Sperm whales blasted a “huge darkish bubble” of poop to forestall an impending orca assault off the southern coast of Western Australia.
Scientists witnessed the intelligent protection technique unfold Tuesday (March 19) throughout a vacationer tour in Bremer Canyon, a whale-watching hotspot off the coast between Albany and Hopetoun. They described seeing a “cloud of diarrhea” permeate the water, and this hardly ever seen protection mechanism appeared to assist the sperm whale pod escape what might have been a deadly assault by not less than 30 killer whales, ABC News Australia reported.
“It is referred to as protection defecation,” Jennah Tucker, a marine biologist with Oceans Blueprint, a marine and environmental sciences analysis group, who was on the constitution boat, instructed ABC. When the animals defecate, she mentioned, they move their enormous tails via their poop to drive away or confuse attackers.
Because the occasion unfolded, onlookers observed a big, “darkish bubble” pop as much as the water’s floor. At first, they thought it was blood from one of many sperm whales, doubtlessly a small calf. However when the staff later reviewed footage of the plume, they realized it was really whale poop.
“As a result of [a] sperm whale’s food regimen consists largely of squid, they really have this actually reddish coloured poo,” she mentioned.

On this demonstration of protection defecation, the pod fashioned a circle with their heads collectively, and the whales fanned their tails in unison — forcing their excrement towards the unsuspecting orcas.
“That is referred to as a rosette, one other defensive mechanism they use after they’re below assault,” Tucker mentioned.

Tucker instructed ABC she observed that the sperm whales appeared distressed and exhausted. Nevertheless, their fecal warfare labored, and the orcas swam off looking for brisker waters. It was within the midst of this mayhem that researchers noticed the large, blobby poop bubble rise to the water’s floor.
There have been just a few documented cases of orca assaults on sperm whales, largely because of the sheer dimension differential between the 2 species.
“Sperm whales are thought-about an apex predator, and traditionally, it was thought that they have been just about resistant to killer whale assaults,” Tucker mentioned. “It is really fairly adventurous for orcas to attempt to tackle sperm whales. They’re punching above their weight.”
