ome have strips. Dolphins have a well-developed sense of hearing. The auditory nerve may have 67,900 or more cochlear fibers, which is twice as many as the human. They can detect sound frequencies of less than 1kHz if they are loud enough. The dolphins sense of sight is also very good. A dolphin can see particularly well in the water. The sense of touch of a dolphin is also well developed. The dolphin has limited sense of smell.There is not a lot known about a dolphins sense of taste. They do have taste buds, though they have not been studied enough to come to any conclusions. Dolphins do show preferences toward different types of fish though.

Sometimes dolphins also follow shrimp boats to eat what was thrown overboard. Dolphins dont chew their food they just swallow it whole.

Bottle-nosed dolphins have few members, under twenty. Others species have up to thousands of members in their school. Dolphins can dive up to 1795 feet. Bottle-nosed dolphins rarely dive more than 150 feet. They can dive for up to ten minutes. They slow their heartbeat down while diving, which helps them to stay down longer. Dolphins breath threw a blowhole at the top of their head. Every two minutes they make a short, explosive inhalation and then a longer inhalation before submerging again. They exhale just before reaching the surface, which is what makes the little splash in the water. Exhaling and inhaling takes the dolphin approximately .3 seconds.
