Many dolphins do not live to be one year old. It is a high pitched series of squeaks, that when further analyzed, does not sound like any other dolphin. A stream of tiny bubbles is released from their blowhole during the whistle. Like many animals, however, females and their pups share a maternal bond. Although the terms are often used mistakenly for one another, there are differences between dolphins and porpoises, the most striking being that porpoises have a broader, rounded beak, and spade-shaped teeth.
Dolphins have a pointed beak, conical teeth, and are generally much larger.
Adult males have been observed attacking juveniles in the wild. It is thought that this is so the female becomes more likely to mate with the male to produce his offspring, rather than focusing on the care of the infant of another male for several years. Gulf of Maine Aquarium. All rights reserved.
