Manfred Keller Blue Velvet Headshield Slug (Chelidonura varians) - Puerto Galera (Philippines)

Manfred Keller It's mimicking a flatworm, but which one?

Ron Silver This is a headshield slug which is an opisthobranch rather than a nudibranch.

Reed Nescher Here is one in the Russell Group of the Solomon Islands, they seem very common in the Solomon Islands.

Franca Wermuth-Vezzoli Chelidonura varians laying eggs. Bonbon, Romblon Island, Philippines

Blogie Robillo Fascinating. They lay their eggs from up front?

Franca Wermuth-Vezzoli I only just found it in the sea slug forum:

Franca Wermuth-Vezzoli http://www.seaslugforum.net/find/20031 "The white specks are eggs, and the animals are in the process of making their bubble-shaped egg mass which they anchor in the sand with a long mucous thread"

Kati Burg I've seen that also. Looks very interesting. http://www.nudipixel.net/photo/00027492/location/romblon/

Blogie Robillo Chelidonura varians. Depth 5m, length 2.5cm, Samal Island, Philippines.

Patrik Good Chelidonura varians, Seaway SW Wall, 40mm, 1 metres, 16/4/2012 in darkness on sandy substrate, 25 degree water. The deep clear blue contrasting to the black is just fascinating. Another Algajidae found at the Seaway. Found Chelidonura fulvipunctata on same dive.

Patrik Good Is this a temperate species? It is not on nudibranch.com.au.

Gary Cobb No it is not! We just have not found it here yet. Bum!

Thomas Philipp I dont know which one. Photo taken back in 2008 an Bali / Tulamben Area with Canon Powershot A620

Astrid Scharf chelidonura varians?

Ron Silver Yes

Reed Nescher Another from the same location in the Solomon islands.... https://scontent-a-sjc.xx.fbcdn.net/hphotos-frc3/1237615_10201365370568960_1852821737_n.jpg

Anne Diver This is not a flatworm, it is a head shield slug, it looks like Philinopsis gardineri

Reed Nescher Sorry, I thought the Head shield had a curl at the head? I have pictures in the same area of the Head shield, but this seemed different? Thank you.....

Anne Diver Reed, do a Google Image search on Philinopsis gardineri and see if it matches your animal, and see what you think. Without seeing the animal I certainly could be wrong....

Reed Nescher I didn't see the "Flukes" as shown in the images in the search? It was very flat with no apparent "Flukes" so that is why I though Flat Worm....
