Dendrodoris sp. #9
Maximum size: 150-200 mm.
Identification:
This
is
a large, strongly tuberculate species. The primary tubercles are
mushroom-shaped with complex secondary tubercles that give them a cauliflower/berry-like surface. The
background
color is cream with dusky shading in the depressions while the
secondary tubercles have dusky apical shading variably grading from blue-brown marginally to green on the
larger primary tubercles. The rhinophores and branchia are
lined with white and the underside probably has white patches. There are
no "refraction lines" on the crests of the secondary tubercles. The margin is
strongly and irregularly undulating but without finer, radiating folds. The central
primary tubercles are arranged in an "X."
Natural history:
Dendrodoris sp.
#9 is known from one animal found at a depth of 6-9 m (20-30 ft) at a
rocky, moderately exposed site. It was crawling in the open during the
day.
Distribution:
Maui: widely distributed in the Indo-Pacific.
Taxonomic notes: This species
was first recorded in Hawaii at "Five Caves", Maui by Sarah Bashaw on Dec. 10, 2019. It is lumped under Dendrodoris tuberculosa in many sources, including Gosliner, et. al. (2018). However, it differs from what we are calling D. tuberculosa
in tubercle form, color, "refraction lines" and marginal folds. The
conical tubercles shown in the painting accompanying the original
description of D. tuberculosa support that use of the name. For another example, see this species and D. tuberculosa on Scott Johnson's site.
