5. Giant Isopod
The giant isopod (scientifically known as Bathynomusgiganteus), is the biggest animal from the isopod family and it is a deep sea fish. Its appearance closely resembles that of the small pillbugs commonly found in the garden.
This is a carnivorous deep sea fish that spends most of its time scavenging in the floor of the deep sea. Since food is obviously scarce at these lengths of the sea, the Isopod has adapted to eat any food that comes its way. You can find isopods all over the world at the depths of about 2000 feet of the seas.
