Spout shapes differ among species, which facilitates identification. This is followed by inhaling fresh air into the lungs. A humpback whale's lungs can hold about 5,000 litres (1,300 US gal) of air. [4] [5] Baleen whales have two blowholes positioned in a V-shape, while toothed whales have only one blowhole. [6]
It has also been observed in larger cetaceans such as false killer whales and orca, [20] [21] although most larger Odontocetes do not seek out any form of interaction with boats. Bow-riding is the most common form of interactive behaviour with boats across a variety of smaller Odontocete species, such as dolphins in the genera Stenella and ...
Orcas also prey on larger species such as sperm whales, grey whales, humpback whales and minke whales. [ 84 ] [ 40 ] On three separate occasions in 2019 orcas were recorded to have killed blue whales off the south coast of Western Australia, including an estimated 18–22-meter (59–72 ft) individual.

A few toothed whales, such as some orcas, feed on mammals, such as pinnipeds and other whales. Toothed whales have well-developed senses – their eyesight and hearing are adapted for both air and water, and they have advanced sonar capabilities using their melon. Their hearing is so well-adapted for both air and water that some blind specimens ...
Killer whales have no predators -- except for humans. Documentaries like 'Blackfish' reveal the exploitation behind whale captivity. In the late 1960's, Famous orca Shamu was the whale who set the ...
Northern resident orcas, also known as northern resident killer whales (NRKW), are one of four separate, non-interbreeding communities of the exclusively fish-eating ecotype of orca in the northeast portion of the North Pacific Ocean.
The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark at high speed.
In terms of length, blue whales have often been compared to three school buses lined up back to back. These whales measure 90-100 feet long and are estimated to weigh from 200,000-352,000 pounds ...
