Summary

The abnormal animal featured here is a tadpole with two heads. In order to explain how it got that way, the chapter desccribes how the axes of the body are established in the embryo. This leads to a discussion of axes in conjoined twins and symmetry planes in various parts of the body, plus a three-eyed frog.
