Golden Jellyfish

Description

This photo exhibits hundreds of golden jellyfish swimming in Jellyfish Lake. The lake is a 30-metre-deep basin of seawater, linked to the lagoon only by cracks in the limestone, and its golden jellies are a subspecies found in no other lake. They live with algae that turn sunlight into sugar, and each day they swim about a kilometre across the lake, east in the morning and west in the afternoon, keeping to the light and away from the shadowed edge, where a jelly-eating anemone waits.
