In this case, the lung is more suited to the ...
Hermit crab species range in size and shape, from species only a few millimeters long to Coenobita brevimanus (Indos Crab), which can approach the size of a coconut and live 12–70 years. The shell-less hermit crab Birgus latro (coconut crab) is the world's largest terrestrial invertebrate .
