Concerning message #21623:

Hello everyone. I am new to the Forum, thou I have used the information on the site before.

But..today we have spotted a very unusual nudibranch. I believe it is Ceratosoma tenue. But it was very huge - about 18 - 20 cm! We are wandering if that can be connected with the age of the animal or thay can grow up to this size? Very very rare animal here.

Locality: Hurghada, 10m, Egypt, Red Sea, 9 June 2008, sandy bottom close to reef. Length: 18 - 20 cm. Photographer: Alicja Polaczek.

Sunny regards,
Dorota

Dear Dorota,

This is certainly a species of Ceratosoma, but is C. trilobatum. As you have noticed, the shape of these animals seems very strange, especially if you haven't seen one before.

Best wishes,
Bill Rudman
