Salt-And-Pepper Doris

Aegires albopunctatus

This species of nudibranch, known as the salt-and-pepper doris, exhibits a body shape reminiscent of a squarish torpedo and can grow up to 0.9 inches (23 mm) in length. Its coloration ranges from bright white to dull yellowish-gray, adorned with small dark and white spots that mimic ground salt and pepper. The larger dark spots appear black or dark brown, while the white flecks are more pronounced on grayer individuals. The body is firm due to spicules from the sponges it consumes, and it features short, cylindrical tubercles along its surface. Salt-and-pepper doris can be found in the Eastern Pacific Ocean, specifically along the coasts from British Columbia, Canada, to Baja California, Mexico. They inhabit low intertidal zones and shallow subtidal areas, typically residing in sheltered rocky tide pools and on wharf pilings, down to depths of 100 feet (30 m). This nudibranch feeds exclusively on calcareous sponges from the genera Leucetta, Leucilla, and possibly Leucosolenia. As a simultaneous hermaphrodite, it engages in mating behaviors where individuals wrestle for dominance, with the victorious one penetrating the other to fertilize eggs, which are then deposited on a substrate. Encounters with this species during dives can reveal its unique coloration and feeding habits, making it a noteworthy sight for divers exploring its habitat. The conservation status of the salt-and-pepper doris is not evaluated.
