From the pulsating bell to the shimmying tentacles, jellyfish have got to be some of the weirdest lifeforms our planet has to offer. Oral arms wave mindlessly around a central mouth while stinging cells puncture and poison without a thought. Not only does the jellyfish not even have to be alive for it to sting, but the stinging tentacles needn't be attached to the rest of the body at all. The futility of such endeavours is totally lost on them, as if they're more a force of nature than an animal. The sheer depth of their apparent mindlessness is quite amazing. It's like watching someone watching TV. Or, with all these reality shows, watching someone watching someone watching TV on the TV.
But no matter how strange a jellyfish may seem as it drifts in the ocean's currents, its life history is stranger still. Jellyfish really are weird from start to finish.
