The Ravenous Sea Tiger

I watched a program a few years back and saw footage about the sea tiger sea slug, but can find no information on the web about this striking representative. Any information on where I may learn more about the sea tiger would be greatly appreciated.

Dear Josh,
I think you are probably referring to Roboastra tigris which is found in the Gulf of California. It can grow to 12 inches (30 cm) in length and feeds on other nudibranchs which it grasps with its radular teeth and swallows whole. I am afraid I don't have a photo of this interesting animal but with luck, someone reading this will be kind enough to send some photos to the Forum and some further information. One reference is:

•Farmer, W.M. 1978. Tambja and Roboastra (Mollusca, Opisthobranchia) from the Gulf of California and the Galapagos Islands. The Veliger, 20: 375-385.

Best wishes,
Bill Rudman.
