The dolphins (Delphinidae), also called oceanic dolphins to distinguish them from the platanistoids or river dolphins, are a very heterogeneous odontocete family of cetaceans, comprising 34 species.
They measure between 2 and 9 meters long, with fusiform body and large head, elongated snout and only a blowhole on the top of the head (breathing hole that many marine animals have as contact of air or water with their internal respiratory system). They are strict carnivores.
They are among the most intelligent species that inhabit the planet. They are relatively close to the coasts and often interact with the human being.
Like other cetaceans, dolphins use sounds, dance and jumping to communicate, orient themselves and reach their prey; They also use echolocation. Nowadays, the main threats to which they are exposed are anthropic
