Tritoniopsis frydis from West Indies

G'Day, Bill.

While diving on Little Cayman, British West Indies (Caribbean Sea) in May 2007, I saw a Tritoniopsis frydis on a gorgonian at the dive site Mixing Bowl at a depth of about 12 meters. At the time I saw it, it was just moving off a mass of eggs, which I assume were just laid. A few days later I saw another one (lower photo ) on the same gorgonian, but the eggs were gone, presumably hatched.

Thanks Jim,

It's interesting to get some more photos of this Caribbean equivalent to the Indo-West Pacific species T. elegans. One major differnce though is that your species feeds on gorgonians while the Indo-West Pacific species feeds on leathery soft corals such as Lobophyton.

Best wishes,
