The common bottlenose dolphin or Atlantic bottlenose dolphin (Tursiops truncatus) is one of three species of bottlenose dolphin in the genus Tursiops. While formerly known simply as the bottlenose dolphin, this term is now applied to the genus Tursiops as a whole. As considerable genetic variation has been described within this species, even between neighboring populations, many experts think additional species may be recognized and split out.
The common bottlenose dolphin is a very familiar dolphin due to the wide exposure it receives in captivity in marine parks and dolphinariums, and in movies and television programs. Common bottlenose dolphins inhabit temperate and tropical oceans throughout the world, absent only from polar waters.
Common bottlenose dolphins have a grey coloration, a short beak, a single blowhole, and a hooked dorsal fin. The bottlenose is between 2 and 4 m (6.6 and 13.1 ft) long, and weighs between 150 and 650 kg (330 and 1,430 lb). Males are generally larger and heavier than females. In most parts of the world, adult length is between 2.5 and 3.5 m (8.2 and 11.5 ft); weight ranges between 200 and 500 kg (440 and 1,100 lb). Like the other bottlenose... Wikipedia →

Possible
About 20% of wildlife watchers report a Bottlenose Dolphin sighting in Galápagos Islands on a given day, based on 190 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 12 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a Bottlenose Dolphin in Galápagos Islands on a given day, against about 10% in April–May, August and October, the lowest months. That is one of Galápagos Islands's driest months, with almost no rain against 50 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Bottlenose Dolphin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 17
Of the 17 parks where we can rate Bottlenose Dolphin sightings, Galápagos Islands ranks 9th at about 20%. The best odds are in Bahía de Loreto National Park (Mexico, about 40%), Sian Ka'an Biosphere Reserve (Mexico, about 40%) and Fiordland National Park (New Zealand, about 40%). All parks ranked.
Same family: Delphinidae
The closest relatives of the Bottlenose Dolphin that you can see in Galápagos Islands (family Delphinidae, Oceanic Dolphins) are Killer Whale (about 10%), Common Dolphin (about 10%) and Short-finned Pilot Whale (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bottlenose Dolphin is recorded against all the mammals logged in Galápagos Islands (190 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
