Species Account:
Chromodoris collingwoodi is considered to be very rare on Okinawa as I have seen and collected a total of only two individuals over a period of more than twenty years of diving here. The featured animal was found in an area of mixed sand and coral rubble, crawling on top of coral rubble. The individual collected from 60ft was also collected
from Seragaki in the same habitat, i.e., mixed sand and coral rubble, crawling on top of
coral rubble.
