“A hermit crab cannot make its own shell to live in but has to find an empty shell to occupy. Once found, he backs into the shell; his twisted body is ideally designed to fit into a spiral shell.
Often, a hermit crab carries a sea anemone on his shell. Sea anemones are covered with stinging cells, which release poison and kill the crab’s enemies when touched. When a hermit crab has to move to a new home, he will “plant” the anemone on his new shell.
How did the hermit crab get his spirally curved body that fits perfectly in a shell? How did he discover that it was good to have a sea anemone living on his shell? How does evolution explain these features? It is much easier to explain them if we accept that God created the hermit crab with these special features.”
