Sphaeroma |
Sphaeromatidae 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]
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]
The family contains the following genera: [5]
