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.

Humboldt squid…. how dangerous they truly are to humans is up for debate. They are dangerous to fishermen certainly, but if you accept that they are intelligent enough to communicate terror to each other, then you take a look at exactly how those fishermen are catching them, you might understand why they’re prone to attack. There’s been a study or two on it. It’s not so much they like to hunt humans, it’s just that the fishermen ***** them off.
Fantastic list! Hadn’t heard of quite a few of these so thanks for educating me on badass creatures!
Awesome list! I want one of those snails, they’re kick-ass!
oh my.. how i wish human, too, can reverse its age!
awesome………
I really hate to be an *****, but this list is identical to the one on atom.com covering the same topic. Down to the pictures and everything. I always have liked and appreciated that listverse was original, and usually other sites copied and took its material- not the other way around.
wheteher those nautical tales are true or not the thought of getting eaten by one of those monsters is pretty horrific; it is possible, they are huge
I think it’s bizarre to see bugs like the centipede eat things like mice and bats. The centipede reminds me of that scene in Peter Jackson’s King Kong when the crew get devoured by the giant bugs
Great list. I think I will definitely wear shoes when I go out to the garden today. No fuschia millipedes between my toes thank you very much…:)
Thats a huge freaking snail and a terrifying snake. Strong mantis shrimp…Gosh thats a huge ferlucking centipede! Thats a lot of squid…and that is a talented jelly fish!i wish i could do that! Awesome list man.
well..finally there is….. a good list!!
but you should change no.#2 Humboldt Squid
its not impressive as the cuttelfish you should see it
its a MUST SEE
Cuttlefish are sometimes referred to as the chameleon of the sea because of their remarkable ability to rapidly alter their skin color at will. Their skin flashes a fast-changing pattern as communication to other cuttlefish and to camouflage them from predators. This color-changing function is produced by groups of red, yellow, brown, and black pigmented chromatophores above a layer of reflective iridophores and leucophores, with up to 200 of these specialized pigment cells per square millimeter. The pigmented chromatophores have a sac of pigment and a large membrane that is folded when retracted. There are 6-20 small muscle cells on the sides which can contract to squash the elastic sac into a disc against the skin.

I was actually shocked at how frigging awesome I found this list to be. I was expecting it to be pretty cool but I think it blew my mind two or three times. Holy crap.
good list, but i had recently read a similar one on cracked.com which included some of these animals…kinda took away the thunder of this list. ah well, still a very fun list.
Several of these could be described as more creatures that defy evolution.
awesome list! loved the sea animals in this one-the ocean contains so many fascinating secrets!
Great list, but I think it should include the Wolwerine, or Carcajou. It’s one mean beast, who goes for the jugular when it attacks (and it’s not a metaphore!) It was the devil’s reincarnation, nothing less, in North American Native’s religion.
http://en.wikipedia.org/wiki/Carcajou
couple of these seem to be copied from cracked
I have just a few words – holy sh*t!
This is a fascinating, yet scary, list. I’ll be looking up where the habitats of the flying snakes are…that literally made me cringe.
I am tempted to email this list to my snake-phobic friends….
I am wondering what naturally keeps the immortal jellyfish population from overpopulating? If they can reverse aging to prevent death, are there millions of these lucky bastards out there?
@fifthsonata (78): i wondered about that too, so i looked it up. i found this site. you may wanna check it out if your interested in the immortal jellyfish population: http://www.abovetopsecret.com/forum/thread433154/pg1
Fantastic list!!! I love the immortal Jellyfish
Aren’t ALL squid predatory?
I think that the amazing thing in the immortal jellyfish is that it is not only immortal, but it has the smartest way of being it. I mean: being forever old, for example, would be a really bad way of being immortal!
This returning young, then aging again is something really great!
You may think it’s cool to live forever, but it sucks freight containers of camel dicks. Somebody kill me… Please. I tried to get that ***** squid to eat me, told him his mom did interracial bukkake squid gangbangs for crack rocks, but he didn’t understand. He was sofa king retodded. Somebody please kill me… Oh, the salty tears of unfathomable sadness…
@Harvey the Immortal Jellyfish (83): ***** dude, wtf?
@Reverend Lisa (81): some probably just scavenge, but idk for sure
I just ate a plate of stir-fried Mantis Shrimp today. They taste awesome, the flesh is very tender, and I didn’t know how they looked like until now.
@archiealt (20): This list is amazing. The only thing that was missing was David Attenborough narrating the whole thing to me.
(Chineapplepunk’s boyfrend should like it too:)
@byjimini (15): 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.
Whoever created this badger must have been crazy
Wow Nature rules !!!
Never heard of the Immortal Jelly fish or the Shark.
I’d heard of all of them except the frilled shark. That’s a pretty neat-looking thing!
Sharks are cool. I’m scared of them though.
Fantastic list! I went back up to verify it was Jfrater but no surprise there.
This is an extremely interesting list! Never heard of the immortal jellyfish though; very fascinating.
Great list, Jfrater. It took me a long time to read it, because I kept looking up things, then looking up more stuff. I’m not done yet. To me, that makes a good list. It gets my research juices flowing. Thanks.
It’s a nice list, but I’m not a fan of the sensationalism used for the Humboldt Squid part. Everyone knows the reputation of “fishing stories” and the evidence definitely seems to point to the perceived threat of those squid to humans being false. They are wild animals, so anything can happen, but they do not make a habit of preying on humans. This article will probably clear that up for people.

