The 15m blue whale has to pay the price of its life for swimming in the wrong territory of the hungry killer whales off the coast of Western Australia.
The only blue whale defends itself against a large pod of killer whales. Video: Whale watching in Western Australia.
Jemma Sharp, owner of the Whale Watch Western Australia travel agency, observed the tension between blue whales and orcas from a distance of just a few meters. In addition to Sharp, 40 tourists on board also have the opportunity to watch the intense battle. According to him, the blue whale just accidentally swam into the orca’s feeding and breeding area.
Blue whales, humpback whales and minke whales that swim north are more likely to encounter groups of hungry killer whales when entering Bremer Bay. Adult blue whales always have the experience of staying away from orcas throughout the journey.
While directing visitors in the sea, Sharp saw 5 killer whales with up to 75 groups concentrated in the sea around the blue whales. Some of them jumped out of the water, ran towards the whale and jumped high, exposing most of their bodies. For the next 3 hours, the orcas cooperated with each other, attacking continuously, exhausting the blue whale. They also trick the whale into swimming on one side so that it cannot breathe down the gutter.
However, the above method is not effective because blue whales are too strong. Finally, the killer whale bites the target’s tail to distract attention. The entire pod of orcas gathered on top of the whale so that it could not fight back and eventually it suffocated. They are quick to tear the prey apart, even seabirds, sharks and pilot whales all have a role.
The blue whale is the largest mammal in the world and is in the threatened category. They can reach a length of 30 m and weigh more than 170 tons. The food of the blue whale is mainly crustaceans, small mollusks, so to fill the stomach, they just have to eat a lot. According to scientists’ estimates, a blue whale swallows up to 3 tons of mollusks a day.
The killer whale (Orcinus orca) is a widely distributed predator in the world’s oceans. When ripe they can weigh up to 6 tons, 7 to 10 m long. They are found at the top of the food chain and often hunt in groups. The orca’s prey is extremely rich, including fish, penguins, seals, sea lions, rays, squid, seabirds, even whales and sharks.
