Baeolidia
sp. #2

 
Baeolidia sp. #2
Maximum size:  26 mm. (Kay, 1979).

Identification:  This is a slender species with papillae on the posterior edge of  its rhinophores. The cerata have larger brown spots than in Baeolidia nodosa and fewer papillae. The notum is decorated by a series of yellow rings enclosing cloudy, pale-pink spots. Larger animals have more cerata in each arc.

Natural history:  Baeolidia sp. #1 is a moderately common diurnal species found in protected to exposed rocky habitats and in Halimeda kanaloana beds. It occurs at < 1 to 18 m (< 3 to 59 ft). A large animal dislodged from a colony of the small form of Aiptasia pulchella rolled into a ball making it look remarkably similar to a dislodged anemone. Large animals found associated with a bloom of the swimming anemone Boloceroides mcmurrichi fed readily on that species in a dish. (see photos) Its egg mass is a white spiral composed of a "kinked" ribbon. Hatching occurres in about three days in the laboratory.

Distribution:  Maui, Oahu and Kauai: widely distributed in the western & central Pacific.

Taxonomic notes:  This is the species listed as Baeolidia nodosa (Haefelfinger and Stamm, 1958) in Bertsch and Johnson, 1981 and Kay, 1979. It is also listed as Limenandra sp. 1 on the Sea Slug Forum. It was first recorded in Hawaii at Kaneohe Bay, Oahu by Terry Gosliner on Sept. 15, 1973.
