Gastric Brooding Frog
Vampire Bird-Eating Frog
Called the Khorat big-mouthed frog, this was found in MekongThailand. It catches and eats small birds using fangs that come out from its jawbone. This vampire frog also feeds on insects and other frogs. This “opportunistic eater” lies waiting from its prey and jumps on them.
