Dear Bill:
Here is another sea slug from Jamaica. As I said in my first message, all specimens were collected from St. Ann's Bay, Jamaica, West Indies. Photo: R. Gundersen.

Here is Dendrodoris krebsii. Found under rocks on shoreline. Can shed outer edge of mantle.

Best wishes,
Ross

Dear Ross,
I am glad you mentioned that this species 'Can shed outer edge of mantle' as it alerted me to the fact that you have two different species in this message.

The upper photo is a species of Discodoris, almost certainly what is called Discodoris evelinae but may well be the same as the Indo-West Pacific species Discodoris lilacina which is well-known fpr his habit of breaking off the mantle skirt when disturbed. One of the other names for D. lilacina is Discodoris fragilis in recognition of this behaviour. [See autotomy Page.]

The lower photo is almost certainly a species of Dendrodoris, and as Valdes and his colleagues have suggested, D. krebsii is the best name at present for this animal.

Best wishes,
