III INTERESTING FACTS ABOUT DOLPHINS

1 Unlike any other mammals, dolphin babies are

born tail first And a mother dolphin will stay a

calf for two to three years

2 A dolphin’s long nose helps them kill sharks

3 They breath through a special opening on their

heads called a “blowhole” When dolphins are

relaxed or underwater, their blowholes are closed

4 Dolphins have been clocked at speeds of 26.3

km/hr, which they maintained for about 1500

meters, leaping constantly

5 Dolphins, like cows, have two stomachs – one

for storing food and one for digesting it
