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.

recorded
in
Hawaii at Hale'iwa,
