Bermudella pellucida
(Burn, 1967)
 
Bermudella pellucida
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.
