Lovely Headshield Slug

Chelidonura amoena


"Headshield slug with rounded head, 2 long tail like appendages. Colour is grey-brown, fading at sides, with a fine white punctuation and yellow tips. 5 cm. Easy to distinguish from Chekidonura inornata and other species by the fading colour pattern." Source:


Coral and reefs, sand and rubble. Indo-Pacific.


Pictures 1-2 are of a pair mating. Pictures 3-5 are of one of the slugs crawling away after mating. Probably disturbed it :-) Depth of about 6 m. Twin Rocks, Anilao, Batangas, Philippines

Congrats Eric, this great underwater series has been chosen spotting of the day!

The sea slug is herbivorous, feeding on plankton and decaying matter on the ocean floor, and grazing on the rocks and coral reefs for algae.
