Nematocysts Firing

[heyeveryoneimcool]

Brutal.

[iCommenter66]

omg that shit is fast

[mahela1993]

@iCommenter66 I think it's the fasted known biological movement.

[mattu2be]

Hey, any idea where was this taken from? This is really cool!

[subasurf]

nematocyst...the bane of my existence. I'm stung on a weekly basis by bloody jellyfish when I'm surfing.

Maybe I should cover myself in mucus...

[Kg277]

Chuck Norris' wife douches with these.

[lordennis01]

that is soooo cool

[Bdawg71692]

once they shoot off are they done for? kinda like a bee sting?

[aronchai]

@Bdawg71692 Yes.

[Xaltus]

Can Jellyfish sting another Jellyfish?

X

[aronchai]

@Xaltus Yes.

[H3NDY7]

0:21 :S ouch :-(

[Scrod99]

IMMA FIRIN MAH NEMATOCYSTS BLAAAHH

[Wolfboy183]

Nature's own firearms. Imagine if they had BIG nematocysts? That would suck

[MadBear1118]

*Sobs quietly* Owie!

[tronilau]

wow!

[MrZKoll]

does anyone know the name of the barbs that are shot out? It is one of my questions for my environment class.

thanks

[Wolfboy183]

@MrZKoll the barbs shot out are nematocysts. They're pretty much like needle-containers. The cell containing the nematocyst is like a missile silo and the nematocyst is the missile. It's connected by a cable that retracts after firing. When the cell fires, it uses calcium ions to absorb water and create a lot of pressure. As the pressure builds, the hatch opens, and the nematocyst shoots out, and the cable it's hooked to uncoils.

[addeex1]

Omg I could almost feel it!! :O

[dangthatscool1]

amazing, when i saw the first volley i went "oh holy shit!"

[MesterMc]

holy shit !

[Cleric2145]

Those nematocysts fire their stingers with a force of five million G's. I kid you not.

[slk320k]

Fastest reaction in the animal kingdom apparently.

(Same firing mechanism for Chironex Fleckeri - box jelly fish)

[DigiTan000]

You've gotta be kidding me!!

[dp100eboggan]

ow!

[Airbusa319thehornet]

Nematocysts are the fastest reacting and executing organic/bodily systems in the world. Imagine getting stung by an Irukandji or other Cuboza family jellies....

[Vesania83]

this is so cool! we did this in our biology-fieldcourse just a few days ago. We cut of a bit of a Mertridium senile (don't know the name in English) and added vinegar.. it was like fireworks :D

[trickmastermonkey]

that was so awesome. I just learned about Phylum Cnidarian in my bio class earlier today

[trickmastermonkey]

oops, i mean cnidaria

[cooloriginaltwic]

Do NOT mess with Cnidaria!

[Prymer55]

i heard that those things firing is the worlds fastest metabolic reaction, next to a prayin mantis attack.

[steveobeach]

wolverine jellyfish

[biloxigator]

Nematocysts- the only weapon on planet Earth that's nastier than a prison shiv.

That's the first time I've seen these things fire close up, and I'm counting my blessings that I haven't ended up wearing a set of those from all the times I've been swimming.

[1962shawn]

OMG I GET SICK EVERY TIME I WATCH THIS its so scary

i wonder what kind of jellyfish it is

[Uthallan]

jesus, those went into me today.

[dlindeman]

excellent video

[r0ck3tsm0k3]

Boy are those things fast.

[rockingtheglam]

is there a way to copy this video? it would

be perfect for my bilogy project. could i use

it?

[akjoson]

definitely cool! =P

[ShiroKage009]

not just cool ... They're DEAD cool XD

[asemoknyo]

This is a really great video, it shows actual nematocysts firing without the wanky special effects and sci-fi noises a lot of CG animations of this have.

[Neuve0]

Nature, efficient and precise.

[israelidriver]

wow

[blogmeme]

cool!
