Jet powered dumplings you need to meet, not eat
If dumbo and a hovercraft made out, this is what you’d get. We admit we have a pretty warped sense of humour. But when you sit back and look at it, the Dumpling Squid does kinda look like a potential 'love-child' of the two don't you think?
Now before you get all excited, unlike some of it’s other relatives this is not the type of dumpling squid you would see served up at yum cha. Bummer we know… It’s only 7cm long, so even if you found them at an all you could eat buffet, they still wouldn’t fill you up.
They’re a type of bobtail squid that you find at night along the cooler southern shores of Australia, typically in sandy habitats and seagrass areas. The bonus is, their cuteness can also be found in their cousins that live all around the world.
They move around using two forms of locomotion. The hilarious body fins on the side of their heads, which they flap like wings and jet propulsion. They achieve this by contracting their mantle or body which squeezes water out past their head through a siphon.
As you can imagine these squid are tasty little delicacies in the sea for a range of animals, so they have a number of ways to avoid being eaten.
They can produce ink which acts as a decoy and allows them to escape. They can play hide’n’seek by hiding under a sandy cloak, using mucus glands to glue the sand on (which it can also shed as a decoy) and if all else fails they can bury themselves in the sand.
When they’re not being scaredy-cats and hiding you’ll find then hunting at night where they feed on shrimps. A set of the retractable tentacles makes sure that no shrimp gets away.
When it comes to making more dumpling squid…. A male will hold onto their female with four of his arms where he gives her his love (in the form of a sperm packet) and they can spend about 3 hours in a squid embrace. They're so tired after this they go into what scientists describe as a ‘squid sex coma’ where they can’t swim and need to rest for up to 30mins, usually hiding in the sand to avoid predators.

Why Australian snakes are so venomous
Переглядів 1,9 млн7 років тому
Australia is known as the place with all the deadly animals. Whether they have fur, fins, shells or scales, Australia has them. Snakes are no exception. In fact Australia is known to have loads of venomous snakes. Some of the most venomous on the planet. Think the Inland Taipan, Brown, Mulga, Death Adder and Tiger Snakes. So the TNOS team set out to explore just why our snakes are so darn venom...
Creepy Giant Spider Crab Aggregation

There is getting crabby... but this is just all out ridiculous! We have never seen soooooo many crabs. We know some people are going to be freaked out, but us? Hey throw is in there and let them crawl over us (did I mention we were a weird bunch??? ) Every year as the waters cool on the southern shores, hundreds of thousands of Giant Spider crabs find their way up on the sandy shallows Rye and ...
Extreme fishing - Fish that fishes with a rod and lure fused to its face

There is extreme fishing and then is going to such extremes that you have a rod and a worm-like lure fused to your face. Quite frankly it's the type of commitment we admire. Meet the Tasselled Anglerfish the ultimate fisher. Nothing escapes this angler. It’s the master of disguise with camouflage so brilliant it can sit out in the open and not be seen. Silent and still it either waits for their...
Scaring scorpions makes them more venomous
Переглядів 1,6 млн8 років тому
Although they look all A-team tough on the exterior with armour-plating and a don’t mess with me stinging tail, scorpions can actually be a bunch of scaredy cats. But don’t take this as a weakness because the scarder (yes that is a word, Google said so…) they are, the more potent their venom becomes. No-one has been able to show this in any other venomous animal. Here’s how it all goes down (or...
Living up a bum - The Sea Cucumber and Pearl Fish

They say 'Home is where the heart is', well for some 'Home is where the bum is'.. Wait! What? Backup! Yep you heard right 'Home is where the bum is', if you're a pearl fish and that bum is a sea cucumber. Sea cucumbers are sausage shape animals that are found on the bottom of the ocean where they vacuum up the sand and filter out all the good bits. It seems as though pearl fish have taken a bit...
How venoms kill - Venom 101
Переглядів 2,4 млн8 років тому
Venom... the word sends chills up your spine at the mere mention of it. And with good reason. Its aim is to incapacitate its victims and boy does it work a treat. What's really interesting is that not all venoms are equal and not all work the same way. They're as diverse as the animals that deliver it. From clotting blood, causing paralysis and destroying living cells. It's a fascinating world ...

How killer cone snails kill

This cocktail essentially kill their victims half a dozen different ways. Once the prey has been immobilised it is ...
Irukandji Jellyfish - World's deadliest fishing

The Irukandji jellyfish, fish for fish using deadly extendable arms that are covered in venomous stinging cells. As it swims along, this tiny jelly extends its tentacles and twitches them much like a fisher or fly-fisher would to attract prey in the water. The balls of venomous stinging cells (nematocysts) act like a lure and attract fish. When contact is made with the tentacles the venomous ha...

