Do tortoises have a mating ritual? The (courtship) ritual begins with the male walking in circles and bobbing his head. The female tortoise will approach the male, which results in the male bobbing his head more vigorously. Once the female has approached, the male will bite at her legs and shell. | National Zoological Garden
