Keri Wilk, 30, a Canadian photographer, said he and a group of divers were observing sperm whales off the island of Dominica when they found themselves "at ground zero of the most epic bowel movement that I've ever witnessed."
"When we were sufficiently confused/blinded by poop, it burst out of the poop ball faster than I've ever seen a whale move.
"This is essentially the equivalent of an octopus squirting ink, and as strange as it sounds, this was one of the coolest things I've ever seen underwater. And no, we didn't do anything to stress the animal, and all government permit rules were followed precisely with an extremely experienced guide and boat captain."
