'''Sphaeromatidae''', the '''seapills''', is a family of isopods, often encountered on rocky shores and in shelf waters in temperate zones.<ref>{{cite book |last1=Poore |first1=Gary CB |last2=Lew Ton |first2=Helen M |last3=Bruce |first3=Niel L. |year=2002 |chapter=Sphaeromatidae Latreille, 1825 |editor1-last=Poore |editor1-first=Gary C.

Within these genera, there are groups that share distinctive morphologies; further research may reclassify these genus-groups as separate families.<ref name=Diversity>{{cite journal |last1=Poore |first1=Gary C.

==Description== Many species have a dorsoventrally compressed body shape, often with a vaulted dorsum, and some are strongly flattened (scale-like).<ref name=Diversity/>
==Ecology== Sphaeromatidae are browsers or detritus feeders. Xynosphaera appear to have incisory mandibles;<ref name=Diversity/> ''Xynosphaera colemani'' burrows into the tissue of alcyonacean corals.<ref>Bruce NL (2003) New genera and species of sphaeromatid isopod crustaceans from Australian marine coastal waters.
