Dolphins are aquatic mammals which live in most seas around the world. Like all mammals they are viviparous and breathe through their lungs. They can be submerged up to 300 meters deep and can hold their breath for almost 25 minutes!
The average length of a dolphin is around 4 and a half meters, which is the length of a normal car and they weigh about 300 kilos. Dolphins are carnivorous, their main source of food is based on crustaceans, fish, squid and octopus, though during their first year of life a baby feeds on its mother’s milk.
Dolphins tend to live in groups and are extremely intelligent. But do you know what the dolphin’s biggest problem is? Humans because of their hunting and contaminating the waters which is causing many dolphins to die.
We must look after our ocean and seas and like that dolphins as well as all living creatures will be a lot happier.
