How does a Jellyfish Sting?
Jellyfish’s tentacles include hundreds of venom containing stinging cells referred to as Cnidocytes. Jellyfish use them for cover in addition to for the seize of a prey.
Cnidocytes are mainly small compartments which home mini-needle like stingers. The stinger lies coiled below excessive osmotic stress.
Now, when there’s a set off as a result of an exterior power, the lid of the stinging cell pops open and sea water rushes in.
This forces the mini-needle like stinger to shoot out, penetrate and at last inject venom into the sufferer.
This discharge can happen in lower than one millionth of a second. That is how a Jellyfish Stings.
