Cross-Eyed Beakworm

The Cross-eyed Beakworm isn't really cross-eyed. In fact, it only has one eye. Its one eye, however, has developed a unique, elliptical, dual-pupiled eye, which also has semi-separated retinas. In order for it too look around, it has developed an eye where the retinas move instead of the eye. This has allowed them to actually have a small amount of depth perception, which in turn, allowed them to form much larger schools.
