Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

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%.

Regina Haug, founder of OneWhale, told NBC News that Hvaldimir was believed to be approximately 15 years old, relatively young given that beluga whales can live 60 to 70 years in the wild.
Just this month some 200 pilot whales stranded themselves on. There's a tiny tip of sand at the very northern tip of New Zealand's southern island called Farewell Spit. It is lovely and remote.
“The most dreaded bit of ocean on the globe – and rightly so,” Alfred Lansing wrote of explorer Ernest Shackleton’s 1916 voyage across it in a small lifeboat. It is, of course, the Drake ...

It includes recordings of belugas, narwhals, orca, and bearded seals. Sounds of the Earth: Humpback Whales (Oreade Music) was released on CD in 1999.
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 ...
