Brief Information About Deep Sea Animals

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.
