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.
The killer whales regularly demonstrate their competence by chasing seals up shelving gravel beaches, up to the edge of the water. The pursuing whales are occasionally partially thrust out of the sea by a combination of their own impetus and retreating water, and have to wait for the next wave to re-float them and carry them back to sea.

Sperm whales have the largest brain mass of any animal on Earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males. [24] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [25] In some whales, however, it is less than half that of humans: 0.9% versus 2.1%.

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 ...
