Unidentified Caliphyllid #1
|Maximum size: about 20 mm.
This is a translucent-cream species with heavily papillate cerata and
rhinophores. The centers of the cerata contain dense, irregular branches
of the digestive gland. Fine, terminal branches extend to their edges
and, sometimes, enter the papillae. The rhinophores are frosted with
brown and there are a few minute white flecks, particularly on the
Natural history: Unidentified Caliphyllid #1 is known from one animal found at < 1 m (< 3 ft) at a moderately protected site.
Taxonomic notes: The over-all form and rhinophores are reminiscent of Mourgona
but the branching pattern of the digestive gland isn't a good match for
that genus. It was first recorded in Hawaii from Hekili Point, Maui by
Karolle Wall on Jan. 2, 2023.
