29. Micropredator: Didinium

The 29th chapter of the “Inhabitants of the microworld” series is called “Micropredator: Didinium”.

Formed by a single cell, Didinium is one of the world’s smallest predators. This speedy and jittery microscopic swimmer is about a tenth of a millimeter long and is able to catch and engulf prey like Paramecium, three times bigger tan himself. To catch them he uses his conical “beak”of the anterior part of the cell, and the tiny stings it has inside, called trichocysts.

This is the 29th 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.