The Venomous Stonefish - World’s Deadliest Garden

Meet the stonefish, the world's most venomous fish. It has the bragging rights as one of the most deadly fish in the sea, with venomous spines that are lethal. The upside for any fish is that it doesn’t use these spines for hunting. The downside, it’s a master of camouflage. It secrets a liquid-like fertiliser called crynotoxin (meaning toxic skin), which it covers the all over it's body to att...
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 manufac...
I really thought they move into the other direction
RIP lego man.
I am lucky to be alive! My parents decided we might move to Africa when I was a kid of 7yrs. We settled for a while in Mombasa living on an isolated property with ocean frontage, it was a snorkellers paradise and heaven for a youngster, I spent many days out on the reef snorkelling on my own, I don't know why my parents didn't put me in boarding school butI didn't argue. I can remember picking up Tapestry and Geographic Cones off the reef to add to my collection, I would hold the shell in one hand and watch this little brown ""plastic"" serrated spear attached to a tube like part of the head of the cone, it would come waving out seeming like it was searching. I would grab that ""spear"" between my thumb and fingers of my right hand and try to pull the snail out of its shell. If it was a good specimen I would put it in my bag that I kept tucked in the leg of my swimmers to. It wasn't until we came to Australia eight years later that I was told that they were poisonous, in fact I think they were only discovered to be poisonous the year before we got here in 1967
PLUMS!
Wow
Damn dude the snake is bleeding that's shitty
Only venomous if they hit you with that prod
Venomous snakes are around the world not only in AUSTRALIA
These toxins are amazing
ok... mother nature, what else isn't deadly?🥲
Looked liked the Chocolate Malt machine!!
2 minutes,,heck even if peeing on it worked,,i'd be dead holding my ,,,
Thanks for explaining this and putting it across well🇬🇧
Are there any nice, non-venomous snakes in Australia?
Of course, Australia
They do not hunt eachother down?
That is the scariest shit ive seen. Leave it to Australia to still scare the shit out of a 55 year old veteran. Sometimes you wonder what isn't deadly in Australia thank goodness its a island of death.
Amazing video, thanks !
"more potent than morphine"- That just sounds stupid
Pearlfish is to the sea cucumber what Israel is to Uncle Sam
I like irukandji jellyfish.
How did they even catch it?
I love Dr Jamie Seymour. He's responsible for my obsession with marine life
🔥
Its like Joe Biden and Kamala Harris!
Awesome
At first I thought the pearl fish and the sea cucumber weren't alive anymore but I think I saw the sea cucumber move by itself when the endoscope was in it.
I don’t think Danno realizes how small they are they grow to like 5 to 8 inches
I’ve been bitten by a black widow spider and my first time I had pains in the bite area for days accompanied by a fever. I got bit again while moving stuff around my garage but with lesser symptoms and third time just pain in the bite area. Human body is amazing at adjusting. But don’t just let yourself but just to get adjusted lol I also got stung by an Arizona bark scorpion a couple of times.
I remember that background music from the bike race app lol brings back memories
How does the cone snail decide what type of venom to produce that will work first time every time? Does it have some kind of victim screening sensory organ to help it decide which components to combine together to be injected? That would be an even bigger discovery.
Unbelievable venomous the australian Taipan, brown snake and tiger snake. However, I believe a King Cobra would eat them all as breakfast 😉
Size and resistance to snake venom matters as to who eats who in the snake eating world.
Blue Maylayan coral snakes eat younger King Cobras in Asia.
Thanks dear lord for your kind mercy for not creating me as "sea cucumber"
Cones rule!
The answer to the question is at 5:20 for those who want to skip the rest
"Why Australian snakes are so venomous?" Prey density? Where is the graph that shows you have more mice than other parts of the world?
The amazing thing to me is how they are NOT killed by their own venom!
The inland has more venom in the vile how do u possibly see more venom in the 1st as compared to the 2nd u need ur glasses adjusted 😅
which animal hunts them?
Where's my million dollars?
they look like tanks marching to battle along the bottom of the tank
SpongeBob you need to get rid of Gary before he gets you 😂
Interesting, but it didn't really explain why Australian Snakes (or African Snakes, for that matter,) are so venomous; maybe the reason goes all the way back, to The breakup of Gondwanaland, and the migration of The Indian Subcontinent, to South Asia. Laurentian, and Eurasian Snakes, seem to be less venomous, or use a different kind of venom (more hemotoxic, instead of neurotoxic). Maybe, it's tied to the preys' ability to fight back, and wound the snake. I saw a program, about the Miami Serpentarium, and it's Curator, years ago; who embarked on a program to make himself a "universal donor" of blood, containing venom antivenin, for several species, and He was called upon, many times, to provide lifesaving transfusions, for many people; perhaps, this program should be revived, and expanded.
Fortunately, snakes has no brain like humans cause if they do, humanity would cease to exist. Specially they get hunt and killed even though they ran fast away from human, human will follow them and smash their heads for more no reason.
Epic stuff sir ❤
Are we gonna ignore the fact that 4 cone snails are fighting
Sigh…*unzips*
SpongeBob was a war movie this would be the APC’S/tanks😂
