We have covered many animal topics on Listverse before, but this is our first list of badass animals. These are not necessarily dangerous or scary creatures – but they do all have one thing in common: they are very unique. The criteria for this list: the animal must be alive (ie, no dinosaurs), and it must be awesome. Without further ado, the ten most badass living creatures.
The komodo dragon is the largest living species of lizard, growing to an average length of 2 to 3 metres (6.6 to 9.8 ft) and weighing around 70 kilograms (150 lb). Their unusual size is attributed to island gigantism, since there are no other carnivorous animals to fill the niche on the islands where they live. Although attacks are very rare, Komodo dragons have been known to attack humans; five people have been killed since 1974. One of the most recent attacks in 2007 was blamed on environmentalists who have protested to have goat sacrifices stopped. Komodo dragons are quite smart and can recognize different humans. They also play with toys like humans and (for the most part) behave tamely when in captivity. The most amazing (and badass) characteristic of the komodo dragon is that the female can lay eggs that hatch without being fertilized by a male (this is called parthenogenesis).
The Giant African snail is so badass and huge that in order to eradicate it, people employ the use of flame throwers. In recent times, the land snails have been kept as pets; however, they are illegal to possess in some countries including the United States. The snails are easy to keep and, when bred in captivity, are unlikely to carry parasites. They are hermaphrodites who produce both eggs and sperm but while they are able to reproduce asexually, they do usually mate with other giant snails. Oh – and these snails love to drink beer because the yeast stimulates their growth.
Flying snakes are mildly venomous, though they are considered harmless because their toxicity is not dangerous to humans. But, while it may be harmless, this snake has an amazing ability which makes it both badass and horrifying. It is able to throw itself from one place to another while slithering in the sky. Upon reaching the end of a tree’s branch, the snake continues moving until its tail dangles from the branch’s end. It then makes a J shape bend, leans forward to select the level of inclination it wishes to travel to control its flight path as well as selecting a desired landing area. It then propels itself by thrusting its body up and away from the tree, sucking in its stomach, flaring out its ribs to turn its body in a “pseudo concave wing”. Flying snakes are able to glide better than flying squirrels and other gliding animals, despite lack of limbs, wings, or any other wing-like projections, gliding through the forest and jungle it inhabits with the length being as great as 100 m.
The frilled shark is a living fossil shark species which looks like a hideous giant eel but is actually a shark. On January 21, 2007, staff at Awashima Marine Park in Shizuoka, southwest of Tokyo, were alerted by fishermen to a ‘strange eel-like fish with razor sharp teeth’. The fish was identified as a pregnant female 1.6 m frilled shark and was captured by park staff who were concerned that the shark appeared to be unhealthy. They took it out of the water and put it into a salt water tank where they filmed it and took pictures of it. The shark died a few hours after capture. The frilled shark is sometimes referred to as a living fossil partially because the species has changed little since pre-historic times.
Millipedes can be quite dangerous creatures, but the shocking pink dragon millipede takes the cake for its nastiness. This millipede shoots cyanide from its mouth. It is a spiny and toxic millipede aptly named for its bright pink color. These adult millipedes are approximately 3 cm long and live in the open on leaf litter. Because of their ability to create cyanide, the millipede smells like almonds (the common odor of cyanide).
Despite their name, the mantis shrimps are neither shrimp nor mantises, but receive their name purely from the physical resemblance to both the praying mantis and the shrimp. These creatures are sometimes referred to as “thumb splitters” because their claws are strong enough to split human appendages. These highly intelligent creatures are often monogamous and they get to know and regularly interact with their neighbors. The mantis shrimp also has the best eyesight in the animal world with 16 different photoreceptor types (compared to four in humans). But – what really makes these creatures badass is their ability to break out of aquariums by smashing the glass with their claws. It has a punch stronger than a .22 calibre pistol.
The Giant Amazonian Centipede can grow to over a foot in length. It is carnivorous, feeding on lizards, frogs, birds, mice, and even bats which it can catch in mid flight! It is also known to prey on tarantulas. The centipede has modified claws called forcipules which curve around its head and can deliver venom into its prey. The extremely potent venom, containing acetylcholine, histamine and serotonin (pain mediators), proteases and a cardiodepressant factor, is toxic to humans and causes severe swelling, chills, fever, and weakness. However, although bites are painful, they are unlikely to be fatal – nevertheless, this is a creature I don’t want to come into contact with. In the clip above you can see the centipede catching a bat in midair.
