Toothy Grin


Crocodile, Osaka Aquarium. How do you know it's a croc and not an alligator? An alligator's lower teeth fit under the top jaw, the top jaw overlapping over the lower jaw. A croc's jaws are both about the same size, allowing some of their lower teeth to extend out over the upper jaw, particularly the large fourth tooth.
