The ninth chapter of the “Inhabitants of the microworld” series is called “Lethal softness”.
Hydra is a polyp, as anemones, although it does not live in the sea but in fresh water lakes and ponds. It has a delicate aspect and, usually, is not larger than a few millimetres. But its aparent delicacy is delusory. Hydra is a powerful predator of small aquatic animals that captures by mean of the urticant cells recovering the surface of its delicate tentacles.
This is the ninth 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.
