Okenia? from Gulf of Mexico

February 14, 2004
From: Kelly Hooper

Hi Bill,
Thanks for your comments on our Cerberilla. Here is a second animal from our fisheries monitoring program in NW Florida. It was caught in trawls at depths between 2.6 and 4.1 m. The bottom in this area I believe is sand. Species were caught on Jan. 8 and Jan. 12, 2004. The area is the Apalachicola Bay, an estuary protected by barrier islands.

This one, possibly a Polycera, was only about 10 mm long. It looks like P. hummi but it does not have the blue and yellow bands along the rhinophores. We have since caught other specimens and I have not seen the bands on them either. They do however have some yellow dots along the lower mantle. I hope that helps. Let me know if you have any other questions.

Dear Kelly,
You may have seen the message I posted yesterday on Polycera aurisla and P. hummi. Your animal looks a bit like both of those but in general shape it looks more to me like a goniodorid such as Okenia or Goniodoris. Perhaps if you have other photos of it which show a bit more detail I could make a better stab at identifying it, but I suspect it may be necessary to have a look at its anatomy to be sure.
Best wishes
