Bottlenose Dolphin

The Bottlenose Dolphin (Delphinus Truncatus) is an uplifted cetacean species which weighs an average of 300 kg. It can reach a length of just over 4 meters. Colouration varies considerably, is usually dark grey on the back and lighter grey on the flanks, but it can be bluish-grey, brownish-grey, or even nearly black, and is often darker on the back from the rostrum to behind the dorsal fin. This is called countershading and is a form of camouflage. Older dolphins sometimes have a few spots. The rostrum contains 18 to 29 teeth on each side of each jaw.

Bottlenose dolphins can live for more than 40 years. Females typically live 5–10 years longer than males, with some females exceeding 60 years.
