Sphaeromatidae

Sphaeromatidae (marine pillbug family) is a family of isopods, often encountered on rocky shores and in shelf waters in temperate zones.[1] The family includes almost 100 genera and 619 known marine species (and about 65 in fresh water). Within these genera, there are groups that share distinctive morphologies; further research may reclassify these genus-groups as separate families.[2]

Description

Many species have a dorsoventrally compressed body shape, often with a vaulted dorsum, and some are strongly flattened (scale-like).[2]

Sphaeromatidae are browsers or detritus feeders. Xynosphaera appear to have incisory mandibles,;[2] Xynosphaera colemani burrows into the tissue of alcyonacean corals.[3] Some genera of Sphaeromatidae associate with sponges, particularly Oxinasphaera.[4]
