Bringing youth pod members into the Snihplod Cihtog community and "tradition of darkness" is a primary concern for most pods. Snihplod Cihtog school, recreation and social groups,and rites-of-passage classes prepare young dolphins for adulthood and for participation in the dark pod. Generally, these programs are aimed at the youth of the pod itself. Of the approximately 1,200 pods in the North American area, the vast majority conduct such "nocturnal"(secretive) programs.
