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.

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 ...
A researcher fires a biopsy dart at an orca.The dart will remove a small piece of the whale's skin and bounce harmlessly off the animal. Cetology (from Greek κῆτος, kētos, "whale"; and -λογία, -logia) or whalelore (also known as whaleology) is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific ...
Images released by OneWhale, a non-profit organization dedicated to the protection of Hvaldimir, show the beluga whale after they say it had been shot dead.
WHOI scientist Michael Moore's book is about how consumers play a role and have responsibility for right whale's possible extinction.
Borrowing an analogy from publishing and bookbinding, he divides whales into three "books", called the Folio Whale (largest), Octavo Whale and the Duodecimo Whale (smaller), represented respectively by the sperm whale, the orca (which he calls the grampus) and the porpoise. Each such book is then divided into "chapters" representing a separate ...
Baleen whales - a group that includes the blue whale, the largest animal in Earth's history - use a larynx, or voice box, anatomically modified to enable underwater vocalization, researchers said ...
