Synidotea harfordi

Synidotea harfordi is a crustacean belonging to the family Idoteidae and order Isopoda. This species is primarily found in the coastal waters of California, USA. It inhabits shallow benthic environments, typically at depths ranging from 0 to 12 meters. Divers may encounter this species in areas with sandy or muddy bottoms, where it resides close to the substrate. The life cycle of Synidotea harfordi involves indirect sperm transfer, with eggs being brooded in a specialized pouch known as the marsupium. These eggs eventually hatch into a stage called manca postlarva before maturing into adults. The reproductive behavior of this species includes mating before and sometimes during the parturial molt. While diving, encountering Synidotea harfordi can offer a glimpse into the unique reproductive strategies of isopods. The conservation status of this species has not been evaluated by the IUCN, and there are no known threats to humans associated with it.
