In 1998–1999, Harvard researchers published their DNA identifications of samples of whale meat they obtained in the Japanese market, and found that mingled among the presumably legal (i.e. minke whale meat) was a sizeable proportion of dolphin and porpoise meats, and instances of endangered species such as fin whale and humpback whale.

On average, an orca eats 227 kilograms (500 lb) each day. [71] While salmon are usually hunted by an individual whale or a small group, herring are often caught using carousel feeding: the orcas force the herring into a tight ball by releasing bursts of bubbles or flashing their white undersides. They then slap the ball with their tail flukes ...
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
By comparison, the modern sperm whale length measures on average 11 m (36 ft) for females and 16 m (52 ft) for males, [18] with some males reaching up to 20.7 m (68 ft) long. [19] [20] [21] The large size was probably an anti-predator adaptation, and allowed it to feed on larger prey.
Spermaceti is taken from the spermaceti organ (yellow) and junk (orange) within the sperm whale's head. Raw spermaceti is liquid within the head of the sperm whale, and is said to have a smell similar to raw milk. [8] It is composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides. [9]
Sperm whales, Sharma said, also use a two-level combination of features to form codas, and codas are then sequenced together as the whales communicate. The lower level has similarities to letters ...
