  • About 30 are likely still alive, according to the local authority.
  • So far, 50 whales have been returned to deep water. “We will continue working to release as many animals as possible,” says official Nic Deka.

Just a few miles from remote Macquarie Bay, another 200 stranded long-finned pilot whales have been discovered. More than 200 animals were found in this bay on Monday. An on-site biologist talks about the largest stranding to occur on the island off Australia. You can hear how animals still alive call to each other in their distress.

Long-finned pilot whales are very social animals. They communicate using an extensive repertoire of whistles and live in groups, called schools, with an average of 20 animals. When there is a lot of food, there are seasonal associations of hundreds of animals.

The groups follow the individual lead animals. After this they swim themselves in waters that are too shallow, where they can no longer orient themselves. Most of the animals die in such strandings. During rescue operations, animals that have been taken to deep water often swim back to their companions who are still stranded.

Long-finned pilot whales, also known as pilot whales, can grow up to six meters long and weigh three tons. The species was heavily hunted for a long time. Since then, the number of animals has recovered somewhat. In the southern hemisphere they are found in all oceans, in the northern hemisphere in the Atlantic. Some specimens have also been discovered in the North and Baltic seas.

Most of them cannot be reached by boat. The rescue operation will probably take a few days. It is one of the most difficult rescue operations compared to previous mass strandings in the region. Helpers focus on animals with the best chance of survival. The whales beach quite frequently in Tasmania. However, in general, far fewer animals are affected. A smaller group of sperm whales had recently washed ashore in the area.
