The Chukchi live in the far northeast of Siberia and refer to themselves as Luoravetlans. Like the Koryaks, they are divided into two groups. One of them lives inland, where reindeer herding is their main source of livelihood. The other part lives on the coast and hunts marine animals there. The exchange of life-essential materials between these two groups has always been of particular importance. They express their respect for nature through special rituals and seasonal reconciliation feasts.
