Snakes can kill in numerous ways, including poisoning, crushing and eating their victims.
Here are some of the craziest snake attacks on record, including animals and humans -- some of whom lived to tell the tale, and some of whom did not.

Python bites Thai man's penis
A Thai man recovered fully after a 10-foot python slithered through the plumbing of his home and latched its jaws onto his penis as he was using a squat toilet in May 2016.
The victim, Attaporn Boonmakchuay, said that he struggled to remove the snake for 30 minutes before he managed to free himself with help from his wife and a neighbor.
The snake was released back into the wild
Emergency workers dismantled the squat toilet to remove the python after the man freed himself. The snake was released back into the wild.
Python swallows house cat whole
A python in Brisbane, Australia swallowed a house cat whole in March 2016, according to Snakeout Brisbane, a professional snake catching service.
The company posted a video of the ordeal to their website to warn pet owners.
Diamond pythons are often found in Australia. They can grow to about 13 feet in length, and have also been known to swallow small dogs.
Burmese Python crushes zookeeper
In August 2008, a 10-foot Burmese Python bit a student zookeeper at the Caracas zoo in Venezuela and then crushed him to death.
Fellow employees found the snake trying to swallow the victim's head, according to the BBC. The victim had apparently let the snake out of its enclosure while working a night shift.
Invasive in South Florida
In the spring of 2017, South Florida hired 25 top snake hunters to capture and kill Burmese pythons, an invasive species in the Florida Everglades.
Hunters trapped roughly 100 snakes in the first six weeks. Leo Sanchez and Nicholas Banos, pictured here, nabbed a 15-footer. It weighed 144 pounds.
Copperhead bites woman three times
Rachel Myrick, a Virginia woman, was bitten three times by an 8-inch-long copperhead snake while at a LongHorn Steakhouse in September 2017.
Myrick said the pain was excruciating. She was hospitalized for swelling that spread past her knee and all the way to her hip and thigh.
Burmese pythons can reach 23 feet in length and can weigh up to 200 pounds.
They kill by first biting victims with very sharp teeth and then wrapping their bodies around their prey until it suffocates.
Black mamba snakes poison woman
Cheposait Adomo was walking home from a party in Kenya in 2016 when she was bitten repeatedly by a black mamba that wrapped itself around her ankles, she told The Huffington Post.
Before she knew it, two other black mambas had also wrapped themselves around her legs, and they had to be hacked off by men with machetes.
Black mambas are often considered the world's deadliest snake because they are lethally venomous and very fast.
The bites left Cheposait Adomo feeling dizzy from the snakes' venom, but she survived the attack. The hospital she was transported to fortunately had anti-venom on hand, which is not always the case in Kenya.
Python coils around Zambian man in truck
A 25-year-old excavator driver accidentally scooped up a python, which coiled itself around him in the car of his truck in Zambia in May 2013.
He fought off the python by biting it but took more than a month to recover from his injuries, according to the AFP news agency.
Anaconda coils around Brazilian boy
A 16-foot-long anaconda wrapped itself around a 8-year-old boy in Brazil in 2007, according to the Associated Press.
His grandfather came to his rescue, but it took the 66-year-old man a half hour to uncoil the snake from the boy's body.
The boy recovered
The boy survived but had been bitten by the snake and needed 21 stitches.
Anacondas don't kill their prey by transmitting venom through a bite. Instead, they suffocate victims by wrapping their bodies around an animal until it stops breathing.
One anaconda can weigh as much as 550 pounds.
Big, but not necessarily bold
Despite the obvious size and strength of anacondas, not all humans fear them. This anaconda was reportedly the adopted pet of a group of soldiers in Tabatinga, Brazil.
Girl bitten by copperhead in pool
A 9-year-old girl was bitten by a copperhead snake while swimming in her family's pool in Alabama, according to CBS affiliate WBRC.
The girl, Chappell Williams, was treated at the hospital and recovered quickly.
Word to the wise: Do not kiss rattlesnakes
Florida man Ron Reinold was bitten by a rattlesnake in May 2017 after he leaned in to kiss the snake.
He was airlifted to a hospital in critical condition, but survived.
Or decapitate rattlesnakes
When a Texas man encountered a four-foot rattlesnake in June 2018, he decapitated it with a shovel. Then the severed head bit him.
Snakes can still attack even an hour after they've been beheaded, and a decapitated snake head will likely release all of its venom at once during the bite. The man was hospitalized but survived.
Rattlesnake bites golden retriever
Todd, an Arizona dog, was on a hike with his owner, Paula Godwin, in June 2018 when Godwin nearly stepped on a rattlesnake. But Todd leaped between his owner and the snake and was bitten himself.
Todd was treated for the bite on his snout at an animal hospital and survived.
Rattlesnake hiding in toys bites boy
A 1-year-old boy was hospitalized in June 2018 after he was bitten by a rattlesnake hiding in some of his toys. The boy was playing outside of his Abilene, Texas, home when he was bitten. He survived the attack after treatment.
Rattlesnakes, which can range in length from one to eight feet, can strike with a venomous bite at speeds of five-tenths of a second.
Their venom is extremely potent, and scientists have found that rattlesnakes are developing even more toxic venom due to evolutionary progress.
Python eats porcupine
A 12-foot-long African rock python in South Africa died after swallowing a porcupine in June 2015, according to officials at Lake Eland Game Reserve.
Quills killed snake
Rangers weren't sure at first what the snake had eaten to become so swollen, but after it died, they cut it open and found the porcupine's quills had punctured the snake's digestive tract.
Brothers strangled by python
In 2013, two young Canadian brothers were strangled by an African rock python in their sleep.
The brothers had been visiting the apartment of a friend whose father owned an exotic pet store on the floor below. The snake, however, was likely being kept in the apartment where the boys were sleeping.
African rock pythons
African rock pythons are considered an invasive species in places such as Florida, where teams of snake hunters have been known to check levees and canals for signs of the reptile.
Python versus alligator
A 13-foot Burmese python in Florida tried to eat a 6-foot-long alligator in September 2006.
The gator was found protruding from the snake's midsection. The snake was also found headless, which suggests another alligator might have retaliated by biting off the python's head, according to National Geographic.
Python swallows Indonesian man
The body of a 25-year-old Indonesian man who went missing in March 2017 was found inside the belly of a giant python.
Villagers said the 23-foot reticulated python apparently attacked the man from behind and swallowed him whole. They suspected the snake had eaten the man because the creature was bloated and moving awkwardly.
Reticulated pythons are among the world's largest reptiles, often growing to lengths of 20 feet or more. They are commonly found in the Philippines and Indonesia.
Not even as big as they get
If 20 feet of reticulated python frightens you, consider: They can get even bigger. This one, found in forest in Sumatra in 2003, stretched to 49 feet and tipped the scales at 983 pounds. No word on what it preferred to eat.
Python strangles 2-year-old girl
In 2011, Jaren Hare and Jason Damell were found guilty of third degree murder, manslaughter and child neglect after their pet python strangled a 2-year-old girl in their care.
Trial testimony revealed the python had not been fed for a month and had wrapped itself around the toddler in an attempt to eat her.
Albino Burmese python
The snake, named Gypsy, was an albino Burmese python similar to this one, according to the Orlando Sentinel.
The 8-foot-6-inch snake was known to escape from its glass enclosure, which only had a safety-pinned quilt as a cover.
Python squeezes man to death in Malaysia
In 1995, a 23-foot python squeezed a rubber plantation worker in Malaysia to death and tried to swallow him, according to The Associated Press.
The python, which was fatally shot by police, had already swallowed the victim's head and crushed some of his bones when discovered.
