It’s sad to see the demise of the poor pufferfish, but you have to admit its impressive what will fit through a frogfish’s mouth. They have evolved to be supreme ambush predators capable of eating animals twice their size thanks to their hyper elastic stomachs and protruding jaws. In fact, their jaws create a strong suction when they strike, drawing in their prey. Frogfish literally inhale their food.
