And lungfish, being related to the ancestors of all tetrapods,or four-limbed vertebrates, are equipped with true lungs.They’ll actually drown if they’re kept underwater too long.Fish have thin, permeable skin that allows for essential compounds to diffuse into and out of their bodies while they’re underwater.But this works against them on land as their bodily moisture diffuses into the air.To dodge dehydration, mudskippers roll in the mud like puppies.
