Body usually 25-40 mm, can be 80 mm. Whitish to light yellow. Narrow band of yellow around margin and tips of tubercles are bright yellow. Has bipinnate gills, numbering six. Dorsum feels warty and gritty to touch, due to spicules.

Biology/Natural History: Feeds on sponges, including Halichondria panicea, Myxilla incrustans, and Higginsia sp. According to Baltzley et al.,, many gastropods, including this species, have a special network of pedal ganglia in their foot which assists in crawling. The two main neurons involved produce pedal peptides which elicit an increase in the rate of beating of cilia on the foot, resulting in crawling.

Cadlina luteomarginata
provided by wikipedia EN
Cadlina luteomarginata, common name the yellow-edged cadlina, is a species of colorful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Cadlinidae.[1]
Distribution
This dorid nudibranch lives in the eastern Pacific from Alaska to Mexico. Reports of this species from the eastern coast of North America, need to be investigated. Currently, there is no concrete evidence that this species occurs in the Atlantic Ocean.
Description
The yellow-edged cadlina is a white, oval-shaped seaslug with yellow projections on the dorsum and a bright yellow rim to the mantle. It shows near the rear end a ring of six yellow-tipped feathery gills and rhinophores. The antennae are comblike. The radula has strongly hooked lateral teeth. Their subepithelial glands are compound and consist of large vacuoles with bluish stained content. Agglomerations of glandular tissue can be found on the apex of the tubercles.[2]
C. luteomarginata produces the twenty-three carbon terpenoid luteone.[3]
Life habits
This species lives under rocks and in tidepools from the intertidal zone to a depth of about 20 m in the circalittoral zone. It eats several species of spiculate sponges and also sponges from the order Dendroceratida. It is preyed upon by seastars, such as Solaster dawsoni.

Cadlina luteomarginata: Brief Summary
provided by wikipedia EN
Cadlina luteomarginata, common name the yellow-edged cadlina, is a species of colorful sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Cadlinidae.
This Cadlina luteomarginata is out of the water on the side of a
California tidepool, therefore its
rhinophores and
gills have collapsed against its body.
