The scientific name for the striped dolphin is Stenella coeruleoalba.
According to some marine biologists that have studied dolphins, the life span of a dolphin is up to 20 years old.
The hole on the top of the dolphin is the blowhole. Dolphins breathe through their blowhole.
People sometimes use the word dolphin and porpoise interchangeably. However this is a mistake, as dolphins and porpoises are in fact different animals.
Dolphins make noise using a special part of their anatomy called nasal air sacs.
