“Journey to the Microcosmos: Peritrich Ciliates--Masters of Long-Range Snacking” explores peritrich ciliates, single-celled eukaryotic microorganisms that use cilia to create water currents and capture food. The video introduces key microbiology concepts including cilia, microtubules, protozoans, peristome structure, Vorticella, sessile and free-swimming forms, trophont and telotroch life stages, and convergent evolution. It also examines how these organisms attach to surfaces, feed efficiently at a distance, and interact with other organisms through epibiosis or, in some cases, harmful infection. With historical context from Antonie van Leeuwenhoek’s early observations, this microscopy-based science resource supports life science curricula focused on cells, organism structure and function, microorganisms, adaptation, and ecological relationships. Part of the "Journey to the Microcosmos" series.
