The vaquita (/ v ə ˈ k iː t ə / və-KEE-tə; Phocoena sinus) is a species of porpoise endemic to the northern end of the Gulf of California in Baja California, Mexico. Reaching a maximum body length of 150 cm (4.9 ft) (females) or 140 cm (4.6 ft) (males), it is the smallest of all living cetaceans .
As the name implies, they tend to be found in the open seas, unlike the river dolphins, although a few species such as the Irrawaddy dolphin are coastal or riverine. The Delphinidae are characterized by having distinct beaks (unlike the Phocoenidae), two or more fused cervical vertebrae and 20 or more pairs of teeth in their upper jaws.
Also, fewer than ten pilot whales, Amazon river dolphins, Risso's dolphins, spinner dolphins, or tucuxi are in captivity. Two unusual and very rare hybrid dolphins, known as wolphins , are kept at the Sea Life Park in Hawaii , which is a cross between a bottlenose dolphin and a false killer whale.
The International Whaling Commission released its first ever extinction alert to raise awareness surrounding the decreasing vaquita porpoise population.

“The Delphinoidea has a diverse taxonomy, with over 35 mammalia taxas. This includes the species of genus Odobenocetops and Odobenus rosmarus [2]. While also having two types of genus, they also have individual genomes with about 9 species across the three main families of the Delphinoidea.