The 2007 edition of the Guinness World Records lists the cassowary as the world’s most dangerous bird. Normally cassowaries are very shy but when disturbed can lash out dangerously with their powerful legs. During World War II American and Australian troops stationed in New Guinea were warned to steer clear of the birds. They are capable of inflicting fatal injuries to an adult human. Usually, attacks are the result of provocation. Wounded or cornered birds are particularly dangerous. Cassowaries, deftly using their surroundings to conceal their movements, have been known to out-flank organized groups of human predators. Cassowaries are considered to be one of the most dangerous animals to keep in zoos, based on the frequency and severity of injuries incurred by zookeepers. If you think the picture above is scary, check out this image of its feet.
The Humboldt squid is a large, predatory squid found in the waters of the Humboldt Current in the Eastern Pacific Ocean. These squid hunt in packs of up to 1,200 and use their ability to rapidly change color to communicate with each other. Scientists believe that they are highly intelligent and use complex communication. Each tentacle is covered with suckers filled with razor sharp teeth which they use to drag their prey to their beaks. They often approach prey quickly with all ten appendages extended forward in a cone-like shape. Upon reaching striking distance, they will open their eight swimming and grasping arms, and extend two long tentacles covered in sharp ‘teeth,’ grabbing their prey and pulling it back towards a parrot-like beak, which can easily cause dramatic lacerations to human flesh. The whole process takes place in seconds. To make matters worse, these creatures love hunting humans – they do it very frequently and most fisherman in the area know of at least one or two friends who have been eaten by a pack of these monsters.
The immortal jellyfish (turritopsis nutricula) has to be item one on this list because of the fact that it is immortal. That isn’t hyperbole – it really is immortal. After reaching sexual maturity, this jellyfish is able to reverse its aging process and become a polyp again. The ability to reverse the life cycle is probably unique in the animal kingdom, and allows the jellyfish to bypass death, rendering the Turritopsis nutricula biologically immortal. Lab tests showed that 100% of specimens reverted to the polyp stage.

I want to reverse my lifecycle and become a kid again
fascinating, my favourites are the squid, and the immortal jellyfish, cassowarys are pretty cool too
kick ass list
that flying/gliding snake just might be the scariest thing i have ever seen in my life. im not too fond of snakes to begin with, but once they start flying at my face then its open season on the little bastards.
Very cool list, I had not heard of a few of these animals. And believe me, I don’t really want to run in to any of these animals either.
I couldn’t pick are favorite from this list, because I think they are all incredible. Fantastic list.
Any list like this that starts with the Komodo Dragon has got to be a winner!
I bet scientists are ALL OVER that immortal jellyfish’s DNA! …remember how they injected that bioluminescent jellyfish’s DNA into mice, and the mice started glowing, too? I see a pattern here…. . . .
that jellyfish kicks ass! nice list!
awesome list
Id like to mention the fact the it is thought that the saliva of the komodo dragon contains a bacteria that is extremely toxic. They usually bite birds or other animals and continue to follow them until that animal dies cuz of the toxcity of their saliva. The komodo dragon isnt affected by the bacteria cuz its blood contains some kind of antidote
Wow. Some of these creatures are amazing. Especially the last one, that’s pretty impressive really.
I don’t have a Komodo Dragon, but I do have a Bearded Dragon. That guy is a vicious killer. But he loves humans.
@Arsenal # 11
i heard the thing about the komodo dragon not having any actual “venom” and that it is only the highly deadly bacteria that live in its saliva that kill its prey. however, it was recently proven to be false. the info is from NatGeo so im pretty sure its legit.

No Honey Badger? Terrifying animal. Rips anything and everything to shreds and *****yses the weak points of its enemies – the testicles on a man – before attacking.
what about the number one badass creature the honey badger? They are awesome and totally fearless critters
Seriously interesting list – the shark, squid and jellyfish are paticuarly incredible
giant amazonian centipede….
oh my effin god… good thing we only got 3-6 inch centipedes here in asia..
Amazing list man. The immortal jellyfish’s name itself is so badass, it will make Staff Sgt. Max Fightmaster crap his pants. Great list.
This list is amazing. The only thing that was missing was David Attenborough narrating the whole thing to me.
theres already a similar list with the honey badger and bullet ant and stuff. kl list though
i juz got jizzed in my pants… greatlist…
i am astonished at the exclusion of humans from this – they are living creatures, and they’re badass!
Homo sapiens FTW!!!
@Joanne.. Humans are not on here because we say dumb things like “FTW!!”
being nerds doesn’t make humans badass.
Great list!
number one is pretty amazing.
great list loved it.
skipped some of the bugs though they creep me out.
