West African Lungfish: Custom Animal Art Trading Card

A “living fossil”, the West African lungfish have been around for nearly 400 million years. Like other fish, they have gills to extract oxygen from water, but also have primitive lungs to extract oxygen from the air. When food is scarce, an African Lungfish burrows into a muddy ground to create a safe habitat, enclose itself in a cocoon of its own mucus, then go into a hibernation-like state called “estivation”. While in this state, it digests its own muscle tissues for food, and can therefore survive dormant for a long period of time.
