The Selcuk-Efes Camel Wrestling Festival in Turkey

The annual Selcuk Efes Camel Wrestling Festival is a fixture on the Turkish sporting calendar and, increasingly, a major draw for tourists to the country's southern Aegean coast. First practised by Turkic tribes more than 2,400 years ago, the sport angers animal-welfare groups but is big business for organisers.

Spectators who travel to the event or watch the hundreds of clips that circulate online are treated to a peculiar spectacle. In one fight, a knobbly-kneed warrior twists and turns while a female camel entices the males with her long eyelashes. Foamy saliva often spurts from the mouths of excited males – a potential hazard for spectators who get too close.
