Chromodoris geometrica laying eggs

September 3, 2007
From: Kenneth Yong


Dear Bill,

Here are 2 photos of Chromodoris geometrica. The 1st shows it laying eggs. Nearby, scattered on the almost vertical surface of a boulder were other C. geometrica (I counted a total of 16), with the largest group made up of 3 animals (photo 2).

Locality: Lang Tengah Island, Nibong Karang divesite, 15 m, Terengganu, Malaysia, South China Sea, 09 July 2007, on vertical face of boulder. Length: 6-7 cm. Photographer: Kenneth Yong.

Cordially,
Kenneth

Dear Kenneth,

This species is one of those reported to have extra-capsular yolk so its nice to get another photo to confirm that. Can you check out your other photos of this species to see if you have any of it on a dark purplish brown sponge - or any sponge for that matter. When I see or hear of aggregations of a species like this, I always suspect their food sponge must be nearby

Best wishes,
Bill Rudman
