Opisthobranch of the Week Data
Mexichromis sp. 1 is considered to be very rare on Okinawa's main island as I have seen and collected a total of three individuals. All three of the collected specimens are very similar in both color and external morphology. The consistency of external characteristics of the three specimens suggests this is perhaps an undescribed species. The above featured animal was collected from beneath Tengan Pier during a daytime SCUBA excursion; it was found in the open on the surface of silty-sand and strewn oyster shell rubble.
There are currently two described Mexichromis species known from Okinawa's main island, M. mariei and M. multituberculata. The above featured animal is one of several unknown (undescribed?) Mexichromis species found here.
