Adaptaciones Especiales

Es uno de los pocos crustaceos terrestres. Excavan durante el dìa para mantenerse hùmedos. Sus exoesquèletos tienen 10 segmentos articulados libres que les permiten enroscarse en forma de pelota para protegerse de sus predadores.

Organizaciòn Social

Las cochinillas de tierra son altamente suceptible a la deshidraciòn, ellos a veces se agrupan para reducir evaporaciòn.
