Petalifera ramosa from Jamaica

October 19, 2003
From: Ross W. Gundersen

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. Most specimens were collected using a light weight dredge and photographed by R. Gundersen.

Here is Petalifera ramosa. Dredged at 1 m depth in Thallassia. Highly energetic slug which swims by coiling and uncoiling its body in response to the slightest touch.

The upper right picture fits the description of Petalifera ramosa by Marcus of Jamaican specimens.

The whole animal [lower right] fits the description of Phyllaplysia engeli from Marcus. Racemous extension of the tubercles were not observed in these specimens (36). There is another form which has reduced tubercles and meandering white lines.

Best wishes,
Ross

Thanks Ross,
Your upper right photo clearly shows the branched papillae which I had not been able to find any mention of in previous reports of the species from the Caribbean, so it certainly would seem that this is another species with a wide warm water distribution worldwide
