The left-handed hermit crabs (Diogenidae) are similar to the Paguridae , only with them the left claw is usually larger. With it, the opening of the snail shell in which the cancer lives can be closed. Like all decapods , they have five pairs of limbs, a pair of scissor legs, two pairs of walking legs that protrude from the snail shell and two pairs of smaller, stunted legs with which they hold the snail shell in place.
There are around 350 species , including 50 in the genus Dardanus . Dardanus arrosor lives in symbiosis with the parasite rose ( Calliactis parasitica ), which it plants on the casing. If he changes it, he removes his anemones and places them on the new snail shell. The species Paguristes oculatus also forms a symbiosis with parasite roses . There are also left-handed hermit crabs that do not use a snail shell, but rather the sea anemones put themselves directly on their bodies.
Some smaller species of the Diogenidae such as Calcinus , Clibanarius and Paguristes , as eaters of algae and residues, are popular roommates in coral reef aquariums with seawater aquarists.
The eponymous genus Diogenes is named after the ancient Greek philosopher Diogenes von Sinope, who, according to legend, lived in a barrel.
