Some isopods are adorable. These are my favorite isopods.
Armadillidiidae is a family of woodlice, a terrestrial
crustacean group in the order Isopoda. Unlike members of other
woodlouse families, members of this family can roll into a ball,
an ability they share with the outwardly similar but unrelated
pill millipedes and other animals. It is this ability which
gives woodlice in this family their common name of pill bugs,
roly polies or potato bugs. The best known species in the family
is Armadillidium vulgare, the common pill bug. Woodlice in the
family Armadillidiidae are able to form their bodies into a ball
shape, in a process known as conglobation. This behaviour is
shared with pill millipedes (which are often confused with pill
bugs), armadillos and cuckoo wasps. This behaviour may be
triggered by stimuli such as vibrations or pressure, and is a
key defence against predation; it also serves to reduce water
loss through respiration.
