Distribution
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]
Description
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]
