Students research each animal and make bracket predictions about which species might emerge victorious in a fictitious battle environment. Factors include temperament, weaponry, armor, body mass, running speed, fight style, physiology, and motivation. Scientific literature is cited to substantiate likely outcomes.
Through information embedded in the bout descriptions, participants learn about interspecies interactions, ecological context, how natural selection has shaped adaptations and conservation management of endangered species.
Battles play out on Twitter, with this year's winner announced on Wednesday, March 31.
