26. Hydractinia, the minimal jellyfish

The 26th chapter of the “Inhabitants of the microworld” series is called “Hydractinia, the minimal jellyfish”.

Floating in the water of the sea lives a huge amount of living beings, most of them invisible to the naked eye, that form what we know as plankton. Among them are organisms as delicate as the transparent jellyfish Hydractinia. Hydractinia is a colonial marine hydrozoa with two well differentiated reproductive phases, polyp and jellyfish. This jellyfish, measuring less than half a millimeter in diameter, was one of the first organisms used as a model to study stem cells and cell reprogramming.

This is the 26th chapter of a series that will bring to us a video per day during this confinement forced by COVID-19.

We hope that you enjoy this initiative, which gives access to a documentary series for free to the world, and you share it with everyone you think will possibly be interested.
