There are in the neighborhood of 3,000 to 4,000 known species of snakes out there in the world, though of course it's possible more could be identified. Most of those are fairly harmless overall, with around 600 species being venomous.

1. Inland taipan
   King cobra
2. Black mamba
   Tiger rattlesnake

The Inland Taipan is native to Australia, and pound for pound it has the most toxic venom of any snake in the world. A single strike from the Inland Taipan can inject enough venom into the victim to kill 100 grown men, so don't mess with this snake.

There isn't a single species of herbivore snake in the world. All snakes are carnivores and eat meat, so keep an eye on your steak at a barbecue and don't worry about the salad.

1. Titanoboa
   Giant anaconda
2. King's python
   Gigantophis

Fossils have indicated that the largest snake ever was the Titanoboa. It lived about 60 million years ago and grew to be over 40 feet long while reaching a weight of over one ton.

1. Two inches
   Four inches
2. Six inches
   Nine inches

The scientific name for this little guy is "Leptotyphlops carlae," and it only grows to four inches long. They're also about as thin as a spaghetti noodle and weren't discovered until 2008. It's no wonder no one noticed them before if they're that small.

1. All of them
   70%
2. 50%
   30%

Surprisingly, not all snakes lay eggs. About 70% of snake species lay eggs, but the other 30% keep the eggs inside so they can live birth the young. This is due to the climate where the snakes live being too cold for the eggs.

1. About 10 miles per hour
   About 12 miles per hour
2. About 15 miles per hour
   About 20 miles per hour

The black mamba can move at speeds up to 12 miles per hour and is considered the most dangerous snake in the world, even though its venom is not the most toxic. The speed combined with aggression and a potent venom is what makes it so dangerous.

1. Keratin
   Brille
2. Dew Flaps
   Molt

The brille, sometimes called simply ocular scales, are clear scales that cover the snake's eye. Like the rest of a snake's scales, they will come off as the snake sheds its skin and are replaced with new scales.

1. Jacobson's organ
   Crepuscular organ
2. Reticulated organ
   Nasal patch

The Jacobson's organ is also called the vomeronasal organ. When a snake flicks out its tongue, it will retract it and press it against the Jacobson's organ. Scent particles in the air are caught by the tongue and detected by the organ, which lets the snake know it's smelling something like prey in the air.

The research on this one was not 100% certain, but the estimation was that 20,000 people a year die from snake bites. The researchers also added that, due to unreported incidents and other factors, that number could be as high as a staggering 94,000 deaths per year

1. You can't
   Genetic testing
2. Legless lizards have eyelids.
   Snakes are always longer.

Legless lizards and snakes are two different animals entirely; they just look the same at first glance. One of the easiest features that helps distinguish them is the fact lizards have eyelids and snakes don't.

1. Snakes have one large right lung.
   Snakes have three lungs.
2. Snakes have no lungs.
   A snake's lungs and heart are the same organ.

Snakes do have two lungs, but the left lung is undersized and sometimes just used for buoyancy. The right lung is the one that does most of the work in a snake.

1. It slows down.
   The rhythm of the pulse will change.
2. It actually grows larger.
   Nothing

Research has shown that after a snake eats a large meal, its internal structure actually changes to accommodate that meal. A python's heart can grow 40% larger. It's believed this happens to allow the snake to pump blood faster through the body after it has eaten.

   Like hibernating, but during the hottest months

Aestivation is essentially hibernation, but instead of occurring during the coldest winter months, it occurs during the peak of hot, dry seasons. The point is to lower the metabolic rate and preserve moisture—basically to wait out the harshest temperatures until things are more tolerable.

1. Six months
   One year
2. Three years
   Never

Like most animals, a snake's growth does even out a bit in time, but it never truly stops growing. For as long as the snake lives, it will continue to grow in size.

1. One month
   Three months
2. Five months
   Over six months

Studies have shown a number of species of snakes can survive for over six months without food. Bizarrely, the snakes will actually continue to grow during that time. It's likely snakes could survive much longer, but it's definitely not safe to make a snake do that.

1. They have valved nostrils and can breathe through their skin.
   They breathe water like fish.
2. They're just regular snakes that hold their breath for a while.
   They never go below the surface.

True sea snakes live their whole lives in water and in fact can't survive on land because they lack the same scales as their terrestrial cousins that help them navigate dry land. When submerged, their valved nostrils close up to prevent water from getting in, and they are also able to breathe through their skin, which allows for more air absorption and longer dives below the surface.

1. Three feet
   Six feet
2. 10 feet
   15 feet

The danger zone for a spitting cobra is within about six feet. After that, you still want to keep your distance, but it's much less likely to hit you. Not only can these snakes spit venom, but they do so with amazing accuracy, aiming specifically for the eyes of their prey. The toxins in the venom could blind a human.

