Pentidotea
Pentidotea is a genus of marine isopods in the family Idoteidae, established by Richardson in 1905. The genus comprises approximately 13 described species of flattened, oval-shaped crustaceans found in coastal marine environments. These isopods are members of the suborder Valvifera, characterized by their ability to roll into a ball. Species in this genus are primarily associated with algae and seagrass habitats in temperate to cold waters.
