Hermit Crabs
Definition
Hermit crabs are not like most crabs because most crabs don’t change shells like a hermit crab does. A hermit crab is a speedy creature when near the water. They are also invertebrates and are nocturnal, but they still move around during the day because hermit crabs only sleep for a couple of hours. Hermit crabs use their first pair of legs for walking around and the other legs are for keeping their shell on. Hermit crabs are a crustacean too.
Appearance
Hermit crab’s natural colour is always a mix of orange, green, yellow, white, brown, black, blue and red. When Hermit crabs change shells you may think it is a shrimp but it isn’t, it’s a Hermit crab out of its shell. Hermit crabs grow up to 10cm long but the ones you commonly see are 10mm long.
Behaviour
Hermit crabs search everyday of their lives for new shells. When Hermit crabs mate they must be in a natural enviroment. to breed and only breed during the night. If not they will join shells.
Diet
Often when hermit crabs are a pet or being looked after mainly eat fruit, vegetables and any type of cereal.
But when they are in the wild they eat octopus brains and washed up fish.
Dangers
One of the hermit crab’s dangers is water pollution because if rubbish gets in to the tide pools then the hermit crabs die out because their home is polluted. Another danger is the changing tide pools, because they could get swept away by the sea.
Opinion
Our opinion is that hermit crabs are a fascinating creature because they switch shells all the time.
