Day Twenty-One: In the Moonlight

We find India at the top of the cliffs of Folkestone in South East England to meet a group of women who swim under the light of the full moon. Meanwhile. on the other side of the world in Australia, the coral of the Great Barrier Reef is spawning to coincide with the full moon. Professor Oren Levy of Marine Biology at Bar Ilan University talks us through this wonder. Credits: Presented by: India Rakusen. Producer: Ellie Sans. Assistant Producer: Jorja McAndrew.
