Bottlenose Dolphin

Habitat: Coasts, estuaries, lagoons, reef passes, and open ocean — the great generalist of the dolphin family

Distribuição: Worldwide in temperate and tropical seas; the encounters divers plan around are at Rangiroa's pass, Egypt's northern Red Sea reefs, and the Azores

Comportamento: Big-brained, socially fluid, and boldly investigative. Most wild bottlenose ignore divers after a look; a famous few populations choose interaction — Rangiroa's pass residents approach divers mid-drift, holding eye contact and sometimes soliciting a slow parallel swim. Bow-riding is the species' oldest human game.

Dieta: Fish and squid, hunted cooperatively with tactics invented locally — mud rings, strand-feeding, sponge tools in one Australian bay

Tamanho: normalmente cerca de 2.8 m; documentado até 3.8 m (body length; coastal animals run smaller than offshore ones, and the Indo-Pacific bottlenose (T. aduncus) is smaller again).

Let the dolphins initiate and end contact, no touching or grabbing even when solicited, no feeding ever, and keep swim-with activities to regulated programs. At Rangiroa, follow the guides' drift line and let the residents come.

Least Concern globally; local coastal populations face bycatch, pollution, and disturbance, and the species' charisma sustains both good regulation and bad captivity — choose wild, managed encounters.
