Tiny sharks in South East Asia have helped scientists to understand the origins of glowing shark species.
A number of deep-dwelling sharks have special light-emitting organs on their undersides that allow them to glow.
A study of pygmy sharks now suggests the ability to control the trick evolved from a shallow water ancestor.
Dr Julien Claes from the Catholic University of Louvain in Belgium led the research.
He said: "bioluminescence remains one of the most mysterious areas of shark biology."
