- Phylum Cnidaria possesses specialized nerve cells called sting cells or nematocysts.
- These cells are used to capture and stun prey such as water fleas and plankton.
- Sting cells contain toxins that can paralyze or kill their prey, making it easier for the cnidarians to consume them.
- The presence of nematocysts is a defining characteristic of the phylum Cnidaria.
Additional Information
- Cnidarians include organisms such as jellyfish, sea anemones, and corals.
- The nematocysts are located in specialized cells called cnidocytes.
- When triggered, the nematocyst ejects a coiled thread that can inject toxins into the prey.
- This mechanism is not only used for prey capture but also for defense against predators.
