Hydrothermalism : an extraordinary life at the bottom of the oceans

This 3rd video in a series of 3 dedicated to the oceans deals with hydrothermalism and the consequences of climate change.

And yes, there is life in the ocean depths, even though there is no light there.

The oceanographer Diana Ruiz Pino will tell us about the benthic fauna that exists in the deep sediments of the ocean. And yes, another form of life exists for many recently discovered species such as worms (as « riftia Â»), shrimps, hydrothermalist crabs, giant clams (nearly 30 cm) as well as hydrothermal lycodes or even psychropotes semperiana.

The oceanographer, Dr Diana RUIZ-PINO, member of the IPCC (Intergovernmental Panel on Climate Change) and research-professor at Sorbonne University, met in one of the laboratories where she does her researches, Laboratory of Oceanography and Climate, Experimentations and Digital Approaches (LOCEAN), we will talk about viruses that are associated with bacteria and of course have a purpose.

We will also see the consequences of our capital development: climate change, climate migrants 

Can we really make an ecological transition?

And listen to Diana RUIZ-PINO until the end, she will deliver powerful advice on living in harmony with nature.


  1. Definition of hydrothermalism + chemiotropic organism,
  2. Life also exists where there is no light,

  5. Viruses are associated with bacteria,
  6. What about climate change in all of this ?,
  7. What the IPCC has allowed,
  8. Climate migrants,
