dolphin math

• After feeding on mother's milk the first few weeks, calves begin eating fish at 3 to 4 months and are weaned at 12 to 18 months. Dolphins feed on all kinds of fish and crustaceans with adults eating 13 to 14 pounds of fish a day or 20 pounds or more in colder winter waters.
• In captivity, dolphins have lived as long as 40 years. In the wild, though, scientists believe they only live 25 to 30 years.
• Dolphins travel in pods of up to 15. A pod typically consists of s
• everal adult females, calves and adult males. Pods may travel together in herds of several hundred individuals. Dominance or aggression, in the form of a showing of teeth, tail smacking, jaw snapping or head butting, establishes the hierarchy in the pod.
• 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.
• Dolphins have outstanding vision in and out of the water. In the water, their eyes are protected from the sea water by mucus secreted from glands at the outer corner of the eye. Their ears, small and hard to detect, are located just behind the eyes and have no flaps or lobes. The dolphin's swimming power comes from its caudal fluke, which moves up and down instead of side-to-side like fish. The dorsal fin provides stabilization and may also regulate body heat -- a dolphin's body heat is very close to human body heat at 97.7 degrees F (36.5 degrees C)
