Favorinus mirabilis Baba, 1955

Favorinus mirabilis comes in a variety of color forms as seen in the photos below. The species is not very common, but specimens have been found at Kwajalein, Enewetak, and Utirik Atolls, usually under rocks by day or crawling on algae or cave walls at night. Sizes have ranged from 6 to 8mm. Like its cousin Favorinus japonicus, F. mirabilis eats the eggs of other opisthobranchs.

These two individuals moved away from the egg ribbon they were eating when exposed to light.

The two specimens below were found eating the egg mass of a dorid nudibranch.
