Interesting facts

Giant isopods are related to the roly-polies you find in your garden, but much, much bigger!

Sometimes, scientists catch them and they've eaten so much, they look like bloated sausages!

These amazing creatures have been around for millions of years, barely changing their ancient design!

They spend most of their lives creeping along the freezing-cold, super-dark ocean floor!

Special abilities

Giant Isopod can survive for years without eating, because they can slow down their metabolism to extreme levels when food is scarce.

Giant Isopod has large, widely spaced compound eyes that help them detect faint bioluminescence and movement in the dark ocean depths.

Giant Isopod can curl into a tight ball, protecting its softer underside from predators with its hard, segmented exoskeleton.
