About Cadlina flavomaculata MacFarland, 1905
Cadlina flavomaculata, commonly called the yellow-spot cadlina, is a species of nudibranch. It has an ovate, translucent white mantle, paired with distinctive brown to black rhinophores. A row of large yellow spots, which are mantle glands, runs along each side of the mantle. While some recorded specimens have a yellow border along the edge of the mantle, this feature does not appear in all individuals. The branchia, or gills, range in color from white to yellow. The maximum recorded length for this species is 15 millimeters.
This nudibranch is relatively rare overall, and is found in intertidal and subtidal zones of the northeastern Pacific Ocean, ranging from Vancouver Island down to the southern tip of Baja California. It is common at some diving sites located between Monterey, Carmel, and Big Sur.
In terms of ecology, Cadlina flavomaculata feeds on the sponge species Aplysilla glacialis.
