White-Speckled Dorid

Doriopsilla fulva

Doriopsilla fulva is a pale yellow nudibranch that can reach a size of up to 33 mm. Its body features opaque white dots at the tips of the dorsal tubercles, while the areas between the tubercles remain unmarked. The rhinophores are pale yellow with a club shape and a white stalk, displaying 10-12 lamellae. This species is often confused with Doriopsilla albopunctata and other species within a pseudocryptic complex, making careful observation essential for accurate identification. This nudibranch inhabits the eastern Pacific, specifically from Point Loma in San Diego to Humboldt County in California. It is typically found in benthic environments, often associated with sponge gardens, where it thrives. Doriopsilla fulva primarily feeds on sponges, which form a crucial part of its diet. As a simultaneous hermaphrodite, Doriopsilla fulva engages in a unique mating behavior where two individuals use their penises to stimulate each other, determining which will act as the male. After mating, eggs are laid on a substrate, developing into planktonic larvae before maturing into adults. While encounters with this species can be common, its conservation status has not been evaluated, leaving its long-term prospects uncertain.
