Air-breathing Memes

When you thought evolution was done with fish, lungfish and bettas said "hold my oxygen." These absolute legends decided that gills were too mainstream and went full bimodal respiration mode. Lungfish literally have functional lungs and can survive out of water during droughts by burrowing into mud and breathing air like some kind of aquatic doomsday prepper. Bettas, on the other hand, have a labyrinth organ that lets them gulp air from the surface—which is why they can survive in those tiny bowls (though please don't keep them there, they deserve better). Both are flexing their evolutionary advantages like they're in an epic handshake of respiratory superiority. Meanwhile, regular fish are just sitting there with their basic gills wondering what went wrong with their life choices.
