This is an old pic from 2003, but it’s certainly one worth seeing if you haven’t before. Here’s your money quote:
“The picture is of an Antarctic minke whale taken from the bow of a ship,” said AAD principal research scientist Dr Nick Gales. “The white bits in the photo are pieces of ice-floe, the stream of pinky colour behind the whale is a faecal plume – a.k.a. “poo” – the large circle in the water is indeed the physical eruption of the whale’s flatulence.”
Thanks for the link, Greg.
