apparently rare on the other islands, Flabellina
exoptata appears to be
moderately common on Oahu in moderately exposed to highly exposed rocky

was first recorded in Hawaii off Pearl Harbor, Oahu by Scott Johnson
Jan. 6, 1977. The name means "much desired," in reference to the
beauty of this species. It's referred to as the "desirable nudibranch"
in Hoover, 2006 and illustrated under Caloria
indica in Hoover, 1998. It was deleted in the 5th printing of
Hoover, 2006 but restored in the 2019 printing). Some sources use Coryphellina exoptata.
