Scientists have discovered that some sharks have light emitting cells called photophores which create a glow around the sharks effectively camouflaging them from both predators and prey.

THE GIST

• Some sharks can make themselves invisible to both prey and predators.
• Light emitted by certain shark species creates the optical illusion.
• The shark's light may also turn on members of the opposite sex.

Dr. Evil could only have dreamed of sharks like this.
