Within the publish right here I described how, on 25 November 2013, we had seen two Orcas off Dondra Head in Sri Lanka whereas heading out to see Blue Whales. I continued:

Then issues bought much more fascinating. A fellow traveller on the Naturetrek tour whale-watching extension despatched us a nonetheless {photograph} which confirmed the orcas pushing what gave the impression to be some type of dolphin with a brownish coloration across the base of a beak.

After I enlarged one on display screen there was the orca and in entrance of it, the beaked whale. The podium of the latter could be seen clearly.

Right here is the {photograph} from the closely cropped model to the complete body:

I’ve amended the unique article.
