7 Giant Isopod
In all fairness, the giant isopod does look like a pet that those “Predator” creatures would own, and its appearance is only one reason as to why its on this list. They’re the largest known members of the isopod family, a group of crustaceans closely related to crabs and shrimps, and though they’re not usually fished commercially, they can be found in restaurants in northern Taiwan, where they’re boiled and served as food.
The giant isopod can grow to a length of over 16 inches and its enormous size is due to the phenomenon known as deep sea gigantism. This is the prospective tendency that deep sea crustaceans and other animals grow to a much larger size in shallower waters to deal with enormous pressures.
Unlike the species they’re related to, the giant isopod is carnivorous crustacean that scavenges the deep sea floor in search of food. Since its extremely scarce at these depths, the isopod is forced to adapt to eat whatever it can which includes the bodies of dead whales, fish, squid, sponges and sea cucumbers. They can also go long periods of time without eating as its humongous (and frightening) kind has been known to survive over eight weeks without eating food when kept in captivity.
