Surprising facts about blue whales
Blue whales are mammals. They have lungs like us. Hence to get oxygen, they come above the surface of water. Inhale oxygen,then go inside water. For exhale,they again come above water surface. Blue whales have the life span about 80- 90 years.
But they wont live upto that many years. Reason is surprising. The reason is ships. When they come above water surface for inhaling oxygen, there will be ships travelling on sea. They are hitting the blue whales. They die because of this friction bound wounds.
