Bottlenose Dolphin

Tursiops truncatus

Bottlenose dolphin | Tursiope

The bottlenose dolphin is the dolphin par excellence, the best known because it is the species that man has managed to make live in a controlled environment (dolphinariums and water parks). It is a typical coastal species and therefore it is not rare to see it near ports or observe it from the beaches. It has a vast acoustic repertoire and it is thought that each individual has its own "signature whistle", a unique vocal imprint that allows you to distinguish it from other specimens. They are also known for their ability to perform stunts out of the water: tail spinning (walking backwards out of the water standing on the caudal fin), breaching (diving out of the water).
Caratteristiche: corpo affusolato e robusto di colore grigio scuro. Il rostro è lungo e tozzo, da qui il nome “naso a bottiglia”. La pinna dorsale è a forma di falce e durante l’età può ricoprirsi di cicatrici o segni che vengono usati per identificare i singoli individui.
