Unidentified Juliid #1
|Maximum size: 0.6 mm
(extrapolated from shell length).
has a tiny transparent shell with a curved dorsal margin.
The protoconch is identical to that of Unidentified
#2 but the hinge teeth are much better developed than
in that species. The smaller protoconch and hinge details distinguish
it from the shells of juvenile Berthelinia pseudochloris.
The animal is translucent-cream densely flecked with white dorsally.
Green and mustard-yellow flecks show through the shell and there is a
large patch of white pigment surrounding the hinge. The rhinophores are
short and flattened.
Juliid #1 is probably one of the world's smallest opisthobranchs. It's
known from only one live animal found at a moderately exposed rocky
site at 1-2 m (3-6 ft). However, substantial numbers of shells have
been found in beach drift from moderately exposed to exposed sites on
Maui and Midway Atoll suggesting that it's actually fairly common.
Maui and Midway.
#1 and #2 appear to be closely related but may fall
outside the recognized genera in the family. Live animals were probably
first recorded in Hawaii from Maalaea Bay, Maui by CP on Aug. 8, 1991.
