Cumanotus beaumonti burrowing and swimming

April 20, 2010
From: Dominique Horst

Dear Bill,

This is my final message about Cumanotus beaumonti - at least for the present [see #23522; #23523; #23524]. They burrow into the sand when danger is coming and appear to stay buried during the day except when mating. At night they were in the Tubularia.

I can confirm that they swim well. I've made short video that show it. Unfortunately photo do not show this sequence correctly.

Locality: Cagnes, 8 m, France, Mediterranean sea, 17/04/2010, sand. Photographer: Dominique Horst.

Kind regards,
Dominique

Dear Dom,

Bernard Picton suggested this species might be adapted to a burrowing existence, and this fits well with your observations. Thanks again for this interesting set of messages
