Yes, betta fish have a fascinating adaptation that allows them to breathe air. Unlike most other fish species, bettas possess a specialized organ called the labyrinth organ. This organ is located in their gills and enables them to extract oxygen directly from the air.
While bettas primarily rely on their gills to extract oxygen from the water like other fish, they also have the ability to gulp air from the surface. They swim up to the water’s surface, take in air, and process it through the labyrinth organ. This unique adaptation allows bettas to supplement their oxygen intake and survive in low-oxygen conditions or stagnant water.
The labyrinth organ of betta fish acts as a sort of “lung” and allows them to breathe atmospheric air. This ability is particularly advantageous in their natural habitats, such as shallow rice paddies, ponds, and slow-moving streams, where oxygen levels can fluctuate. However, it’s important to note that bettas still require a proper aquatic environment with clean water and adequate oxygenation for their overall health and well-being.
