Ceratophyllidia
sp. #1

 
Ceratophyllidia sp. #1
Maximum size:  about 100 mm.

Identification:  This species possesses soft, stalked, globular tubercles on its notum. Scott Johnson reports (pers. com.) that its body is firm and translucent white, with a slightly yellowish area middorsally and a visibly spiculose mantle. There are a few very light, brown spots on the mantle that are usually obscured by the tubercles. The larger tubercles are cream with brown and white spots that are absent on the smaller tubercles. The rhinophores are translucent white, tall and pointed with about eight lamellae. The foot and gills are white.

Natural history:  Ceratophyllidia sp. #1 is known from only two animals, one found in the open on a rock wall at 8 m (26 ft) and the other under a ledge at 9 m (30 ft). They were in exposed to highly exposed locations. The stalked tubercles can be autotomized when the animal is disturbed.

Distribution:  Oahu: widely distributed in the western & central Pacific.

Taxonomic notes:  First recorded in Hawaii at Hale'iwa, Oahu by Scott Johnson in July 24, 1980.
