On the afternoon of 12 Oct 2015, I received a text message from Toby Lineaweaver (Woods Hole) containing a photograph of an unknown animal he found washed up on the beach of Devil's Foot Island in Woods Hole, MA. The photo's show a soft-bodied, dark purple, bilaterally symetrical invertebrate with lobular extensions or folds over what I assumed was the dorsal side. He sent several photos (included). I noted the anterior (head) end with what appeared to be appendages in the shape of fleshy horns. My guess from the photo's was a sea hare (Aplysia). I asked Toby to bring the animal back from the island if he could. He left it in his dory at the Woods Hole Yacht Club where I found it laying in a pool of water. It was much larger than I assumed from the photos - at least 10 inches in length and a kilo or so in weight. Purple fluid appeared to be exuding from it and,based on the swirling of the water and this fluid, I realized the animal was still alive. I placed it in a bucket and transported it to the Marine Resources Center. I placed the bucket in a sea table with flowing ambient sea water. Scott Bennett reported to me this morning that it expired during the night and was disposed of. I based my tentative identification on the fact that some previous reports exist through the Gray Museum at Yale (http://discover.odai.yale.edu/ydc/Search/Results?lookfor=Aplysia+fasciata&submit=Find&type=allfields) and the general description of a very dark and large Aplasia. Following an exchange here, I retrieved the corpse and dissected out the internal shell and photographed it to add to the record.
