A common bottlenose dolphin (Tursiops truncatus). 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).
Oceanic dolphins are fast swimmers in comparison to seals who typically cruise at 11–27 km/h (7–17 mph); the orca, in comparison, can travel at speeds of up to 55.5 km/h (34.5 mph). The fusing of the neck vertebrae, while increasing stability when swimming at high speeds, decreases flexibility, which means they are unable to turn their heads.
Common dolphin are medium-sized dolphins; adults range between 1.9 and 2.5 m (6.2 and 8.2 ft) long, and can weigh between 80–235 kg (176–518 lb), although the range between 80–150 kg (180–330 lb) is more common. [7] Males are generally longer and heavier. [7] The color pattern on the body is unusual.
Bottlenose dolphins can live for more than 40 years. Females typically live 5–10 years longer than males, with some females exceeding 60 years. [38] [39] [40] This extreme age is rare and less than 2% of all Bottlenose dolphins will live longer than 60 years. [41] Bottlenose dolphins can jump to a height of 6 metres (20 feet) in the air.

The Irrawaddy dolphin is a slow swimmer, but swimming speeds of 20–25 kilometres per hour (12–16 mph) were reported when dolphins were being chased in a boat. [11] In a year, females can sometimes swim as fast as average of 45 km, males can swim up to average of 100 km. [12]: 2
About 300 of the mammals swim in Charleston’s waters. About 400 people help count the population each year. Here’s how you can help dolphins off South Carolina’s coast - and learn more about ...
River dolphins are slow swimmers in comparison to oceanic dolphins, which can travel at speeds up to 35 miles per hour (56 km/h); the tucuxi can only travel at about 14 miles per hour (23 km/h). [26] Unlike other cetaceans, their neck vertebrae are not fused together, meaning they have greater flexibility than other non-terrestrial aquatic ...
You can see dolphins about 80-90% of the time on a dolphin sightseeing tour. According to Richardson, the best time to go earlier in the day to see dolphins, because the ocean waves will be calmer ...
