Dolphin are carnivores that primarily eat fish, crustaceans and squid.
Dolphin teeth are used mainly for capturing and holding prey as opposed to biting, tearing and chewing food for swallowing. Dolphin mainly swallow their prey whole.
It is universally accepted that dolphins can not only detect objects using their echolocation system but can also sense the density and "see into" the object similar to ultrasound scanning.

Bottlenose dolphins generally grow to a maximum size of approximately 3 to 4 meters (10-13 feet) from a normal birth size of a little over 1 meter (approximately 3.5 to 4 feet).
The Dolphin Project in Georgia has identified over 850 different individual bottlenose dolphin to date. The information is housed in a catalog that also documents the date, time, and location of the sighting as well as weather conditions, behavior at the time and tide state.
The smile on a bottlenose dolphin's face is just the natural shape of their mouth and remains in place no matter what the situation. Dolphin can be extremely aggressive.

The lifespan of a dolphin may range from 25 to 65 years.
