Dirona aurantia from British Columbia

October 23, 2003
From: Bruce Wight

Note added December 2006: This species is now known as Dirona pellucida Volodchenko, 1941.

Dear Bill,
Johanna and I were up at the Northern end of Vancouver Island the first week of October diving around Port Hardy and Browning Pass. This was our first time diving in Canada. The water was 48 degrees F and the visibility was averaging around 60 feet. Many new nudibranchs for us, two species of Dirona, two species of Acanthodoris, Tochuina tetraquetra, and Flabellina verrucosa. I am sending some of the images of the nudibranchs from the trip hope you enjoy them. This one is ofDirona aurantia.

If you ever go up to the Vancouver area, try the Nautilus Explorer it is a great boat and you get plenty of diving in.
Take care,
Bruce Wight
