How uncomfortable it is to grow
The hermit crab, a crustacean, is very weird. This little animal settles inside empty shells, but as he grows during his life, he has to find a new house, looking for bigger and bigger shells. In order to defend himself from predators, he covers his house with actinias (sea animals similar to flowers) that he transports on the seabed. Moreover, actinias eat the leftovers of the hermit crab’s food.
