Animales simples: gusanos

The video tutorial explores the diversity of worms, focusing on three major groups: flatworms, earthworms, and segmented worms. Flatworms, or tlatelmintos, have a more advanced nervous system and exhibit bilateral symmetry. Earthworms, also known as nematodes, possess a one-way digestive system. Segmented worms, or annelids, have segmented bodies and a closed circulatory system. The video also highlights the unique characteristics of leeches, a type of annelid that feeds on blood.
