About This Quiz

Swift, sneaky, scary... snakes scare us and fascinate us in equal measure, especially the ones with a deadly bite! But knowledge is power, so test your snake savvy with our quiz!

Why is it incorrect to call a venomous snake a "poisonous snake"?

Something that is poisonous must be ingested to do its damage. Venom is a toxin that is injected into the prey's flesh, often via fangs. A venomous snake would only be poisonous if you ate it and the venom stored in its glands harmed you.

Is "venomous" a term that only applies to snakes?

Although when you say "venom" many people will think of snake venom, other animals have toxic saliva as well. Even platypuses have a toxin injected with spikes on their feet -- and they looked so cute!

Which snake was long erroneously believed to be the most venomous?

This was due to improper testing methodology, and was perpetuated by a book called "Snakes in Question: The Smithsonian Answer Book." This sea snake is also often mistakenly called the "hook-nosed sea snake." Boy, it really needs a good publicist!

Which snake is actually the most venomous?

Is anyone surprised that this most deadly of snakes is native to Australia? We didn't think so!

Many of the most venomous snakes, including the inland taipan, cause very few human deaths. Why is this?

The inland taipan, which has the most toxic, potentially deadly bite, actually avoids people. Some articles even describe it as docile. (Even so, we're not adopting one as a pet!)

What is the name for a person who studies snakes, venomous or not?

More broadly, herpetology is the study of reptiles and amphibians. It comes from a Greek word, meaning "to creep."

The mongoose is immune to cobra venom. Cobra and mongoose fights were popular in India, but have declined because of pressure from animal-rights activists.

What subfamily is the rattlesnake part of?

Species names include Crotalus horridus and Crotalus atrox. "Horridus" probably needs no translation; "atrox" is the Latin root of English's "atrocious."

Why are young rattlesnakes considered more dangerous than adult ones?

Hikers and campers know to listen for the "castanet" noise of a rattler. But adolescent snakes don't have fully-developed rattles yet, and they can't make this sound.

What color is a black mamba?

Black mambas aren't really black -- at least, not on the outside. The interior of their mouths are black, and since this is what the victim sees just before they bite, well, it made a big enough impression to give the snake its name.

How is the viper subfamily different from other venomous snakes?

Vipers do create eggs, like other snakes, but the eggs remain inside the body until the young are born live. This seems like one of those times when evolution wasn't able to make up its mind, splitting the difference between two modes of reproduction.

Some snake venom, like that of the coral snake, is neurotoxic. What does this mean?

These venoms can disrupt motor function, learning and memory. They don't go straight to the brain, but if they get across the blood-brain barrier -- the brain's "firewall" -- that's when serious damage can occur.

Finish the phrase: "Red touching black, safe from attack; red touching yellow, kills a _______."

Okay, this one was easy. But it's meant to be -- it's a mnemonic to help hikers distinguish between the harmless kingsnake, whose red and black bands touch, and the killer coral snake, whose red and yellow bands are adjacent.

Venomous snakes too small to kill humans can still cause necrosis. What does this mean?

Necrosis is when tissue dies. Often snakebite survivors have to have the dead tissue surgically removed, which is called debridement.

Most venomous snakes are oviparous. What does this mean?

It's not just venomous snakes which lay eggs, but non-venomous ones. Also most reptiles... and, of course, birds.
