The giant isopod, known scientifically as Bathynomus giganteus, is the largest known member of the isopod family. It is very closely related to the small pillbugs that you can find in the garden. It is a carnivorous crustacean that spends its time scavenging the deep ocean floor. Food is extremely scarce at these great depths, so the isopod has adapted to eat what ever happens to fall to the ocean floor from above. It will also feed on some of the small invertebrates that live at these…
Even though the Giant Isopod is a deep sea dwelling creature, it might look strangely familiar to you. A close cousin of the Giant Isopod is the much smaller terrestrial Woodlouse (3-30 mm). But you might know the Woodlouse by one of its more common nicknames like pill bug or roly-poly. Woodlice are usually found in damp, dark places, rotting logs and typically eat decaying plant material.
Genetically, Woodlice and Giant Isopods have been unchanged for over 160 million years.
Cthulhu's Pet? Giant Isopod (2.5 Feet!) Found Attached To Underwater Robot
this giant 2.5 foot isopod (sea bug) was found attached to a robotic submersible at a depth of 8,500ft. They're apparently quite abundant in the cold, dark waters of the Atlantic where they scavenge for food.
Giant Isopods of the Deep: As scavengers of the abyss, Giant Isopods are carnivorous creatures that will feast on anything they can get their spiny claws on including dead whales, fish, and squid. They also devour slow moving prey like sea cucumbers and sponges.
Giant Isopod | This one is the largest of the existing isopods. “The enormous size of the giant isopod is a result of a phenomenon known as deep sea gigantism. This is the tendency of deep sea crustaceans and other animals to grow to a much larger size than similar species in shallower waters.” (Image credits: Littoraria)
Giant isopods (Bathynomus giganteus) Giant isopods look like they might eat you in your sleep if given the chance, and they just might—if they could only catch you. Giant isopods live in the deep sea, where they catch what prey they can, including slow-moving sea cucumbers, sponges, and nematodes, but mostly scavenge the dead carcasses of fish, squid and whales.
