Ercolania coerulea from Hong Kong

From: Kathe R. Jensen

Dear Bill,
I am submitting another scanned slide of a Hong Kong sacoglossan. This is Ercolania coerulea. The specimen was collected on Dictyosphaeria cavernosa at Bluff Head on April 23, 1989. I have no notes on the size of the animal, but my guess is that it was about 10 mm.

Ercolania coerulea feeds on Dictyosphaeria and lays its egg masses on this alga. The egg masses are often more visible, because the eggs are white, than the slugs, which are very well camouflaged and sometimes hiding on the underside of algal clumps.

Locality:  Bluff Head, Hong Kong, South China Sea. Depth: shallow subtidal. Length: ca. 10 mm. 23 April 1989. rocky shore. Photographer: Kathe Jensen

Best wishes,
Kathe

Dear Kathe,
This certainly looks quite like the animal I found in Tanzania [message #6580], also on Dictyosphaeria.
Best wishes,
Bill Rudman
