3 - Extra-Legged Frogs

from Part I - Frogs

Summary

The abnormal animal featured here is a frog with extra legs. It grew the extra legs because it was infected with a parasite when it was a tadpole, and the parasite caused the growing leg to split into pieces. A similar thing happens in a fly that also has extra legs, except that there there's no parasite, just necrosis.
