Cumanotus beaumonti from the French Mediteranean

April 20, 2010
From: Dominique Horst

Dear Bill,

I think this is Cumanotus beaumonti. Oral tentacles are visible, but not obviously on the juvenile...?
Not sure if this is any help on the debate about C. beaumonti vs C. cuenoti
The biggest was more than 20 mm long.
I have photos of feeding, food and reproduction in three following messages [#23523; #23524; #23525].

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

Thanks and kind regards,
Dominique

Dear Dom,

Information on species of Cumanotus is very welcome. Thanks for this and the other 3 messages.

Certainly the clear pictures of the oral tentacles and tentacular foot corners in your animal suggest that it is the north Atlantic C. beaumonti rather than the mediterranean C. cuenoti which was described as lacking such tentacles. It is hard to see if your juvenile has tentacles or not - I have ringed a possible oral tentacle in the little close-up. As I have discussed before it is possible that the the tentacles are not developed in juveniles and Mediterranean and Atlantic populations are one species.

Best wishes,
Bill Rudman
