How big is a bottlenose dolphin?


The bottlenose dolphin is one of the most common and well-known species of dolphin. They’re majestic creatures that are incredibly acrobatic and agile in the water. It’s particularly impressive because of their size – bottlenose dolphins are quite big animals. But how big do they get? In this article, we’ll find out how big a bottlenose dolphin is and a few other interesting facts about these incredible marine mammals.

How big is a bottlenose dolphin?

The bottlenose dolphin is a prevalent marine mammal that’s found all over the world. An adult bottlenose dolphin generally ranges between 7 and 12 feet in length and weighs between 150 to 200 kilograms. The largest individual ever caught weighed nearly 650 kilograms pounds!

Most dolphins in captivity are housed at aquariums or marine theme parks like SeaWorld, which have space constraints that prevent them from keeping dolphins of this size because they require large tanks with deep pools.

How big are newborn bottlenose dolphins?

Bottlenose dolphins have a gestation period that lasts an average of 12 months, with the calves being born between the months of June and August. Newborn bottlenose dolphins are between 2.5 and 5 feet in length and weigh around 15 kilograms at birth. These newborns are born with a greyish colour that gradually changes over their first year of life to become their adult white colouration. The new calf also has a white belly, which turns black as it ages.

Bottlenose dolphins are intelligent

Bottlenose dolphins are the most common and well-known species of dolphin. They live in all oceans, from the tropics to the poles, but they are most often found in shallow coastal waters near land. Bottlenose dolphins are one of the most popular species of dolphins in captivity, and because of this, people have learned a lot about their behaviour and biology over time.

Although there is no doubt that bottlenose dolphins are highly intelligent creatures, it’s difficult to say exactly how smart they are compared to other animals like humans or apes because scientists don’t have a standardized test for measuring intelligence across different species (though some studies do exist). Nonetheless, based on what we do know about bottlenose dolphins’ behaviour patterns as well as their intelligence level relative to other animals such as chimpanzees and elephants (both known for being very smart), it seems safe enough to say that they’re comparable if not superior when it comes down who has more brain power between the two groups–and perhaps even better than both combined!


A bottlenose dolphin’s belly is lighter in colour than its back, which is blue-grey or grey-brown. In addition, this species has a distinctive “beak”-like snout, which is used for echolocation and feeding. Bottlenose dolphins are generally found in warm coastal waters throughout the world.
