Limenandra rosanae Carmona, Pola, Gosliner & Cervera, 2014
Maximum size: 32 mm.
Identification:
This
is a slender species with papillae on the posterior edges of
its rhinophores. The cerata have larger brown spots than in Limenandra
confusa 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:
Limenandra rosanae
is a moderately common diurnal species found in protected to exposed
rocky habitats and in Halimeda
kanaloana beds. It occurs at < 1 to 29 m (< 3 to 95 ft). A
large animal dislodged from a colony of the small form of the swimming anemone, Boloceroides mcmurrichi (in shallow water) rolled into a ball making it look remarkably similar
to a
dislodged anemone. Large animals found associated with a bloom of B.
mcmurrichi in deeper water fed readily on that species in a dish. (see photos) Its egg mass
is a white spiral composed of a
"kinked" ribbon. Hatching occurs in about three days in the
laboratory.
Distribution:
Big Island, Maui, Oahu and Kauai: widely distributed in the western & central
Pacific.
Taxonomic notes:
This
is the species listed as Baeolidia
nodosa in Bertsch and Johnson,
1981, Kay, 1979 and Gosliner, 1980.
It
was first recorded in Hawaii at Kaneohe Bay, Oahu by Terry
Gosliner on Sept. 15, 1973.