Immortal jellyfish, our clue to immortality?
The flying snake is just a beautiful combination of physics and biology
and i’d like to know how the mantis shrimp packs such a punch
how is the frilled shark badass?
wow, that clip of the Humboldt Squid looked like the trailer for an alien shoot-em-up..
In the link on number 3 i think the person’s feet are more scary than the Cassowary’s…
Hells yeah! Giant African land snails are frickin’ badass!
I have three (I like in the UK so they’re nice and legal) and they are the most awesome pets. Mine are only about 8 months old but they’re already about 3 1/2″ long.
I think they’re pretty damn cute too
Tesla, Archimedes and Aeschylus are my snail babies and they kick ASS!
Having said that, I can’t imagine I’d want any of the other creatures on here as pets :s
Great list!
I remember seeing the frilled shark in my boyfriends magazine as one of the Earth’s most phallic looking creatures!!! Just thought I’d share that nugget of wisdom with you all!!!
First, I'll bet everyone who read your post had to scroll back up to check it out – lol. Second, what kind of magazines does your boyfriend read that has such stuff in it?!?
Another reason the komodo dragon is badass – one of them bit Sharon Stone’s husband on the toe.
I DEMAND BLOBFISH TO BE IN THIS LIST!!
i really like those shrimp, strangely charming creatures
Wow!!!!
Amazing list!
You forgot to mention that with the Komodo Dragons, their spit is acidic.
I first read #1 as immorral, had a weird 5 seconds thinking about what that meant untill I read the paragraph…. Imagination is often better than reality.
Great list. Stuff about nature and animals never gets old. The fling snake is amazing, unless one wraps it self around you as it is descending.
Cool list Jamie – a fave. Unsure what’s worse; flying snakes or giant toxic centipedes?
@Rufus (25): Pretty sure those mantis shrimp actually *****their claw. Has a locking mechanism so they can store up the energy and release it all at once. Think elastic band pulled to its max and then let go.
See…what they should’ve had was Flying Snakes on a Plane!
I think I am most afraid of that shrimp.
the peter pan jelly fish should be its name..
what about crocodiles?
crocodiles pretty freakin badass
and killer whales XD
wow!!! what a list. i’ve not heard of some of these & the pictures/video’s are amazing!! what a great, great list. keep up the good work. the squid is brilliant!! what sensational footage. thanks
Beer Drinking Giant Snails? I’m for that, definately!
The jellyfish also gets my vote, if I had that as a pet, it’ll never die on me and I won’t have to feed it right?
On the toe? That’s badass?
I enjoyed this list. Never heard of that pink millipede before. The color is more striking than shocking.
Just as a side note, the giant snail is so cool! I would love to have one as a pet.
That was Gary, right?
could you imagine a cassowary and an armored human fighting or something….
Humboldt Squid: It doesn’t have a single bone in its body but it can still kick your ass.
the fact that they can punch so fast UNDER WATER makes the mantis shrimp even more badass. I mean, it’s hard for humans to move underwater compared to on land. How fast would it punch if it did it on land?
On a side note-when I was a kid I was stung by a jellyfish. OOOOOOOOOOWWWWWWWWWWWW!!!!!!!!!!!!
sjees, I hope they’ll never extract that Immortal Jellyfish DNA and supply it as a pill to mankind, imagine everybody being immortal, doubling the population roughly every generation, give or take a billion…:-(
i think the feet of the guy holding the cassowary has the scarier feet!lol
Fedor Emelianenko should be in this list
I loved your choice for number 1! Great list!
I seriously looked around my immediate area with cold sweats after watching the centipede. Irrational? Couldn’t help it.
#1 is so BA I almost *****ed myself after reading it.
Gr8 list.
All of these animals are beautiful, though I would never wont to meet any of them…
also on the image of the BIRD foot, I couldn’t decide whose feet looked worse. the bird’s or the person holding it
“These are not necessarily dangerous or scary creatures”
aack. I beg to differ.
I look at the cassowary, and I think that it had to have evolved from a freaking dinosaur! Come on, someone agree with me!! Great list!
There can be only one… immortal jellyfish!
Wow..never want to run into that squid!
#1 kicks ass too. How about the hydra though? They’re ‘immortal’ too I think!
My thinking is that these animals are badass simply because they are each awesome in their own way. Nature is packed with so many wonderful creatures. I’m sure many will agree.
jellyfish= awesome! its only about 5mm though so not that awesome.
Fred #58 you are correct the hydra is in fact immortal but entirely bypasses the aging process.
