Exosphaeroma
Spherical Isopods, marine pillbugs
Exosphaeroma is a genus of marine isopods in the family Sphaeromatidae, found in shallow ocean waters worldwide. The genus exhibits highest diversity in the Southern Hemisphere and is notably one of few sphaeromatid genera occurring in the southern reaches of the Southern Ocean. Recent taxonomic work has described new species from the northeastern Pacific, including one discovered in urban Los Angeles and another from 142-year-old Alaskan collections.
Seroloidea
Seroloidea is a superfamily of marine isopod crustaceans within the suborder Sphaeromatidea. It comprises six families, four of which are extant and two extinct. The superfamily was established by Dana in 1852. Seroloidea is distinguished from other sphaeromatidean superfamilies by unique morphological characteristics of its constituent families, particularly the Serolidae.
