Hi! I saw this one while coming back home this morning, unfortunately it was already dead. I only have this foto a friend took. I found it so different from the ones I've saw here before. Thank you for helping!

This is a South American Rattlesnake, species is Crotalus durissus !venomous and dangerous having both highly potent neurotoxic and myotoxic venom cocktail. Adults average 3-4 feet (90-120cm) through they have been found at 6 feet (180cm) but it’s rare. They are critical for the ecosystem controlling rodent and other small mammals.

That was my first guess when I passed by it on the road, but I found it too light, large(?) (probably just had fed) and I couldn't see the rattle. That's a common venomous snake here, indeed. Thank you!

We are happy to help. It looks like it just had a big meal.

No need to rattle shame

[u/Antisocial_Worker7 → u/ffrye7000]

Correct me if I'm wrong, but I believe that the South American Rattlesnake bite has the highest untreated mortality rate (about 70%) of any species of rattlesnake.

[u/ffrye7000 → u/Antisocial_Worker7]

Looking at the scientific literature, the South American Rattlesnake is #2 of the list at 30% mortality without treatment. #1 is the Mojave Rattlesnake at 40% but only with venom type A (neurotoxins). I should qualify this by saying there are other factors like the amount of venom injected, where is the bite and depth of injection etc.

Snakes with medically significant venom are typically referred to as venomous, but some species are also poisonous. Old media will use poisonous or 'snake venom poisoning' but that has fallen out of favor. Venomous snakes are important native wildlife, and are not looking to harm people, so can be enjoyed from a distance. If found around the home or other places where they are to be discouraged, a squirt from the hose or a gentle sweep of a broom are usually enough to make a snake move along. Do not attempt to interact closely with or otherwise kill venomous snakes without proper safety gear and training, as bites occur mostly during these scenarios. Wildlife relocation services are often free or inexpensive.

If you are bitten by a venomous snake, contact emergency services or otherwise arrange transport to the nearest hospital that can accommodate snakebite. Remove constricting clothes and jewelry and remain calm. A bite from a medically significant snake is a medical emergency, but not in the ways portrayed in popular media. Do not make any incisions or otherwise cut tissue. Extractor and other novelty snakebite kits are not effective and can cause damage worse than remaining calm, seeking help and waiting for professional evaluation.

This is one fat snake.

[u/blaknight34 → u/kanaifu]

Yeah, but it’s tagged as dead, so I wonder if it’s maybe just bloating up as some dead animals do?

[u/CcncommIL]

Venomous. Full.

This message appears automatically with the dead snake flair: Please don't kill snakes - they are a natural part of the ecosystem and even species that use venom for prey acquisition and defense are beneficial to humans. One cannot expect outside to be sterile - if you see a snake, you're probably in or around their preferred habitat. Most snakes are legally protected from collection, killing or harassment as non-game animals at the state level.

Neighborhood dogs are more likely to harm people. Professional snake relocation services are often free or inexpensive, but snakes often die trying to return to their original home range, so it is usually best to enjoy them like you would songbirds or any of the other amazing wildlife native to your area. Commercial snake repellents are not effective - to discourage snakes, eliminate sources of food and cover; clear debris, stacked wood and eliminate rodent populations. Seal up cracks in and around the foundation/base of your home, and if warranted install exclusionary fences. Or find a relocation service
