Why Australian snakes are so venomous

Why Australian snakes are so venomous

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 venomous. What we discovered is that it depends on a number of factors including:

  • How much food is available;
  • The volume of venom the snakes produce;
  • Minimising injury to the snake; and
  • The potency of the venom.

Scaring scorpions makes them more venomous

Scaring scorpions makes them more venomous

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 up in this case..) Scorpions have two components to their venom. One for using in defence against furry animals with sharp teeth such as small marsupials and mice who like to eat scorpions and the other to capture prey such as crickets and spiders.

What researches found was that when the scorpion was regularly exposed to predators i.e the highly frightening frankenmouse, the amount of venom for defence increased and the venom for capturing prey decreased.
Which makes perfect sense, you need to try and give anything that is going to eat you as much whoop-ass as possible which comes in the form of a deadly tail fashioned with a venomous sting.

What is even more amazing is that they can do this within 4 weeks! If a venomous snake tried to pull that off, it would take them generations, which makes it super cool for a scorpion to be a super scary cat. The key message here… embrace your vulnerable side it could give you super powers. Don’t take our work for it, check out the video.

How venom kills – Venom 101

How venom kills – Venom 101

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 that Assoc. Professor Jamie Seymour knows a thing or ten about, after all that’s his shtick. So given that he’s a fun-loving sharing kind of guy he given us a bit of a lesson, kind a like a venom 101 of his world (which is venomology and toxinology which are tricky words to say let alone spell) showing us how they work on their victims which sometimes include the human-kind, and the results are….. all sorts of awesome! He also sets us straight us straight on the difference venom and poison, which we will now be able to use with so much confidence, the world will think he has been cloned!

Deadly Jelly Wrestling

Think you could handle a career jelly wrestling? You’ll get sweaty with the long hot sticky nights but here’s a tip – It doesn’t include buxom babes in skimpy bikini’s in a jelly filled blow up pool. For this type of wrestling, your pool is the warm tropical waters of North Queensland and your opponents are pulsating gelatinous jellies with deadly tentacles.

Attack of the killer cone snail

Attack of the killer cone snail

 

It’s not the fastest animal going around, but what the cone shell has is patience, persistence and…… venomous harpoons that makes any animal wish it hadn’t crossed paths with it.

 

In this little video you can see the stromb shell trying to escape. It usually moves around on a big sticky foot, but dangerous situations like this call for more urgent action, so it uses its foot to jump away.

 

It’s a case of the tortoise and the hare. The stromb is quick to get out of the way, the cone shell; slow, patient and relentless. When the stromb is exhausted the cone pounces (actually it just slimes its way) on the stromb.

 

In this video you can see the oral siphon (the pink tip and black and white striped organ) smelling out its prey. When the prey is located and locked in on the cone shells proboscis (the bright orange thingy searching) comes out of the mouth, searches for a weak spot on its prey (in this case the soft flesh of the stromb) and delivers the final blow…. A venom loaded harpoon called a radula which paralyses the stromb and it’s eaten whole.

 

You can actually see the venom in the water, it’s the cloudy substance that comes out of the snail and to the left of the camera.

Jellyfishing

Meet the world’s deadliest fisher, the Irukandji Jellyfish. This tiny jellyfish has extendable arms that are loaded with venom filled harpoons. To attract prey the Irukandji extends then quickly retracts sections of it’s long arms, like it is ‘jigging‘ for fish. When contact is made with the arms, a barrage of venom filled harpoons (nematocysts) are unleashed on the unsuspecting victim.

They’re like the gangster of the spider world, big, brutish, hairy and downright scary. The kind of spider you wouldn’t want to bump into in a dark alley. Mess with the Sydney Funnel Web Spider and you could find yourself going home in body bag.

Admittedly this spider has a bad reputation and we’re really not helping here. So, appearances and gangster reputation aside, they pretty impressive creatures. Their signature is a set of thick fangs, which would make Dracula blush.

Male venom more toxic

Male venom more toxic

Male venom more toxic

It seems males and females are not created equal, especially when it comes to venom. Enter the Sydney Funnel Web spider, a hairy and scary looking spider that can be found in the moist cool forest areas of ….you guessed it, Sydney Australia.

Life starts off as an equal playing field (apart from the obvious differences in girl and boy bits) with the venom profiles being the same. They spend the first few years of their lives hanging around close to their burrows, which are usually found under rocks, rotting logs and in leaf litter.

Poisonous Cure

It turns out that a hairy and scary looking spider with fangs to rival Dracula has venom that can kill humans but also has the potential to cure cancer. When researchers exposed components of the venom to breast cancer cells, they died.
