Say hello to Saccorhytus coronarius, a truly fugly ancestor of yours from about half a billion years ago.

Meiofaunal deuterostomes from the basal Cambrian of Shaanxi (China)

This little guy (about a millimeter) is an ancestor to vertebrates. Embarrassingly for the family tree, the digestive tract, which starts with a clearly oversized mouth, terminates with… the mouth. Bleah.
