Giant isopod
Giant isopods are of little interest to most commercial fisheries owing to the typical scarcity of catches and because ensnared isopods are usually scavenged beyond marketability before they are recovered. The species are noted for resemblance to the common woodlouse or pill bug, to which they are related.
Giant Isopods are opportunistic, carnivorous feeders, and they have to be! They live in an area where food is scarce, and so they will gorge on whatever they can find. This often includes parts of dead fish and larger marine creatures, and it is believed that they may also hunt slow moving deep sea dwellers as well. They are also capable of surviving for weeks without food, and adaptation that helps them to survive.
giant isopod is a carnivorous crustacean that spends its time scavenging the deep sea floor. Food is extremely scarce at these great depths, so the isopod has adapted to eat what ever happens to fall from above. This includes the bodies of dead whales, fish, and squid. It is believed that the isopod will also feed on some slow-moving animals such as sea cucumbers and sponges. The giant isopod has a complex mouth that with many components that work together to pierce, shred, and disembowel their prey.
In the deep sea, critters tend become either dwarfs or giants. This is because of food limitation – small animals require less food, and very large animals are more efficient. The giant squid is the most famous example of gigantism, but the giant isopod is much more near and dear to my heart. Isopods are essentially roly-poly bugs.
