Explanation:

The Santals also have totemistic clans, known as pari. These 12 clans are divided into two ranks: 7 senior and 5 junior. The senior clans are believed to originate from the 7 sons and daughters of the first man and woman, and in order of seniority they are: Hansda (goose), Murmu (Nilgae), Marndi (Ischaemum rugosum), Kisku (kingfisher), Soren (Pleiades), Hembrom (betel palm) and Tudu (owl). The junior clans are Baskey (stale rice), Besra (falcon), Caure (lizard), Pauria (pigeon) and Donker. Members of a senior clan do not marry members of a junior clan, and there are some forbidden marriages as well, such as between Marndi and Kisku. In addition, Besras are sometimes treated differently due to their perceived low status, but other than the context of marriage, they play no role in social life. The clans also avoid harming their clan totem, lest evil befall them.
