Scientists think they have resolved one of the most controversial environmental issues of the past decade: the curious case of the missing frogs’ legs.
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.
