Find out what is known – and yet to be discovered – about the marine life of the abyss, and how a fish called the bristlemouth has grabbed the crown for “most numerous vertebrate on Earth” from the chicken.

Plus, the menace of America’s Cascadia fault, which has the potential to unleash a devastating magnitude 9 earthquake.
