Shane Gibson, Ngowiyu Guumoy Wi (night hunting)Acrylic on canvas 127 x 132 x 3 cm Hunting for Ngowiya (sea turtle) at night is a cultural practice we follow, and only those with a trained eye can see when the turtles swim beneath the surface. If you know what to look for, you might spot the shape or silhouette of the turtle and the Guumoy (Phosphorous) glowing on their backs.
