dolphins
- Dolphins typically cruise at 5 to 7 miles per hour, but they have been clocked at 18 to 22 miles per hour with top speeds of 30 miles per hour.
- Traveling as much as they do, dolphins must rest some time. They don't sleep, though. They merely take cat naps at the ocean's surface for two or three minutes at a time. At night, those naps increase to seven or eight minutes.
- Dolphin calves usually born in the spring they are 2.5 to 3 feet long and 25 to 40-pounds. Feeding on its mother's milk, a calf will double in size in the first few weeks. Adult males are larger than females. The Mid-Atlantic dolphins will reach 7 to 10 feet in length and 300 to 500 pounds by their early teens.
- In captivity, dolphins have lived as long as 40 years. In the wild, though, scientists believe they only live 25 to 30 years.
