Recorded distribution in Britain and IrelandRecorded from only the south and west coasts of the UK as far north as Angelsey and south and west coasts of Ireland.
Global distributionFound south to the Azores, the Mediterranean and Black Seas.
HabitatFound intertidally on open or sheltered rocky coasts living in crevices or under rocks. Sphaeroma serratum may be found near areas influenced by freshwater but isn't found in truly estaurine areas, where it is replaced by other species.
- Broad oval body.
- Dorsal surface of pleotelson smooth.
- Pleotelson almost trapezoidal.
- Uropod exopod has distinctly serrated outer edge.
Additional informationThis marine species can be confused with the more estaurine species Lekanesphaera levii, Lekanesphaera rugicauda and Lekanesphaera hookeri. The former also has a smooth pleotelson, but Lekanesphaera levii has indistinct crenulations on the uropod exopod and a more triangular pleotleson which may extend beyod the tips of the uropods, While the pleotelson of the latter two is covered in small tubercles or two longitudinal rows of raised tubercles respectively.
