I really like pink river dolphins because they are harmless to humans and they are pink. They live in the Amazon River of Brazil. Isn’t pink a weird color of a dolphin?
Well they are pink because capillaries are close to the top of their skin. Sometimes they can be pale blue or albino (also known as white). There are 5 species of fresh water dolphins. Pink river dolphins are the largest species of river dolphins. They can grow to be 9 feet long and can weigh up to 300 pounds. They can also live to be 30 years old.
The Amazon keeps getting more polluted over the years. This is why they are heading towards extinction.
Their eyes are small and they don’t rely on eye sight to live. They use echolocation to fend for themselves. They have a large bump on there head. The bump on their head is not a brain it is a lens used for echolocation. They are incredible swimmers because they have a very flexible backbone. They can also preform 180 degrees head turns. Calves may be born in the middle of July or September.
What a cool animal. There are a lot of animals that are endangered because of pollutions. Maybe you could help them by not polluting the water.
