Snake island off coast of Brazil; not gonna go there ever...

"Because B. insularis is only found in an area uninhabited by humans, there has never been an official report of a human being bitten by one, but other lanceheads are responsible for more human mortality than any other group of snakes in either North or South America.[2] Ludwig Trutnau reports four human envenomations, three of which were fatal. The mortality rate for lancehead envenomations is 0.5–3% if the patient receives treatment and 7% if the patient does not receive treatment.[2] The effects of envenomations by lanceheads include swelling, local pain, nausea and vomiting, blood blisters, bruising, blood in the vomit and urine, intestinal bleeding, kidney failure, hemorrhage in the brain and severe necrosis of muscular tissue.[6] Chemical analysis of the venom of B. insularis suggests that it is five times as potent as that of B. jararaca and is the fastest acting venom in the genus Bothrops.[4] They have hemotoxic venom that eats away at flesh and tissue to digest the prey item before they swallow it. Bothrops insularis also have some neurotoxic venom that kills the prey item."

That's not a bad mortality rate. Rattlesnakes are worse, no?

I would think it may be higher and that would only be given there proximity to humans; The one's I've seen do not normally go after people; they usually bite when cornered or surprised.

I saw a copperhead that a forklift ran over at work and it's body was as big around as my forearm and it had a beautiful leaf pattern that would have made it hard to see.

I generally leave snakes and such alone...why tempt fate?
