Phyllidiopsis fissuratus Brunckhorst,
1993

Maximum size: 60 mm.
Identification:
This
is a large, elongate species with many tall, pink compound
tubercles with irregular upper surfaces. The black dorsum appears as
deep fissures
meandering among the tubercles. Black lines extend onto the tops of the
tubercles and the mantle edge is pink interrupted by
black rays. The rhinophores are mostly black with some pink on the
bottom anterior edge. The fused oral tentacles are pink. It
can be
distinguished from the much more common Phyllidiella
pustulosa by its black marginal rays, pink-based rhinophores
and fused oral
tentacles.
Natural history:
Phyllidiopsis fissuratus
is a rare species found in the open in moderately protected to exposed
rocky locations from 10-26 m (33-85 ft).
Distribution:
Maui, Molokai and Oahu: widely distributed in the western & central
Pacific.
Taxonomic notes:
It
was first recorded in Hawaii at Makua, Oahu by Scott Johnson on Oct.
28,
1985. The name
refers to the deeply fissured appearance of the dorsal surface.
