.
No point capturing birds flying past and seeing a nice bit of sky instead of the badger eating grubs below!
The Spypoint trail cameras have an adjustable detection zone which is ideal for capturing footage of animals likely to walk close by or far away from the camera.
This is crucial in a situation where you have wildlife on a path approx 15meters away, and you have vehicles on a road approx 25meters away. You do not want to trigger the camera every time a bus goes past, but you don't want to miss out on the badger at night snuffling up the trail.
When placing your camera it's crucial you test out the detection before leaving the camera to capture wildlife. The Spypoint and Stealth Cam wildlife cameras both have test modes, where you can set the camera, and then walk about in front of the camera in the area you feel is most likely to get animal traffic.
I use my labrador pup as a bit of a "test dog". By simply leaving a few dog biscuits on the trail, I set her off to find them and watch that the camera picks up movement. My theory is a small lab pup is a more realistic target than a 15stone human.
Once you know the camera is detecting the zone you wish to capture, you need to think about what type of footage you need.
A series of still shots can be fired off, or a video of a variable duration. You can also set a time delay between triggers, so that you can have as little or as much footage as you like.
A customer of ours who monitors badger growth finds it handy to scatter a few raisins in front of the camera, and she records footage of the badgers as a video clip, and then has plenty of time to review the footage and record any data she needs.
Whatever camera you decide to go for, it's amazing just what goes on at the bottom of your garden whilst you are asleep.
We have seen lots of amazing footage from bears to badgers, and wolves to window cleaners, and even some footage from the USA captured on a Prowler HD which is mind boggling, could it really be bigfoot......?
Enjoy using your Trail Camera, and look out for the many online "best trail camera photo" competitions.
Infrared trail cameras are essentially mobile digital cameras which have a motion detection system that detects a human or animal intruder into an area, and triggers a camera which takes either a series of still images, or video footage.
Primarily designed for hunters to scout deer patterns in a hunting zone, these cameras are now more and more used for wildlife observation.
BBC Countryfile recently featured their Stealth Cam Prowler HD infra red scouting camera, showing how they can be used to great effect to capture footage of elusive animals such as river otters and badgers.
The RHS Chelsea Flower Show coverage on BBC also recommends the use of these infra red cameras for people looking to see who or what is lurking around their garden at night, and suggested they are particularly useful for capturing footage of the nocturnal movements of the badger.
Infrared and incandescent wildlife cameras
Some trail cameras are equipped with an incandescent flash which works similar to a home compact camera. This flash although powerful, should not be used when capturing footage of nocturnal animals as a bright flash can often scare and disorientate the animal causing injury, and also attract unwanted attention from humans who may steal the camera.
