Venom Potency and Effects
Russell’s viper packs quite a punch in its venomous bite, and understanding how this venom works its black magic on the human body is vital for anyone who might cross paths with this snake in places like Sri Lanka.
Venom Production
Russell’s vipers aren’t stingy when it comes to dishing out venom. They’ve got a nifty system called solenoglyphous dentition to deliver the goods. Adult snakes can pump out venom amounts from 130-250 mg, with a few overachievers hitting the 268 mg mark.
| Snake Type | Venom Yield (mg) |
|---|---|
| Adults | 130-250 |
| Max Reported | 268 |
| Juveniles | 8-79 |
| Lethal Dose for Folks | 40-70 |
Table from Animalia
With a lethal dose for humans sitting between 40-70 mg, even a one-on-one with an adult viper can be a ticket to the afterlife (Wikipedia).
Symptoms of Envenomation
Run-ins with Russell’s viper venom are no joke. Symptoms hit fast and hard:
- Ouch and Puff: Sharp pain and swelling where the snake strikes.
- Bloody Mess: The venom messes with your blood’s ability to clot, causing bleeding you can’t see (russells viper hemorrhagic effects).
- Brain Scrambler: Dizziness, passing out, and the big freeze (paralysis).
- Kidney Trouble: Trouble can get bad enough to shut your kidneys down.
- Blood Mayhem: Normal blood clotting goes out the window.
These problems need a fast doctor visit. Antivenom is the go-to fix, and smart folks at places like the Costa Rican Clodomiro Picado Institute are cooking up new ones that look promising (Wikipedia).
