The geographic cone snail releases insulin into the water to stun its prey, then moves in to engulf and harpoon the fish with deadly neurotoxins

      This cone snail releases insulin-like toxins into the water to induce hypoglycemic shock, causing the fish to become lethargic and sink. Then it engulfs the fish whole with its expandable mouth and rostrum. The snail then extends a long, harpoon-like radula tooth (connected to a venom gland) from its proboscis, stabs the paralyzed fish, and injects a complex cocktail of conotoxins. These conotoxins (including motor cabal and nirvana cabal peptides) rapidly cause neuromuscular paralysis, immobilizing and killing the prey within seconds. This is called the net hunting strategy.

      The geographic cone snail is the most toxic of the roughly 500 known cone snail species, potent enough to kill humans, and there is currently no antivenom for its venom. [Source](https://www.youtube.com/watch?v=LZYBMJesOBQ)

    2. Step 1: Capture thousands of cone snails.

      Step 2: Find way to harvest insulin from them without killing yourself by accident.

      Step 3: Kick Pharmaceutical companies square in their balls by selling insulin at astronomically low prices.

      Step 4: Use cone snails to defend yourself from the Hit-men hired by aforementioned Pharmaceutical companies.

    3. So many crazy types of predators in the water. Friend got spiked by a lionfish while diving and passed out underwater

      Am I bugging or are the snails the most dangerous things in the sea? The percentages of ones that can take you out seems high

      So after its feeds it can’t get back in the shell? Seems eating it is a dangerous activity

      You see the eyes moving, its aware its being eaten

      I sat on the toilet for too long the other day and lost use of my legs below the knee, didn’t matter how much I tried to lift my foot to walk it just wouldn’t, couldn’t feel it either except tingling.

      Not having control of your body is fucking weird, losing control as you watch your death is nightmare furl

      Damn if my insulin was low and a seemingly friendly stranger shared some cookies to help me out I honestly wouldn’t expect them to then stun and eat me whole. I don’t think I’d make it as an aquatic creature, I’ll stay to my mammal caves and wooded areas.

      I got stung by a cone snail a couple years ago. No clue which type. It was agonizing pain for about 5 hours and then my foot doubled in size. A few days later I couldn’t walk on it. Super fun!

      Everything about them is crazy. The way that they completely engulf their prey is horrific too.

      When I said “deadly neurotoxin,” the “deadly” was in massive sarcasm quotes. I could take a bath in this stuff. Put it on cereal, rub it right into my eyes. Honestly, it’s not deadly at all… to *me*. You, on the other hand, are going to find its deadliness… a lot less funny.

      considering how deadly just about everything is in the ocean, Australia is really Atlantis, is it?

      Divers collecting Cone shells have been lethally “bitten” (stung) whilst ascending to their boat with the Cone shell in their hessian collection bag as it leans against their leg. I know of one case where a Cone snail extended the proboscis thought the mesh of the bag and injected the diver in the leg. He lost consciousness and died at the surface. Most of these shells are potentially deadly – with the Geography Cone (Conus geographus) and the Textile Cone (Conus textile) being the two most feared. The Geography Cone has killed over 35 people that we know of, with many other “drowning victims” likely being killed buy the same type of shell. Many reef explorers who know of the danger, often don’t realize they can also reach back and sting the hand even if you’re holding it by the wide base of the shell. When I’ve had to move them or pick them up, I’m always extremely mindful of where the snail is and never take my eyes off it during handling. The venom apparatus behind the radular tooth (which the snail retains in a tiny membrane sack) is forced out at high pressure when the tooth punctures its intended victim. It literally looks like a miniature garden hose under pressure. The radular tooth looks exactly like a whaler’s harpoon… (see pic). It also fires faster than a bullet.

      Whilst all cone snails are venomous, many aren’t likely to kill you… though quite a few species certainly can. Even the scientists who study their venom believe that they all pose a potential threat. The Geographic Cone (Conus geographus), the Textile Cone (Conus textile), the Striated Cone (Conus striatus), and the Tulip Cone (Conus tulipa) are all considered deadly – though many others like the Banded Marble Cone (Conus bandanus) and Hebrew Cone (Conus ebraeus) are potentially capable of killing an unfortunate person. I collect Cone shells for display in my bathroom – but not from the wild. I source them from shell merchants who take all the risk. I think I have about 30 and I replace them with larger specimens from time to time.

    13. That’s as wildly fucked up as star fish having a stomach they completely expel from their body after anchoring down prey beneath them dissolving them with gastric juice from the stomach then sucking the substance into the stomach and then back into their body. 👀

    14. And this is just a regular ass snail.

      This is why I think people always underestimating the immortal snail
