| The Atlantic
bottlenose dolphins have a long, beaklike snout, a dorsal
fin, and sharp teeth. They are toothed whales and have
one blowhole.
Dolphins breathe air at the surface of the
water through a single
blowhole located near the top of the head.
They need to breathe about every 2 minutes, but can hold their
breath for several minutes. Their blow is a
single, explosive cloud.
These dolphins live in groups called pods. The bottlenose dolphin grows to be at most
12 feet long, sometimes weighing more than
1,400 pounds. Bottlenose dolphins have a
life span of about 25 years. |
