Regarding Andrea Steffen's earlier post:
I have been working on Canadian Arctic belugas for three decades and I have never seen lesions as severe as the ones she shows on http://www.pottwale.de/belugaskin. Belugas often have small pox-like lesions, about the size of a sliver dollar, but I personally have not seen such large lesions in the Churchill River belugas or elsewhere in their world range. I am told that similar lesions have been seen in the Saint-Lawrence, but rarely.
Anyway, I enquired with veterinary pathologists that are familiar with cetacean skin diseases, and the consensus so far is that, without a skin sample of one of the lesions, it is impossible to say what microbe is at fault. The lesions could be a severe case skin herpes, pox, Lacoziosis (aka Lobo), or something related.
Dr Daniel Martineau (DVM, Professor Université de Montréal) has kindly volunteered a list of relevant papers. PDFs are downloadable from the link:

Thanks to Andrea for her report. We will try to get samples if the opportunity arises. But, upon close inspection of your pictures, I think that the photos you have may be of a single animal taken at different angles. So I wonder how prevalent this really is and if indeed such an opportunity will present itself.

Subject: [MARMAM] Subject:Belugaskin Virus in Hudson River Churchill ( Andrea Steffen )
On Belugas of the Churchill river estuary, Manitoba, Canada we saw some animals with a lot of skin damages. In the websites: http://www.medvet.umontreal.ca/pathologie_microbiologie/beluga/anglais/virus_ang.asp <http://www.medvet.umontreal.ca/pathologie_microbiologie/beluga/anglais/virus_ang.asp>
we found a report about herpes like virus found on Belugas in the St. Lawrence estuary.
We were wondering, whether the skin marks of these Churchill Belugas caused of the same virus or could it have other reasons?
