Hi everybody,
a nice Diatom from the Northsee.
I'm not a specialist,and a member of a french forum found the ID:Biddulphia aurita.
best regards.

Bon Jour Olivier,

Another nice photo- Merci!

The name Biddulphia aurita is no longer valid. The "new " name is Odontella aurita ( name is from 1832!).

if you are interested in marine micro-algae, a great guide book with lots of photos - in French - is:

Guide d'identification du phytoplancton marin de l'estuaire et du golfe du saint-laurent.

Authors: Lyse Berard-Thierriault, Michel Poulin et Luci Bosse

Published CNRC, Ottawa 1999
ISBN 0-660-96057-5

It is relatively inexpensive - I think that I ordered it directly from the CNRC website.

OK it relates to Canadian waters, but most algae are widely distributed.

Bon chance
Au revoir
Brian
