Species Account:

        Berthella sp. 2 is considered to be very rare on Okinawa's main island as the above featured animal is the only one collected. The animal was collected from beneath a slab of coral rubble in an area of mixed sand and coral rubble during a mid-morning SCUBA excursion.

        This small attractive pleurobranch is quite similar in appearance to B. stellata, but lacks the white cross-like mark in the center of the mantle and symmetrical white diagonal marks seen in most individuals of that species.

        This animal is one of several known and unknown Berthella species from Okinawan waters; links to these are as follows:
