Is a crab a vertebrate yes or no?

What is a hermit crab classified as?
class Crustacea
Hermit crab, any crab of the families Paguridae and Coenobitidae (order Decapoda of the class Crustacea). These crabs use empty snail shells (e.g., whelk or periwinkle) or other hollow objects as a shelter for partial containment and protection of the body.
Will hermit crabs eat dead hermit crabs?
Snacking on dead members of the same species is widespread among creatures ranging from orangutans to octopuses. Hermit crabs, too, are no strangers to this practice. These crustaceans pick at their dead with mini pinchers and gain nutritional benefits from consuming the flesh of former neighbors.
What animals can live with hermit crabs?
Clownfish, damselfish, gobies, cardinalfish, and wrasses are good tankmates for hermit crabs. Avoid putting goldfish, betta fish, or cichlids with hermit crabs. Pairing hermit crabs with fish can be rewarding.
Why would a hermit crab be out of its shell?
Shell evacuation happens when your crab needs to “trade up” both its housing and its exoskeleton in order to accommodate its larger body size. Stress, an inhospitable environment, poor fitting shell (too large, too small, too heavy) and uninvited company can all cause a hermit crab to exit its shell.
Can an anemone eat a crab?
They eat small fish, mussels, crabs, and sea urchins. It seems reasonable, then, that the anemones are likely to eat most any meaty morsel with which it happens to come into contact–that doesn’t swim or flap away.
