But to a type of Australian snake, this rude behavior is a matter of life and death. The snake, called a floodplain death adder , eats two types of frogs that are hard to stomach. The frogs produce chemicals to defend them from predators . One of these species, the Dahl's frog, can kill a snake that tries to eat it. The other species, the marbled frog, is less dangerous but still tough to eat. When attacked, _ produces a glue like substance. Leaves and branches get caught up in this material, making a big sticky mess that gets in the way of anything trying to swallow it. A marbled frog can even get stuck on the head of an attacking snake. Both frogs have good defense methods. But the floodplain death adder knows how to get around each of them. Floodplain death adders quickly strike these frogs, using their poisonous teeth to inject poison.

That's because both the Dahl's frog's protective toxin and the marbled frog's glue break down over time. After a while, the frog toxin is no longer poisonous and the glue is no longer sticky. The two substances break down at different rates, and floodplain death adders seem to know the difference, And adder waits for a different length of time depending on the species of frog it just struck. The stickiness of the marbled frog glue decreased by as much as two-thirds after just 10 minutes. And that's just about how long an adder waits before eating a marbled frog. On the other hand, the snakes wait for about 40 minutes before eating a Dahl's frog. That's enough time for the frog's toxin to break down into harmless substances. But even a quick strike gives a taste of the Dahl frog's toxin. After striking such a frog, a floodplain death adder thrashes around and lies on its back with its mouth open, It's like the snake has just had a...
