Navanax aenigmaticus from Jamaica

October 18, 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 Navanax aenigmaticus. Dredged at 5 m depth in Thallassia. Blue spots extremely variable and may even be absent. Their favourite prey is Elysia crispata.

Best wishes,
Ross

Thanks Ross,
It's interesting to know about their liking for Elysia crisaata. Most mollusc-eating aglajids seem to prefer cephalaspidean bubble-shells, so this is an unusual food preference. It confirms Humann's (1992) report.
Best wishes
