First pair of thoracic appendages specialized as maxilliped; other thoracic appendages without exopodites.

Despite their intriguing looks and substantial size, relatively little is known about giant isopods. Meet The Giant Isopod, The 20-Inch-Long Crustacean Of Your Nightmares. Because light is extremely faint in the deep sea, the giant isopod has developed large antennae to help it feel its way around as it crawls along the ocean floor. 'They're a nice curiosity, but there aren't many people formulating research around them, so there are still a lot of unanswered questions.'. 'We've got one in the collection that was collected from Dry Tortugas, in the Florida Keys, USA,' says Miranda.

Nonetheless, its health does not appear to have suffered from the lack of food. Monday - Sunday Vampire Squid Giant isopods can live 500 metres or more below the ocean surface. It is suggested that to find prey, they rely mainly on chemoreception and possibly mechanoreception, a sensory receptor that responds to mechanical pressure or distortion.

It is widely believed that they are scavengers; however, there is some evidence that they are also facultative predators, feeding on both live and dead animals.

But even though these full-grown giant isopods look super fierce, their soft underbellies still make them vulnerable to threats. Giant isopods are invertebrates with dorso-ventrally compressed bodies that are protected by thick and strong calcareous exoskeletons composed of overlapping segments.

Now imagine one of these insects, but enlarged several thousand times - it might sound like something out of a horror movie, but these enormous underwater crustaceans are very much the real deal. Giant isopods inhabit depths of 170 to 2140 m (550 to 7020 ft). yoppy/FlickrScientists suspect their oversized bodies could be an adaptation to the harsh environment of the ocean floor. It does not seem giant sized, but it is much larger than most deep-sea isopods which grow to about 2 centimetres (half an inch) long. Layers of the Ocean Bypassing the larval stage greatly enhances the young isopod's chances of survival. They’re not bugs. The abdomen has five segments called pleonites, each with two branches. They can reach more than 30 centimetres from head to tail. Bottom dwellers, they prefer mud or clay seafloor. It is benthic because it lives on the bottom of the ocean.

This would mean that animals can safely grow to larger sizes.

These eggs are thought to be the largest of all the marine invertebrates.

Schotte, M., B.F. Kensley and S. Shilling. Even though it ranks as the world’s largest isopod, it’s actually not the biggest crustacean in the world. This allows it to be strong and flexible at the same time. It’s a sea creature so ready to feast that it could eat an entire whale on its own — as long as the whale is no longer alive. And just like its land-based counterpart, the isopod has compound eyes, with over 4,000 individual facets. Isopods rely on food falling from closer to the surface, as the seafloor is mostly barren.

It has large compound eyes. The isopods have sensory adaptations to help them navigate in the dark.
