The Fall 2010 underwater photography season has now started with the cooler weather at hand. Great seeing these beautiful sea slugs.

I don't know what this is, but is sure is pretty, looks like an ornament for the coffee table. Somehow this is not what I envision when I hear the word slug.

Derek Holzapfel on September 22, 2010

Thanks Laurel. We have 35 species of Nudibranch (sea slugs) in our waters. They are amazingly beautiful and contain some of the purest colours in nature. This one happens to have the whitest of white. :-)

What an amazing nature photographer you are! Your underwater shots are so serene and unusual. Looking forward to seeing more from you! Best wishes, pear (p.s. I'm adding you to my favorite photographers.)

Thank you so much Pear; The underwater world here is truly amazing. I had just a few minutes back, looked at your birds and others again, and had also added you to my fav's as well. regards Derek

An underwater unicorn! Gorgeous!!!!!

Derek Holzapfel on October 16, 2010

I guess from this angle it looks like a Unicorn. The "horn" is actually one of two gills that are outside of the nudibranch. Thanks Bits-n- Pieces

Hi NatureDiver, I never realised that nudibranch can be found in Canada. Always thought they are tropical animals - how uncivilized and ignorant of me! This one is real beauty!!

Anyway your picture has really excellent composition, colours and sharpness.

Best wishes from Finland, Timo

Derek Holzapfel on October 18, 2010

Thank you Timo; There are actually about 35 species of Nudibranch here in Canada. They have the purest of colours in the underwater world here. Guess you will have to bring your u/w gear over for a photo dive sometime. All the best, Derek

This is absolutely superb underwater photography, Derek! Not on;y have you captured the beauty of this sea slug, but you also have shown us tube worms feeding :)

Greetings, Amelia

And I see it is in the contest too! VOTE.

Hi Derek,

sure I would like to come out there, but I guess first I have to get used to diving at cool waters after living and diving too many years in tropical conditions, where water temperature very seldom goes below 27°C, By the way, what is the best time of the year to dive out there?

Best regards, Timo

Derek Holzapfel on October 18, 2010

Thank you Amelia, good eye on seeing the tube worms. This photo is full of life that many do not see.

Derek Holzapfel on October 18, 2010

Hi Timo; Water temp at depth is usually around 6-8C, and I only dive Sept - May. Too hot to put on a dry suit in the summer and plankton growth can limit visibility. Dive season has just started and I hope to be in the ocean each week. Of course winter storms can hamper those plans a bit too. 27C - too hot...... :-) You can see what it is like here at - I have been building a species photo database for many years now. take care, Derek

Amelia Royan on October 18, 2010

It is always amazing what can be found, even just under the surface of the water, Derek :))

tmoj on October 18, 2010

Thanks for the info Derek. I think I have to test first diving back home in Finland. If I can manage that, I might be able to dive in Canada also. The big step is stating to use dry suit..

By the way your web site is very interesting, especially I liked the story of octopus attack. Must have been scary!

All the best, Timo

Derek Holzapfel on October 19, 2010

Yes Timo, diving with a dry suit really helps but is not mandatory. The new wet suits are pretty warm.
The Octopus Attack has been my most extraordinary underwater experience. Did not think I was going to be coming back up :-)
