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

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

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 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.
