## Resource

Did you know that there are over 60 species of shark who are luminous? In this episode, we learn all about the sharks who light up the darkness of the deep sea. How are they able to produce their own light? And why have they evolved the ability to glow? We are joined by Professor Jerome Mallefet, an expert in bioluminescence who has studied some of the most fantastical species on earth, including a shark with lightsabers on its back - the velvet belly lanternshark - and the largest known luminous vertebrate, the kitefin shark.
