What's behind a jellyfish sting?

You may know to stay away from the odd creature,the jellyfish, because of their sting but did you ever know why? Well here how it happens. Jellyfish have long sometimes flowy tentacles and each tentacle is covered in thousands  of cells called cnidoblats, and inside those cells there is nematocyts that have stinging threads. When a tentacle is brushed up against any object the stinging thread uncoils inside the nematocyts causing the stinging cells to shoot out  and firing venom. This venom is designed to paralyze the jellyfishes victim the type of venom is called neurotoxin.
