The 44th chapter of the “Inhabitants of the microworld” series is called “Roundworms”.
Nematodes, also known as “roundworms” are among the most abundant animals on Earth. They live in almost all environments, both aquatic and terrestrial, and have developed a huge diversity of life strategies. A lot of them feed on vegetables, other on bacteria and animals, and even there exist some parasitic species, like the filaria and trichina. The species Caenorhabditis elegans is one of the model organisms for different specialities related with biology, among them neurobiology. Some species, one of them appearing in the video, have a surprising reproduction in which males literally nail their spermatophores in the female (in the video you can see it marked with a white arrow).
This is the 44th 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.
