2nd animal
|
Eubranchus sp. #8
Maximum size: 3 mm.
Identification:
This
species
has a translucent-cream body with blotchy, olive-brown pigment running
along the margins of the notum and extending into the cerata. There are
also a few darker-bown spots. The tips of the cerata are cloudy-white and lack
the transparent "windows" characteristic of Eubranchus sp. #2.
The
rhinophores and cephalic tentacles have medial orange bands and
cloudy-white tips. White pigment on the notum is irregularly distributed
and granular though it may be more diffuse in the center.
Natural history:
Eubranchus sp. #8 is known from two animals. The 1st was found on algae collected by Cecile Walsh on the Big Island.
It showed a diurnal activity pattern when held (Daniel Jennings-Kam,
pers. com.). The 2nd was found in a tide pool on Maui.
Distribution: Big Island and Maui.
Taxonomic notes:
It
was first
recorded in Hawaii from the Big Island by Cecile Walsh and Daniel
Jennings-Kam on Sept. 1, 2014. Although the overall "gestalt" seems
closer to Eubranchus, there's some chance that this species could turn out to be a Tenellia or Tergipes, instead. (Note 1)

Observations and comments:
Note
1: It's also possible that the two
animals could turn out to be different species. The grayish appearance
of the cerata and rhinophore tips in the first can be attributed to
lighting. However, if it's actually pigment, instead, that might argue
for splitting... |
