Sina, the maiden of the Samoan coconut-origin myth Sina ma le Tuna ('Sina and the Eel'): she keeps an eel (Tuna, a transformed Fijian king who loves her) that, when slain, bids her bury its head, from which the first coconut tree grows — the three marks on the husked nut being the eel's eyes and mouth. Treated as a mortal woman (the Samoan Sina of this tale; cognate with the pan-Polynesian Sina/Hina). No kin is attested in this myth-cycle — see SOLITARY flag. Documented by Turner and Krämer (secondary).
