However, interactions do sometimes become spectacular; in October 2022, a rare ...
The bisected head of a dolphin: The melon is just above the upper jaw. Three-dimensional models of various odontocete melons based on CT scans. The melon is a mass of adipose tissue found in the foreheads of all toothed whales. [1] [2] It focuses and modulates the animal's vocalizations and acts as a sound lens.
A large number of whales visiting the waters off New England included an uncommon sighting of an orca eating a tuna and an unusually large group of an endangered species of whale, scientists said ...
Baleen whales have two blowholes positioned in a V-shape, while toothed whales have only one blowhole. [6] The blowhole of a sperm whale , a toothed whale, is located left of centre in the frontal area of the snout, and is actually its left nostril, while the right nostril lacks an opening to the surface and its nasal passage is otherwise well ...
In coastal waters near Chile in 2023, a massive female killer whale walloped the much smaller dolphin, sending it flying out of the water. Within minutes, the unequal battle was over and the orca ...

The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean.
