Bulbaeolidia paulae Carmona, Paula, Gosliner & Cervera, 2017
Maximum size: 30 mm (Kay,
1979).
Identification:
This
species is similar in appearance to Bulbaeolidia
alba with bulbous swellings on its cerata. However, it
differs from that species in having more cerata
in each arc and is usually darker in color. The body is
cream,
mottled with brown,
particularly on the head. There are well-defined white tips on its
cerata.
Natural history:
Bulbaeolidia paulae
has been
recorded from tide pools, solution benches and
fringing reefs. (Kay, 1979) It was common on Oahu in the 1960s but
has seldom been seen in recent years (Terry Gosliner, pers. com.). On
Maui, we've seen it only in Kahului Harbor at a depth of < 4 m (<
13
ft). Although it may contract its posterior cerata slightly, it does
not erect them into a crest rhythmically in the manner of B. alba. It lays a kinked, white egg mass. A partial egg mass
(disturbed while laying) took about five days to hatch in the
laboratory.
Distribution:
Maui, Oahu, and Kauai.
Taxonomic notes:
This
is the species listed as Spurilla
japonica in Kay, 1979, Gosliner, 1980 and Kay & Schoenberg-Dole, 1991. It was first recorded in Hawaii from Kahuku, Oahu by
Allison Kay in Dec., 1962. It's listed on some sites as Aeolidiella
japonica. It represents "Aeolidiella sp. B" in Carmona, et. al., 2013.
