Salt-And-Pepper Doris

The salt-and-pepper doris grows up to 0.9 in (23 mm) in length. Its body is somewhat shaped like a squarish torpedo, and ranges in color from bright white to duller, yellowish-gray shades of white. As its common name references, the salt-and-pepper doris is noted for the small dark and white spots all around its body, which resemble ground table salt and black pepper. The larger, dark "pepper" spots appear black or dark brown in color, while the white "salt" flecks may not be very distinct on brighter white individuals; they are more apparent on grayer individuals. Some individuals may have very little "pepper" spots, or none at all.

The salt-and-pepper doris occurs in the Eastern Pacific Ocean, along the coast stretching from British Columbia, Canada to Baja California, Mexico. It inhabits the low intertidal zone and the shallow subtidal zone, down to depths of 100 ft (30 m). The salt-and-pepper doris can be found in sheltered, rocky tide pools and on wharf pilings.

The salt-and-pepper doris is specialized to feed exclusively on the calcareous sponges of the genera Leucetta, Leucilla, and possibly Leucosolenia.

Like all nudibranchs, the salt-and-pepper doris is a simultaneous hermaphrodite. While mating, individuals wrestle for dominance, attempting to penetrate and impregnate the other with their penis, which is lined with small, hooked spines.
