Jorunna rubescens from Anilao, The Philippines

February 17, 2005
From: Paul Osmond

Hi Bill,

I had meant to send you these images right before the site went quiet, so I never got round to it.

This large speciman of Jorunna rubescens was busy laying an egg spiral on this coral head on a deeper reed in off of Anilao, The Philippines on one of the 'Sombrero Island' dive sites.

We came upon this individual basically towards the end of the laying and observed it for several minutes as it finshed and then moved off.

Locality:  Anilao, Batangas, The Philippines. Depth: 25 m. Length: 15 cms. 15 March 2004. Coral Reef, White Sand Bottom. Photographer: Paul T. Osmond

After all the little species, this is a big nudibranch - this one in the 15cm range.

Enjoy,
Paul

Dear Paul,
Thanks for the photo. This is certainly a strange looking animal and I must say I still find it difficult to think of it as a species of Jorunna. I am glad to see the egg ribbon you photographed is the same as ones I have seen the species laying in Tanzania. It's always good to get some confirmatory evidence.
Best wishes,
Bill Rudman
