Nematocyst discharge is triggered by an immediate approach or a foreign stimulus. When the cell is discharged, a brand new nematocyst is created as the system in each cell can only be activated once.

The trigger mechanism of the nematocyst organelle of the stinging cnidocyte cell consists of a sensory hair and a chemical receptor. When the sensory hair is mechanically stimulated, it activates the chemical receptor, leading to the discharge of the nematocyst's venomous contents.

prey capture
When a stinging cell, also known as a cnidocyte, comes into contact with another organism, it triggers the discharge of a harpoon-like structure called a nematocyst. The nematocyst injects venom into the target, immobilizing or deterring it. This process is crucial for capturing prey or defending against predators in cnidarians such as jellyfish and sea anemones.

Nematocysts are specialized organelles found in cnidocytes of cnidarians. When triggered by physical contact or chemical stimuli, nematocysts discharge by releasing a tightly coiled tubule that penetrates the prey or predator, injecting venom. The discharge is rapid and usually irreversible, playing a crucial role in the cnidarian's defense and hunting mechanisms.
A nematocyst is a stinging cell found in the tentacles of cnidarians like jellyfish and sea anemones. When triggered, the nematocyst fires a coil-like structure that injects venom into its prey or predator, immobilizing or killing it. This mechanism is crucial for the cnidarians' ability to capture and consume food.
