16. Bilateral Symmetry

This is a picture of a lobster, which represents bilateral symmetry. Bilateral symmetry is a body form that can be divided into two mirror images. If a line is drawn down the middle of a lobster from its head to its tail, then each side of the lobster will be roughly the same. Lobsters have bilateral symmetry because most mobile animals, which ranges from lobsters to birds to humans, have bilateral symmetry to help them with coordination.
