Excirolana
Excirolana is a genus of marine isopod crustaceans in the family Cirolanidae, comprising approximately 15 described species. Members are specialized inhabitants of exposed sandy beaches in tropical and warm temperate regions worldwide. The genus is characterized by ovoviviparous reproduction, in which embryos develop internally within paired uteri rather than in an external brood pouch. This reproductive mode is considered an adaptation to the harsh environmental conditions of intertidal sandy habitats.
