Off the coast of Western Australia, marine biologists have observed sperm whales displaying cunning strategies when defending themselves against attacks by killer whales. Whales reportedly release large fecal bubbles to deter predators channel ABC News Australia.
Scientists say that sperm whales resort to a rare method called “defensive defecation”. At first, researchers thought the dark substance in the water was blood, but it later turned out to be feces. Since the diet of this whale species consists mostly of squid, its feces have a reddish tint.
Biologists noted that sperm whales not only throw the contents of their intestines into the water, but also send sewage clouds towards the killer whales with their tail blows.
The fecal attack was successful and the orcas had to swim away to find clean water.
Experts explained that killer whales usually do not attack sperm whales due to the difference in size – sperm whales reach a length of 20 meters and weigh up to 50 tons, while the average size of a killer whale is 6-8 meters and its weight is 20 meters. two to 10 tons.
