Are Isopods Insects? No, They Are More Closely Related to Crabs: An Evolutionary Journey Isopods may all look similar, but there is a huge variation between species, from the tiny Microcerberidae growing to less than 2mm, through to the Giant Isopods growing to 50cm at least, with much larger examples being reported, but never proven. Isopods are not insects; they are crustaceans, more closely.. The most familiar isopod is probably the terrestrial pill bug (sow bug or wood louse), which can be found scurrying around any backyard in moist, dark conditions. The largest isopod species are those from the genus Bathynomus.

Most are free-living, but a number of marine species are parasitic on other animals. They are usually inconspicuous. Most of the 10,000 species, which include the pill bug, the sow bug, and the gribble (qq.v.), are from 0.7 to 35 mm (0.28.. Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice 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. This ability gives woodlice in this family their common names of pill bugs[1] or rolly pollies. [2] Other.
