Video shows 'bubblegum coral' at world's deepest trench
A US-funded research expedition to the Marianas region of the Pacific Ocean has produced a new video of marine life, featuring 'bubblegum coral'. Found at a depth of around 522 metres, the bright pink coral was seen hosting an "oasis" of living species, including a worm-like brittle star, strands of sponge, algae and a crab among others.
