Dear Bill,
Here are some photos of Navanax inermis for the Forum. They were taken at West Anacapa Island, Channel Islands National Park, California, in 8-10 m., 5 July 2001. The animals were both about 5cm long.
Best wishes,
Daniel Geiger.

Geiger, D., 2001 (Jul 27) Some photos of Navanax inermis. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/4927![](/images/g4756a.jpg)
Dear Daniel,
I am glad to get some good photos of this wonderful animal. When I studied the anatomy of the aglajids as a graduate student I was fascinated by the size of this enormous animal. Growing to over 20cm, it is so much larger than most of its relatives. I have included a close-up of the head showing the clear patches through which the small black eyes can be seen. These eyes, as of course you will know, are very primitive light sensing organs, unable to form images and of no value in hunting its prey.
Best wishes,
Bill Rudman
