Yes, jellyfish can kill humans if they are big enough. If it just a wee lad than it will only sting.
Also, the most dangerous jellyfish is called the Australian box jellyfish, the venom is the most deadly in the animal kingdom, it has caused at least 5.568 recorded deaths since 1954. Each tentacle has about 500,000 cnidocytes, harpoon-shaped needles that inject venom into the victim.
No. Jellyfish use their stinging power to ward off predators and capture food. Unlike some bees, which do die after stinging, the jellyfish's nematocysts (it's stingers) are not directly connected to it's gut. That is the reason certain bee species die after stinging; they literally gut themselves in the act of protecting the hive and queen.
Humans have bones, jellyfish don't. Jellyfish are see through, humans aren't. Jellyfish will evaporate in the sun, humans won't. Jellyfish live under water, humans don't. Jellyfish have stinging tentacles, humans don't. Humans have different organs than jellyfish and allot more.
