A living aquatic creature such as a snail, clam, or mollusk.
Crawfish do not ever come out of their shell. The shell is a type of exoskeleton.
Shell
No, snails do not leave their shell to burrow.
NO they don't because they they stay in shell
Its not that they come out of their shell to become bigger they become bigger and outgrow their shell and are forced to migrate to a new, bigger shell *ESSENTIAL*
Cicadas do.
they go in to there shell or come out of there shell i think ahhaa lol
turtle
No, they stay in their shell at all times unless they get eaten or die.
snails never come completely out of there shell there shell might break so they can grow a new one. but a snail performs torsion in witch its body twist into the shell they create and can not leave there shell but can grow the shell bigger so there shell grows with them
As hermit crabs grow and increase in size they need to come out of their shell in order to find a larger shell to live in.
No pearls come out of an oyster shell
