Description

A blind predator?!?

Leanchoilia is a four-eyed arachnomorph arthropod known from Cambrian deposits of the Burgess Shale in Canada and the Chengjiang biota of China.
Prominent are large, frontal appendages with long extended whiplike extensions.
Since Leanchoilia was apparently blind (no eye-like structures have yet been found), these appendages helped locate food and keep Leanchoilia informed about its surroundings.
