Luckily for us the majority of our jelly's have more skrik factor than anything else. Not like the Aussies who have the infamous Box jellyfish. A sting from these ou's and you're dead in about 3 minutes. More people are killed by jellyfish each year than by sharks, with jelly's having caused at least 5,568 recorded deaths since 1954.
Even a lifeless jellyfish has the capability to sting. So careful when you go kicking 'em about on the beach. It may just have the last laugh....
As deadly as these critters can be, they're pretty rudimentary lifeforms. No brain, no lungs, no skeleton, no circulatory system. They eat and crap out the same hole - glad we evolved from the mouth/anus combo. Yuk. Some have up to 24 "eye's" but they still can't see for sh*te, basically being able to determine between light and dark. So yah, not the sharpest crayon in nature's pencil bag.
But sometimes simple is the secret to success: Jellyfish were there even before the dinosaurs existed on planet Earth. So they're real locals.
But there is one species that's immortal. The Benjamin Button of jelly's. When the Turritopsis nutricula is gatvol of being all grown up, it just reverts back to polyp stage and starts again. Pretty damn neat.
If you're wondering how the species has managed to exist for so long despite having such short lifespans it's cos they breed like crazy. A single jellyfish can release as much as 45,000 eggs each day! So the saying should rather be "they breed like jellyfish" instead of "they breed like rabbits!"
Also, if a jellyfish is cut in two, the pieces of the jellyfish can regenerate and create two new organisms. Similarly, if a jellyfish is injured, it may clone itself and potentially produce hundreds of offspring.
They're really adaptable creatures as well. There are around four hundred dead zone areas in the oceans of the world where only jellyfish can survive and no other life form. So guessing they still gonna be floating about long after we're gone.
OK, so a group of fish is called a school; a bunch of dolphins is a pod, so what's a whole lotta jelly's called?
A smack. So reckon we can just South African-ise it and call it a "klap"!?
If you do end up getting stung, the best remedy is to run hot water over the area - hot as you can bear without burning yourself. Otherwise some vinegar might help too. Pee'ing on it? Debatable.
Personally, the only jelly I like is the one with custard and ice-cream....
