'''''Exosphaeroma''''' is a genus of [marine](/source/Marine_(ocean)) [isopod](/source/isopod) of the [family](/source/Family_(taxonomy)) [Sphaeromatidae](/source/Sphaeromatidae). This genus is found in shallow ocean waters worldwide. It is notable for being one of the few genera of sphaeromatid to be found in the southern reaches of the [Southern Ocean](/source/Southern_Ocean). The greatest diversity of ''Exosphaeroma'' occurs in the [Southern Hemisphere](/source/Southern_Hemisphere).[{{cite journal |last1=Wall |first1=Adam R. |last2=Bruce |first2=Niel L. |last3=Wetzer |first3=Regina |title=Status of ''Exosphaeroma amplicauda'' (Stimpson, 1857), ''E. aphrodita'' (Boone, 1923) and description of three new species (Crustacea, Isopoda, Sphaeromatidae) from the north-eastern Pacific |journal=ZooKeys |date=18 May 2015 |issue=504 |pages=11–58 |doi=10.3897/zookeys.504.8049 |pmid=26019675 |url=https://zookeys.pensoft.net/articles.php?id=5300&display_type=list&element_type=9|pmc=4443524 |doi-access=free }}]
