Doto koenneckeri feeding, laying eggs and predation ?

April 14, 2010
From: Dominique Horst

Hi Bill,

These all should be Doto koenneckeri.
All specimens were living and feeding on the hydroid Aglaophenia sp.
One is laying eggs.

The systematic presence of Caprella sp suggests that may be they are interested in eating the Doto eggs, but I have no confirmation about this predation?

Locality: Banyuls, 8m, France, Mediterranean sea, 27 March 2010. Length: 5 mm. Photographer: Dominique Horst.

Kind regards,
Dominique

Thanks Dom,

The purplish marks on your animals certainly fit Bernard Picton's description as 'comma-like' so I would agree with your identification.

As I noted in an earlier message [#20296] caprellids appear to co-exist with at least some hydroid dwelling nudibranchs.

Best wishes,
Bill Rudman
