Bottlenose dolphins can live for more than 40 years. Females typically live 5–10 years longer than males, with some females exceeding 60 years. [37] [38] [39] This extreme age is rare and less than 2% of all Bottlenose dolphins will live longer than 60 years. [40] Bottlenose dolphins can jump to a height of 6 metres (20 feet) in the air.

They have exceptionally sophisticated echolocation abilities, detecting the location and characteristics of prey and other objects in the water by emitting clicks and listening for echoes, [45] as do other members of the dolphin family.
