No one who went to school in the ’80s and ’90s can forget the poor legless frogs — helpless victims of pollution spewed out in callous disregard for the welfare of the planet.

As it turns out . . .

Around the world, frogs are found with missing or misshaped limbs, a striking deformity that many researchers believe is caused by chemical pollution.

However, tests on frogs and toads have revealed a more natural, benign cause.

The deformed frogs are actually victims of the predatory habits of dragonfly nymphs, which eat the legs of tadpoles.
