Chromodoris coi from Malaysia (2)

From: Kheong Sann Chan

Here are some more photos from Pulau Dayang off the east coast of west Malaysia.

The last few are of the Chromodoris coi and there were a fair number of them around. Unfortunately my camera's batteries were dying at the end of the dive and could not shoot as many as I would have liked.

Location: Dayang, Pulau Lang
Date : 8 June, 2100
Depth : 15+m

Thanks Kheong,
This seems to be quite a regular find for you. perhaps it would be worth checking, next time you find it, to see if you can find which sponge(s) it feeds on. If you are lucky a photo of it on its food sponge would be very interesting. One way to check if it actually feeding or rather than just crawling past is to gently try and lift its head end and see if there is part of the animal protruding out of the mouth and attached to the sponge.
Good Luck
