Hermit Crab

Hermit crabs are different than most crabs because they have a
soft body and no shell of their own. They live in abandoned
black turban and striped dog winkle shells which is why shells
should not be collected anywhere along California’s coastline.
They adapt to this physical disadvantage by using the
abandoned shells of sea snails to protect their soft bodies from
predators and the harsh tidepool environment. As scavengers,
they will feed on bits and pieces of other creatures and plants
including any of their own kind that are too slow getting into a
new snail shell.
