Tiny sharks provide glowing clue
By Ella Davies
Reporter, BBC Nature


Scientists caught the tiny dogfish sharks off the coast of Taiwan

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."
