African lungfish have two lungs,and can breathe air. This is a vital feature,since they live in flood plains in waterways that often dry up. Lungfish secretes a thin layer of mucus around itself that dries into a cocoon. It can live out of water in this cocoon for up to a year,breathing through its lungs until rains refill its waterway
