distinctive species is cream with dark brown spots and a broad
oral veil fringed with short white papillae.
is a rarely seen sand dweller that partially buries itself in the sand
during the day (usually with the
rhinophores and posterior siphon exposed). It forages for small
invertebrates at night.
(Note 1) It's been recorded from < 1 to 65 m (< 3 to 213 ft), the latter
dredging, and can swim in a manner
similar to Hexabranchus.
(Kay, 1979). It probably lays a light brown, sand-anchored egg mass. (Note 2)

Observations and comments:
Note 1: To see a video of one feeding (by Patty Daly) go here.
Note 2: On June 18, 2013 two light brown, sand-anchored egg masses were found in the general vicinity of the two E. luniceps
found by Gordon Hendler. The masses seemed similar in form to other
pleurobranch egg masses but were anchored in the sand at one end rather
than attached to an object. By process of elimination, it seems likely
that they were laid by E. luniceps (although it hasn't been
confirmed directly). On average, they were several cm in length but they
folded and stretched dramatically (accordion-fashion) as they swayed in
the surge. (see photos)