1. Gaboon viper
   Tiger rattlesnake
2. Golden lancehead pit viper
   Green anaconda

Snake Island, also known as "Ilha da Queimada Grande," is home to a massive population of golden lancehead pit vipers, which are highly aggressive and deadly. It's believed there is at least one snake for every square meter of space on the island.

1. Suck the poison out
   Tie off the wound with a tourniquet
2. Apply a pressure bandage and call an ambulance
   Clean the wound thoroughly

Putting a clean, dry bandage on the wound and calling for help is the go-to response for a snake bite. Never, ever try to suck out the poison or clean it, as this can make it spread faster through your bloodstream. Also, don't try to catch the snake; you don't want to get bit again.

1. Ball python
   Rainbow boa
2. Corn snake
   Reticulated python

Ball pythons are extremely common pets among snake-lovers because they tend to be very even-tempered. You can find ball pythons at just about any pet store across North America.

1. Ball python
   Garter snake
2. Brown snake
   Corn snake

The garter snake, sometimes called a gardener snake, can be found all across the country and throughout Canada as well. Though harmless to humans, they actually do possess a very mild venom that helps them subdue prey.

1. It's like any rattle; there's stuff inside.
   It's not actually the tail but the snake itself.
2. It's the segments of the rattle clicking together.
   The rattle has to rub against something.

A baby's rattle may have little beads inside but a snake rattle does not. Instead, every time the rattlesnake sheds, a segment is added onto the tail. These segments click together when the snake shakes and vibrates its tail, creating the rattle effect.

Despite the famous story about St. Patrick driving the snakes out of Ireland, there are no actual snakes in Ireland and no evidence there ever was. Maybe that's how St. Patrick convinced everyone he'd done the job.

1. None
   All
2. Just the constrictors
   Just the venomous ones

Snakes mouths just aren't designed for chewing. No matter how a snake captures its prey, whether by constriction or by using venom, they have to swallow it whole.

1. Over 2,000 pounds
   Over 1,000 pounds
2. Over 500 pounds
   Over 300 pounds

Even though some snakes do reach longer length, the green anaconda is the most massive species currently alive. The snakes can reach around 17 to 20 feet in length, though some have grown much bigger, and break the scales at over 500 pounds.

1. Pit viper
   King cobra
2. Gaboon viper
   Inland taipan

The Gaboon viper has the longest fangs of any snake species. They have been recorded at lengths of up to two inches. The fangs are actually hinged in the snake's mouth so that they can fold up when not in use.

1. Safe bite
   Dry bite
2. Warning bite
   Weak bite

A snake like a viper can choose when it will inject venom, and as such it can bite something like a person's foot without actually envenomating the wound, which is referred to as a dry bite. Many human bites are actually dry bites.

1. 50 feet
   100 feet
2. 200 feet
   Over 300 feet

Flying snakes have been recorded traveling distances of 100 meters or over 300 feet on a single glide. They are able to suck in their abdomens and flatten then bodies until they look kind of like a long, flat wing and are fairly adept at aiming themselves at a target, which they then glide toward.

1. Lamellar bone
   Keratin
2. Cosmine
   Elastin

Keratin is what snake scales are made of, and also the upper layer of fish scales as well. You probably recognize keratin as the same substance that human fingernails and hair is made from. It's versatile stuff!

1. Les Stroud
   Bear Grylls
2. Paul Rosolie
   Paul Rudd

"Eaten Alive" was a special that Discovery aired in 2014 which promised to show Paul Rosolie being eaten by a green anaconda. Rosolie was wearing a special body suit and had a breathing apparatus that would supposedly keep him alive. Instead, he panicked as the snake began trying to eat him, and it was all called off.

1. They only give birth to quintuplets.
   It can only reproduce in the snow.
2. They reproduce asexually.
   They make a whistling sound.

Flowerpot snakes are bizarre little creatures that reproduce asexually. All known snakes in the species are female, and their young are all genetically identical to the mother.

1. Olive sea snake
   Kimberly death adder
2. Rat snake
   Indian cobra

The olive sea snake may not be the only snake with photoreceptors, but it is certainly one of the few ever identified. It's believed these cells help the snake hide from view by ensuring it can tell of all of its body, even the top of its tail, is in the shadows.

1. Hydrophobia
   Triskaidekaphobia
2. Ophidiophobia
   Globophobia

Ophidiophobia, the fear of snakes, is sometimes called herpetophobia. It gets its weird name from the Greek word for snake, which is "ophis."

1. A few hours
   24 hours
2. Several days
   Weeks

Anacondas can take down some very large prey like deer or crocodiles, but the trade-off is it takes a very long time to finish that meal. Large prey can literally take weeks to fully digest.
