Plans for ocean floor mining are moving forward globally -- especially around thermal vents that create deposits of metals like gold, silver, copper, manganese, cobalt, and zinc -- but humans have explored less than 1% of the deep sea, so it’s fair to say that we really have no idea what’s at risk.

On this episode we speak with deep sea biologist Dr. Diva Amon about what we do -- and don’t -- know about biodiversity at the bottom of the ocean.

Raised on the shores of Trinidad & Tobago, Dr. Amon's fascination with what lies below the surface has taken her on journeys to great depths, and she shares insights and glimpses of amazing creatures gained there.

Here’s more about this episode’s top news:

• Eight ape species, including Tapanuli orangutan, make first appearance on list of most endangered primates
