Concerning message #19975:

Hi Bill,

I guess this is Eubranchus farrani. For the id, I supposed the main characteristic for this species is the form of the cerata ?
Because colour variations of this animal make the identification not easy ...
I should say this one is "classical" as compared the specimen from Sylvie.

Locality: Antibes Cape, 11 m, France, Mediterranean sea, 25 April 2009. Length: 5 mm

Kind regards,
Dominique

Dear Dom,

Some of these species with considerable colour variation are difficult to define - at least by using their colour pattern. In this case,the inflated cerata are fairly characteristic, and so is the presence of the orange subterminal bands - but that doesn't help with some of the colour variations we have on the Forum where the orange band is absent. I guess some species are not easy to define, and to identify them often requires a good local knowledge.

The aeolids are often quite difficult to identify externally not only at the species level but at higher levels as well. Often we need to study the internal anatomy before we can be sure. That means that identifying species only from living animals and photos requires a good memory, a lot of books or/and access to a local expert.

Best wishes,
Bill Rudman
