The populations of all species in a habitat that associate with one another form a community . Use chapter 47 as a reference to answer the following questions that examine communities.
Hermit crabs are crustaceans who have a soft abdomen and live in the ocean.
To compensate for the lack of a hard shell, these crabs burrow under a shell. The shell serves as their home until they grow too large to fit inside and they seek a new shell. Sea anemones, which possess long fingerlike tendrils, often attach to the top of the hermit crab's shell. The tendrils contain a poison that is lethal to many fish. When the hermit crab walks along the ocean floor, it carries the shell and sea anemones with it.
