Lungfishes are sarcopterygian fish that can breathe air (and in some species are obligate air-breathers), and have limb-like appendages instead of fins. There are six living species known; four in Africa, and one each in South America and Australia. Most of their skeleton is made out of cartilage, and electro receptors can be seen as tiny holes under their jaw.

The modern lungfishes have a number of larval features, which suggest paedomorphosis. They have probably the largest genome among the vertebrates.

They all have an elongate body, four limbs, and a single rear fin.
