How Many Teeth Do Dolphins Have?

The number of teeth a dolphin has varies by species, however it is estimated that some species may have as many as 250 teeth.

For example the Atlantic bottlenose dolphin has between 80 – 100 teeth, while the short-beaked common dolphin has as many as 240 teeth.

Despite having teeth not all dolphins use their teeth for chewing or breaking apart their prey.

Some species only use their teeth to grab onto their prey and will consume their food whole, while other species don’t appear to have any real use for their teeth at all.
