A dolphin is an aquatic mammal in the clade Odontoceti (toothed whale).Dolphins belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and possibly extinct Lipotidae (baiji or Chinese river dolphin).
Female dolphins reach sexual maturity at around ten years old, while males mature at around 13 years old. They usually mate from the end of summer to autumn, and calves are born after a gestation period of eleven months. The mother stays with her calf until it can find food for itself, usually when it reaches 3–4 years old. [10]
An hourglass dolphin has 26 to 34 teeth in their upper jaw and 27 to 35 teeth in their lower jaw. Like all species of dolphins, they use echolocation to find food.

[141] In some parts of the world, such as Taiji (in Japan) and the Faroe Islands, dolphins are traditionally considered food, and are killed in harpoon or ...
Scientists trying to understand the hunting behaviors of bottlenose dolphins have come up with a unique solution: fit them with video cameras.
Cetacea (/ s ɪ ˈ t eɪ ʃ ə /; from Latin cetus 'whale', from Ancient Greek κῆτος () 'huge fish, sea monster') [3] is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises.

They have streamlined and graceful bodies, a single blowhole and a short and defined beak, possessing between 39 and 50 teeth per row.
