New Species from the Mekong Delta

Khorat Big-Mouthed Frog
Found thus far only on three remote Thai islands, the Khorat big-mouthed frog is an opportunistic predator. A patient hunter, it lies in wait for its prey in streams, where it strikes birds, insects and other frogs with fangs that protrude from its bottom jawbone. Unlike many other species of frog, among Khorat big-mouthed frogs, males are larger than females, and they often fight one another.
