Navanax eating Aplysia

September 17, 2005
From: Brad Bartczak

In my Marine Biology class we were able to get a Navanax to eat an Aplysia, problem is this only happened once. I was wondering what the eating habits were, such as how often and how much.
Thank you,

Dear Brad,
A lot depends on the size of the Navanax and the size of its prey. I don'yt know off hand whetjer anyone has researched that very thoroughly. There are some nice studies on what they eat and how they catch their food which I list on the species Fact Sheet but I don't think any go into great detail. have a look at the other messages about Navanax on the Forum for futher information.

One article which whcih would be useful and easy to get hold of in California is:
 Paine, R.T. (1963) Food Recognition and Predation on Opisthobranchs by Navanax inermis. The Veliger, 6(1): 1-9.

The Veliger is a scientific journal published in California so your local library, or museum or university should have a copy.

Best wishes,
Bill Rudman
