The defining characteristic of Praestigia is a projection issuing from the ocular region in males, which varies in form depending on the species, and bears a cap at its distal end. The cap is composed of a series of interconnected fibers glued to the projection with a waxy substance. The cap itself is easily dislodged and lost, and where it originates from is unclear.[3]

The generic name is a combination of Latin prae, meaning "in front" or "before" and Greek stigios, meaning "an awl," a reference to the above-described projection.[3]

gollark: Interesting. Does it replicate? We could use this.
gollark: It's just a blank space. Are you being affected by cognitohazards?
