Today I want to write about a very big and interesting fish, the arapaima.
Here are five interesting facts about them:
- These huge fish can grow up to 4.5 metres long, making them one of the largest freshwater fish in the world.
- Arapaimas are very unusual fish because they have a special swim bladder that enables them to gulp air from the surface. They live in very dirty water that doesn’t have much oxygen in it, so they come up to breathe air every 5-15 minutes.
- They are carnivores, using their large mouths to catch fish and even birds from the surface of the water. They have a bony tongue that helps them crush and chew their food.
- They are mouth brooders, which means that they protect their babies in their mouths until they are large enough to look after themselves.
- Arapaimas are found in the Amazon and Orinoco Rivers of South America. They have also been introduced to some rivers in Asia and are farmed in the United States. Because they breathe on the surface, they are easy to catch and have been overfished in many areas, which means that their numbers are dropping.
I hope that you found these facts interesting and learned something new.
Are there any other interesting facts that you would like to share about arapaimas?
