Repeated breaches tire the animal, so less of the body clears the water each time. [9] Ultimately, the reasons for breaching are unknown; however, there is evidence to support a range of hypotheses. Whales are more likely to breach when they are in groups, suggesting that it is a non-verbal signal to other group members during social behaviour.

[43] Chatham Island, New Zealand: 230 195 35 2022 About 230 pilot whales beached themselves on the west coast of Tasmania, exactly two years to the day of another mass stranding in the same area.

OneWhale, one of the organisations involved in Hvaldimir's care and observations, stated that other captive and human-conditioned beluga whales from around the world could be rescued and potentially joined with Hvaldimir, with the whales possibly being released further north to the waters off Svalbard, where a group of wild belugas is known to ...

Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts their feeding and can cause mass strandings. [2] Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey.
New research shows how marine mammals ignore the rules of biology to thrive in the world's coldest waters
