Trapania palmula Gosliner & Fahey,
2008
Maximum size: about 4 mm.
Identification:
This
is a mottled cream and brown animal. The extra-branchial and
extra-rhinophoral appendages usually have diagonal, violet-blue marks at
their midpoints (though they may be absent in some).
The oral tentacles are usually tipped with yellow and there are often
yellow sub-apical spots on the extra-branchial and extra-rhinophoral
appendages.
Natural history: Trapania palmula
is known from half a dozen animals found among entoprocts growing on the sponge Spheciospongi vagabunda. They were at a moderately exposed site at a depth of about 5-7 m (16-22 ft). It
presumably feeds on the entoprocts with which it's associated. It lays an irregular, white egg mass. (Note 1)
Distribution:
Maui: widely distributed in the Pacific.
Taxonomic notes: It was first found in Hawaii at Maalaea Bay, Maui by Kelly McCaffrey on July 28, 2024.

Observations and comments:
Note
1: Jenna reported: "There were 2
animals on the same sponge today, one small and one much larger animal
appearing to deposit eggs in a linear fashion near the base of the
sponge. It was crawling along the bottom part of the sponge making it
about half way around the base before abruptly turning and crawling
rather quickly back next to its eggs."
