|Maximum size: about 100 mm.
hare is a cream animal densely reticulated with brown lines and
blotches that become larger near the edges of the parapodia,
rhinophores and cephalic tentacles.
is a rare species reported from the outer face of solution benches and
fringing reefs. (Watson, 1973) It's been found in Halimeda kanaloana beds at 7 m (24 ft) but also in as little at 1 m (3 ft)
(Hoover, 1998). In addition, it may be found on floating debris in open water. Unlike
other Hawaiian Aplysia spp., it can swim by
flapping its parapodia. (Note 1)
Maui, Oahu and Kauai: may be more widely distributed in the western & central
Pacific. (Note 2)
It's listed as Aplysia pulmonica Gould, 1852 in Kay, 1979 as well as Hoover, 1998 & 2006 (changed to "Aplysia sp." in 2019 printing). It's referred to
as the "pulmonate sea hare" in Hoover, 1998 & 2006. It was formerly listed as "Aplysia sp. #1" and is the same as "Aplysia sp." on page 389 in Gosliner, et. al., 2018. (Note 3)
