A paramecium (Paramecium caudatum unicellular organism used as a model organism in microbiology laboratories) is poisoned by a predator. In response, the paramecium relays protective filament species called “trichocysts” that serve to help it escape in these cases.
But the infection was too big and the paramecium will gradually die. What will immediately attract ciliated cells (Litonotus) who will devour the unfortunate cell.
