Re: Line of slugs and aggregations

Concerning message #21008:

Dear Bill and everyone,

I was in Poe Beach last week end and I saw the aplysid aggregations. There were 5 to 8 by m2 on a long distance. Probably it's Stylocheilus striatus but I don't see stripes. It was not easy to take picture with the waves and sun but I send you 3 of them. We could see purple ink in the back of a stressed animal.

Locality: Poe Beach, Bourail, 1 m, New Caledonia, Pacific Ocean, 11 November 2007, Sand and algae. Length: 5 cm. Photographer: Jean-François Hervé.


Thank you for your help.

Dear Jean-François,

It's always a bit of a nuisance when a species doesn't have the character which give the species its name, but the dark 'striae' or lines are not always found in Stylocheilus striatus. Your photo alongside gives us a good view of the gill in the cavity formed by the parapodia. Have a look at my drawing in an earlier message [#7872] to get some idea of the parts.

Best wishes,
Bill Rudman
