Polycera
sp. #3

 
Polycera sp. #3
Maximum size:  6 mm.

Identification:  This is a cream to dusky-gray species densely flecked with white. Clusters of dark brown spots occur on the sides, at the bases of the rhinophores and at the base of the branchia. The notum may have scattered light brown to orange spots. The notum is covered with irregular, conical tubercles and tubercles on the rachis are tipped with yellow spots. The rhinophores are large with nipple-like tips (somewhat contractile). There are clear areas at the bases of the rhinophores around the eye spots while the margins of the head are angular and densely flecked with white. The latter characters distinguish it from Polycera japonica.

Natural history:  Polycera sp. #3 is a moderately rare species known from several animals found in moderately exposed rocky habitats at depths of 3-12 m (11-38 ft).

Distribution:  Big Island, Maui and Oahu: also known from Malaysia and Papua New Guinea.

Taxonomic notes:  It was first recorded in Hawaii from Hawaii Kai, Oahu by Darrell Takaoka in Feb, 1999.
