Bermudella pellucida (Burn, 1967)
Maximum size: 8.5 mm.
Identification:
This is a dusky cream animal decorated with random brown lines. The
notum is covered with moderately long, slender processes. The
rhinophores have cup-like lamellae on their posterior faces and brown
medial bands.
Natural history:
Bermudella pellucida
is a common species on the exposed accretion platform at Maalaea Bay
but is rare at other sites. (Note 1) At that site, it occurs
at 2-5 m (6-16 ft). Scott Johnson also found it
to be fairly common in a somewhat more protected area at Magic Island,
Oahu. It feeds on the bryozoan Zoobotryon
sp. (now changed to Amathia). (Gosliner, et. al., 2008) It lays an egg mass composed of an
irregularly
arranged white ribbon that hatches in three to four days in the
laboratory.
Distribution:
Big Island, Maui, Oahu and Kauai: widely distributed in the Indo-Pacific.
Taxonomic notes:
It was probably first reported in Hawaii from Kewalo Basin, Oahu, in
Oct., 1963
(Kay & Young, 1969--as Okenia
sp.). It was formerly included as Okenia pellucida.

Observations and comments:
Note
1: Kelly McCaffrey reported finding
"dozens and dozens" of animals clustered on their host bryozoan (along with many egg
masses) at Maalaea Bay on Jan. 17, 2022.
