The DESIRABLE NUDIBRANCH, of the family
Flabellinidae, is a very tiny nudibranch found in clear waters with moderate
currents. The cerata tips are bright white in hawaiian species, unlike
other species around the world that are cream-colored.
They are armed
with stinging capsules obtained second-hand from the food (hydroids) it feeds
on. Its scientific name, exopata, means "much desired"
referring to its beautiful appearance.
