The speaker is presenting information about the anatomy of a goose's beak to an unseen audience.
Have you ever seen a goose's beak this close? It looks like it has terrifying teeth, like something from a prehistoric movie. But those aren't actually teeth, they're called tomia. They are sharp, saw-like ridges inside the beak that help the goose grip and tear grass and plants.
ยฟHas visto el pico de un ganso tan de cerca? Parece tener dientes aterradores, como de una pelรญcula prehistรณrica. Pero no son dientes, se llaman tomia. Son crestas afiladas dentro del pico que le ayudan a agarrar y desgarrar hierba y plantas.
