Hermit Crab 2

Hermit Crab 2

Hermit crabs are crustaceans of the superfamily Paguroidea. Most of the 1100 species possess an asymmetrical abdomen which is concealed in an empty gastropod shell that is carried around by the hermit crab. This vulnerable abdomen is protected from predators by a salvaged empty seashell carried by the hermit crab, into which its whole body can retract. As hermit crabs grow they require larger shells. A hermit crab with a shell that is too small cannot grow as fast as those with well-fitting shells, and are more likely to be eaten if it cannot retract completely into the shell.
