Deadly Blue-ringed Octopus

Despite its size the Blue-ringed Octopus has a fearsome reputation and with good reason. It’s one of the deadliest animals on the face of the planet. Its weapon of choice? Spit. Yep good old spit or saliva. Ok so it might not sound like the weapon of an evil villain but it seems to work. But this is super spit and what makes it so lethal is that it has a deadly neurotoxin in it which is manufactured by bacteria living in its salivary glands. When injected into its prey this super spit paralyses it victims.

when you've gotta go through a minute of a guessing game of what the animal is when it's literally the title of the video you clicked on.

If the other story is in another video, that's fine. Where's the other vid though? Kinda cheap to give a quick build-up and not deliver.

You need some sort of opening, I guess.
Also: how do I not get bitten by those pretty little bastards?
And what about those Zombies!?!
Plague Doctor

Those blue rings give me chills for some reason when i see them
Peter Walker

Jamie has altered sodium channels, so he's immune to BRO, but he's now too slow to avoid Irukandji and spends half his life in the ED.

So was it thousands of years through evolution and trial and error in order to gather all the correct microbes to make the venom?

So how come the venom produced by the bacteria doesn't kill the octopus?
What an extremely likeable guy

You didn't explain where and how the octopus gets its venom since it doesn't make any on its own.

Wasn't there a snail. That feeds of blue bottles that once consumed they get their venom. Komodo dragon gets his venom from bacteria.

For animals such as the blue ringed octopus or poison dart frogs that get toxins from other organisms, how do they keep from being poisoned themselves?
Yevrah Hipstar
Yevrah Hipstar:
Zombie story tease boy, where is it?
I was hoping you explained how this is so venomous when it doesn't produce it itself and how it gets its venom.

There's actually quite a few aquatic species that have TTX produced by symbiotic bacteria. Puffer fish are an example

Longer episodes more in detail and hi Destin. I know it takes a long time to edit videos and shoot stuff and I know you're really busy man James but I could just listen to you talk about this stuff for days I wish more people would subscribe to your channel and actually I'm going home to show my son this channel cuz he'll get a kick out of it

The blue ringed octopus will be the start of the Apocalypse
I though nudibranchs (aeolids) steal venom from sea jellies and anemones .
isint blue ring venom tetrodatoxin..!? same as pufferfish i thought

Seriously? Wait. The hint was unneccesary. We clicked this video because of the title. It's obviously the Blue-Ringed Octopus.

2:20 ; .. is you can actually produce... what. He's not easy to understand - even the auto subtitling doesn't get much of his mumble.
Dart frog doesn't create its own right?
Mark Winter
Mark Winter:
Doesn't the slow Lori produce a venom from the animals it eats.
Probs to the animator.
I thought that the blue dragon sea slug (Glaucus atlanticus) also doesn't produce its own venom.

What’s the other jellyfish that’s really deadly, swear it was Japanese and had a really “japaneesy” name 🤔
James Casey
James Casey:
Just an observation: you're standing with your bare legs exposed in a pool in which you are looking for the blue ringed octopus. I have never understood how care free people are about dangerous animals. Hats off to you for bravery, but damn- I'd go a bit more careful than that.

why don't these videos have more views this is pretty cools stuff and the videos are done well.

Are Ok 'It's own venom' I thought he'd made a basic error, but no the puffer fish get revenge post mortum after it's been eatten.
Puffer fish, fugu also concentrates tetrodotoxin from bacteria present in other animals they prey on but puffer fish don't envenomate, bite.
Farmed fugu is feed a controlled tetrodotoxin free diet so they aren't toxic..
