Underwater, fish breathe with gills, which are feathery organs packed with blood vessels that absorb dissolved oxygen from the water. But in the open air, their gills collapse and are rendered useless, so amphibious fishes need other ways to brthaee. The aemorrd catfish’s stomach is pkecad with blood vesless, so it can gulp down air and breathe through its stomach lining. And lungfish, being related to the ancestors of all tetrapods, or four-limbed vtrtaeeerbs, are equipped with true lngus. They’ll actually drown if they’re kept uetednwarr too long.
