Lungfish are a unique group of lobe-finned fish known for their ability to breathe air using lungs, in addition to gills. This adaptation allows them to survive in oxygen-poor waters and even out of water for extended periods. They are found in Africa, South America, and Australia. Think of them as fish that can almost walk on land. They're like the amphibians of the fish world. It allows them to thrive in harsh environments.
