The "Sea-snake" is played by the natives of Murray Island, Torres Straits, they call it Pagi = a Sea-snake. It is described by Rivers and Haddon (p. 152, Fig. 9). Partington (pl. 341, 3) gives a drawing of a finished pattern from Torres Straits, preserved in the British Museum (A. C. Haddon Collection) and labelled "cat's-cradle in the form of a water snake (garé)."

This figure is interesting because the Second and Third movements are unlike anything we find in other figures, and also because the majority of the movements are done on the left hand only, instead of being done simultaneously on both hands. Of course the final figure must be unsymmetrical.
