Limacia cockerelli is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Polyceridae. [2] [3]
This species is found from the West coast of North America, ranging from Vancouver Island, British Columbia, Canada to San Diego. It was also reported in the Gulf of California at Bahía de los Ángeles but those records are now known to be the similar species Limacia mcdonaldi . [4] [5]
This species reaches lengths of 26 mm (1.0 in). It has long dorsal papillae with orange-red tips and white branchial plumes with red tips. [6] There is a broad band of white tubercles down the middle of the dorsum which may sometimes have a small spot of orange at the apex. The second form, found in areas south of Point Conception has tubercles that are in a mid-dorsal line, slightly longer and tipped with orange. [7] Another form in California has large red blotches on the dorsum. The eggs of Limacia cockerelli are pink and develop after 17 days (at 10–13 °C [50–55 °F]) into hatching planktotrophic veligers. It was thought likely that the southern form represented a species complex. [8] This was confirmed in 2017 with the description of Limacia mcdonaldi . [5]
This animal preys exclusively on the orange-brown coloured bryozoan, Hincksina velata . [4]
First described by Frank MacFarland in 1905 and originally named Laila cockerelli in honour of Theodore D. A. Cockerell. [1]

The Doridina, common name dorid nudibranchs, are a taxonomic suborder of sea snails or slugs, marine gastropod molluscs in the order Nudibranchia. Bouchet & Rocroi (2005) rejected the name Anthobranchia on the grounds that it also included Onchidium at the time of original publication. Doridina is equivalent and used in the latest classification.

Limacia mcdonaldi, or McDonald's dorid, is a species of nudibranch native to the coast of California. It grows up to 26 mm in length and was previously confused with Limacia cockerelli from which it is easily differentiated by the row of orange spots down the centre of the back. It was named in honor of nudibranch expert Gary McDonald.