Finally!!! I knew Benjamin Button was real! Even if is in gelantenious form.
I’m at work in a nature park in the middle of cassowary country – and we have one in our park! It takes 3-4 people to herd the damn thing into a special cage if we need to get into clean or anything. They are rather strikingly beautiful though!
Awesome list, Jamie! I love anything having to do with animals, but this was particularly interesting. Thanks for another great list!
the komodo dragons actually inject poison they found out recently not bacteria
Now just imagine Flying Snakes on Mutha*****in’ planes.
That is the most badass thing ever!
I was snorkeling in Japan (okinawa) and I caught a mantis shrimp, When I tried picking it up with a net to take it back into the water (I put it into a bucket) It tore a hole in the net so I had to dump the whole bucket into the water
. When it strikes it makes a really loud POP noise.
@Sarah (65):
I really hate to be an *****, but this list is identical to the one on atom.com covering the same topic. Down to the pictures and everything.
Um, Sarah… If you really hate to be an *****, you’ll have to try a little bit harder not to be one.
Not that Mr. Frater needs me to defend him, but out of curiosity, I checked out your claim on atom.com. There were three on their blog that also appeared here on JF’s list. Hardly identical. The accompanying text is completely different, atom.com’s being fraught with profanity and “like, you know, like MTV Generation- speak.” As for the pictures, they’re the first ones that appear if you do a google images search.
Methinks (got it from Astraya) there’s something inside you that actually ENJOYS being an *****.
Awesome list, JayFray.
I’ll expect some nightmares tonight!
Methinks I’m a role model now.
@astraya (101): Methinks I’m confused as to whether youthinks you’re a role model of an *****, or of a methinker.
@Maggot (102): methinks of a methinker
Regarding the opening paragraph I’m pretty sure you’re not supposed to put the word “very” in front of unique.
The humboldt squid is highly intelligent.
Yup, that’d be why it’s attacking a camera on the video, real Mensa member that one
The Curious Case of Immortal Jellyfish
The immortal jellyfish cannot truly be immortal. Yes it can revert to infancy but how many times can it do this before the telomeres of its DNA begin to unravel? Can it reverse mortal wounds like from a boat propeller or tiger shark?
Sorry the list is not complete without a badger on it. They are as badass as the come.
Fascinating list. This one is probably one of my favorites. I really didnt know about any of these other than the Komodo dragon. Alos, the Immortal Jellyfish is amazing, thats all I can really say about that…Amazing. Also, arent some turtles and some amphibians similar in that after maturity they dont age like us humans…and technically (without injure or disease) can live forever? I believe the tortoise is one of such animals…if anyone knows what I’m talking about that be great to hear a little more on the subject.
awhh, the Immortal Jellyfish is siiiick!
that’s hecka cool.
Where the heck is Chuck Norris?!?!
Chuck Norris destroyed the periodic table, because he only recognizes the element of surprise.
#7 is just scary looking. Damn.
Does anyone know what language is being spoken in the flying snake video?
Chuck Norris once ate a whole cake before his friends could tell him there was a ***** in it. Alright, I digress.
The underwater creatures are the most badass
great list!
another badass animal would be the snakehead fish
its huge, it has teeth, it eats anything it can get its teeth on, oh and it can breath out of water.
Fantastic list!
Afreeken-mazing list!!!!
117: HOMER SIMPSON.
Totally agree! Northern Snakehead would of fitted perfectly in this list.
It gets into a river takes over and destorys most of the population. It can also live on land for im not sure how long but a good bit!
Banned from almost ever country except its native one?… china or something
