TIL the most common zebra species named themselves quagga

Preschool lied to me: zebras make sounds!

At least six different calls have been documented for the plains zebra. One is its distinctive, high-pitched, contact call (commonly called "barking") heard as "a-ha, a-ha, a-ha" or "kwa-ha, kaw-ha, ha, ha" also transcribed as "kwahaah", or "oug-ga". The species name quagga is derived from the Khoikhoi word for "zebra" and is onomatopoeic for its call.
