A female bottlenose dolphin performing with her trainer. They are considered one of the most intelligent cetaceans. Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins.
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.

There are approximately 89 [8] living species split into two parvorders: Odontoceti or toothed whales (containing porpoises, dolphins, other predatory whales like the beluga and the sperm whale, and the poorly understood beaked whales) and the filter feeding Mysticeti or baleen whales (which includes species like the blue whale, the humpback ...
Whales have beached throughout human history, with evidence of humans salvaging from stranded sperm whales in southern Spain during the Upper Magdalenian era some 14,000 years before the present. [2] Some strandings can be attributed to natural and environmental factors, such as rough weather, weakness due to old age or infection, difficulty ...

Short film My Pilot, Whale (28’, 2014, directed by Alexander and Nicole Gratovsky [68]) demonstrates the possibility of interaction between humans and free-living pilot whales, offering the viewer a number of philosophical questions related to cetaceans: about their attitude to the world, what we have in common, what we — humans — can ...
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 ...
Several whale species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead, they have plates of baleen, fringe-like structures that enable them to expel the huge mouthfuls of water they take in while retaining the krill and plankton they feed on. Because their heads are enormous—making up ...
