उत्तर
- Jellyfish are a coelenterate that has cnidoblasts bearing tentacles.
- These cnidoblasts inject toxins to paralyse the prey at the time of feeding.
- When jellyfish come in contact with our bodies, this toxin is released, causing a reaction to our skin.
Therefore, our body gets irritated when we come in contact with jellyfish.
