Feeding behaviour of Navanax aenigmaticus

May 14, 2002
From: Alicia Hermosillo

Dear Dr. Rudman,
I wanted to run by you something I saw Monday May 6th during a night dive at Playa Mismaloya, Bahia de Banderas. A small Navanax aenigmaticus (12 mm at 23 feet deep) swallowed a smaller Navanax aenigmaticus (7 mm) almost fully only to spit it out a little later. Both animals carried on their ways like nothing had happened.

Has anyone out there seen something like this??

Dear Ali,
I don't know of any studies on the biology of N. aenigmaticus but there are quite a number of studies on the closely related N. inermis which I have listed on that page. Also have a look at Ernie Hartt's earlier message on cannibalism in N. inermis.
Best wishes,
Bill Rudman
