How do nematocysts worke?

Nematocysts are specialized cells found in cnidarians, such as jellyfish and sea anemones, that serve for捕食 and defense. When triggered by touch or chemical signals, the nematocyst rapidly ejects a coiled thread that can inject toxins into prey or predators. This mechanism allows the organism to immobilize or deter threats, enabling its survival and feeding. The process is remarkably fast, often occurring in less than a millisecond.
