Creatures of the Arctic Ocean
Giant Isopods
These huge, unattractive isopods are a relative of the
woodlouse – and they can curl up like one too! They
are very important scavengers who prefer the muddy
depths of the Arctic Ocean. They live and hunt alone
– using four jaws to consume their food! They feed on
dead animals that fall from above mostly, but it is also
