Noocan ah meelaha xusullada dheer hal meel oo ka baxo marka kaliya lagama maarmaan.

Sida for cuntada, xoolaha saaraysa waa bahal dhabta ah. Waxay u ugaadhsadaan inta biyo, maxaa yeelay, element this - gurigooda. Sida ay ugaadhsadaan ay doortaan kalluunka yaraan fudutahay: capelin, cunna, kalluun huruud, kalluun kala horjeeda iyo wixii la mid ah.
