Top 10 Worst Animals in the World

The Top Ten
1 Mosquito Spanish for "small fly," mosquitoes are insects that have been known to cause various diseases. A sample of diseases caused by mosquitoes: malaria, yellow fever, Chikungunya, West Nile virus, dengue fever, filariasis, Zika virus.

They inject you with their own saliva when they bite, leaving an annoying bump on wherever they touch their disgusting noses. I would be fine with them biting me if they didn't leave itchy infections

Unlike other animals, factually, mosquitos serve no purpose! They exist because they can, and give barely any nutrition, they aren't food, they barely pollinate anything, and therefore, I wouldn't care if they went extinct.

Mosquitoes are not only a nuisance to us, they also spread diseases and kill us. They make high-pitched whining noises that give you the same chills that nails on a chalkboard would when they fly around your ear, and they fly away when you try to kill them. They think that after everything they've done to the human species, they still have the right to live in our houses, forcing us to go to bed in fear of getting bitten.

2 Human Humans (Homo sapiens) are the most abundant and widespread species of primate, characterized by bipedalism and large, complex brains. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions... read more

Excuse me? I think humans are great. We are also humans. Although we do do some bad stuff sometimes, we aren't annoying. (Well some may be annoying but not all.) people like Jesus are great! Wished this wasn't here.

I feel like the reason this list exists is purely to highlight the killers of humans and humans themselves. The human way of life is what's wrong. But on top of that, we fight with ourselves. Not for survival, because of conflicts! We kill each other for more ridiculous than other animals. Some of us treat other animals as lower beings and refuse to consider ourselves as the same. What does life revolve around? Us! And the reason many other animals still thrive is because of us. That may sound like it makes humans good, but frankly, that's not true. It makes the people who do it good, but makes the species as a whole worse. They survive because we pity/care for us. It makes no difference but morally, they should be allowed to survive because they're adapted to do so, not because we didn't destroy their homes. The worst thing is that you can't even blame humans, but rather the race itself. We are adapted to live in environments that are adapted for us and a select few other animals. You could hate yourself every day, but there's nothing you can do about it. You are a human, the animal that pollutes the earth more than necessary, kills other animals and treats others of its kind badly too. There's nothing that could change that. Even if every human was a good person, humans would still be the worst animal.

3 Fly

Ahh flies, the creature that serves the one purpose in life... make life worse one around them! Like, really, what is the point of them? They're gross, they contaminate, the don't even server as food for most creatures. Sure, frogs need them, but they can just eat other insects. Flies do nothing but fly and make an annoying sound. Why can't they just leave us alone! All they're babies, disgusting.

Flies are annoying and gross. They get in your food and make it all yuck. They fly around animal droppings and make annoying noises. Watching them fly around is bad enough, I'd be surprised if anybody likes flies.

Flies are one of the few animals that make me lose my appetite. They are worthless and disgusting, but I do appreciate that they serve as food for higher animals.

4 Leech Leeches are segmented worms that belong to the phylum Annelida and comprise the subclass Hirudinea. Like the oligochaetes, such as earthworms, leeches share a clitellum and are hermaphrodites.

Only good for medical purposes. Otherwise they are disgusting and terrifying. Who wants to find a leech on their body? Nobody.

Not all leeches are harmful. Maybe some leeches are bad but in some cases, they use it for the medicinal properties as it suck the bad blood that cause diseases.

What if you were a leech? They have to eat to survive because if they didn't eat they'd die. I mean you'd think that's good but not if you were a leech

5 Hyena Hyenas or hyaenas are any feliform carnivoran mammals of the family Hyaenidae /haɪˈɛnᵻdiː/. With only four extant species, it is the fifth-smallest biological family in the Carnivora, and one of the smallest in the class Mammalia.

Hyenas are lazy cowards, they steal from other predators because they're too lazy to hunt themselves, always aim for the babies because they're too scared to go for the mother or herd, they eat alive making the prey going through extreme pain, they're laugh sounds like the devil choking, they're the ugliest animal on earth, sisters kill their sisters and bully their brothers as babies, if it weren't for their bite force, they'd be the worst predator on earth because they're so small and useless.

These animals are nasty, filthy vermin. I absolutely dispise them. They eat alive, they steal from other predators, they always attack baby animals, they're disgusting laugh that sounds like the devil choking. Whoever likes hyenas is mentally stupid and retarded.

Aw. One video where I saw this hyena bit a dog. I just want it go through that screen and stand up for dog and teach that hyena a lesson.

6 Termite Termites are eusocial insects that are classified at the taxonomic rank of infraorder Isoptera, or as epifamily Termitoidae within the cockroach order Blattodea.

Termites suck. Pigs are on this list and they don't suck they're amazing and the same with rabbits I hate whoever put rabbits on the list.

A swarm of angry termites can destroy a tree within 20 seconds. I wonder how long it takes for them to destroy a wooden house...

They killed my father

7 Tick

The absolute worst. Be careful when walking in the forest, always wear clothes that cover your arms and legs. Ticks can give you diseases that could kill you.

Foul creatures. They spread disease and few animals eat them. They are parasites that are stressful to remove from an irritated dog. Truly disgusting to look at

Ticks are the worst. (hyperbole, of course, mosquitos are worse). But it is terrifying to see you have one attached to you. And they can dig in? and get stuck in there!? No. bye. I am leaving earth does anybody have a space ship

8 Wasp

Let's look at wasp vs bees

Bees pollinate and help the environment. They help food grow and make honey. And we wouldn't have the bee movie memes without them.

Wasp are just asses. They suck. They don't help the environment or anything. They don't make memes and they serve no purpose on the planet. They're just useless ass bees.

I remember getting stung by a wasp when I was about 4 (which was 2012).
I was a at a car boot and (my dad? ) got some sweets. I ate them, and suddenly, a wasp came and stung me! I was crying.
That's why I hate wasps so much.

I have an uncontrollable fear of bees, wasps, and hornets ever since I was a kid. Thanks to my evasive attitude towards these nightmares, I've never gotten stung by them.

9 Jackal The jackal is a small omnivorous mammal of the genus Canis, which also includes the wolf and dog. While the word "jackal" has historically been used for many small canids, in modern use it most commonly refers to three species: the closely related black-backed jackal and side-striped jackal of sub-Saharan Africa, and the golden jackal of south-central Eurasia.

If they are like foxes, they do suck, jackals aren't even known much. I couldn't find any other animal here to put on the list so here you go.

Ikr, jackals suck. They're stupid and whoever likes them is an idiot. Lol they always go for the baby animal instead of the adult because they're too weak and they're too much of cowards.

I hate it when people call jackals cute!
its just an animal.
Why can't people see the psychical side of this thing for once.

10 Rat Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, Rattus norvegicus.

How are monkeys worse than rats? These rodents do nothing but spread disease. They were responsible for the Black Plague and they disgust me. Their smaller counterparts, mice, are better. Worst animal ever.

Those guys are disgusting, while the nice animals extinct they would grow much more, they exist in sewers and go anywhere, they are such disgusting creatures.

The only reason they spread disease is because of their fur. They had no actual intention. On the other had, humans use lab rats and ruin their lives.

The Contenders
11 Lice

I've gotten them twice before. Once it got my family the second time I got them out secretly somehow (they just, disappeared after combing for a couple weeks)

They just decide to go have babies on your HEAD and don't leave unless you get them out.

UGH. I had such a traumatizing experience with them. Hate lice.

12 Monkey Monkeys are haplorhine primates, a paraphyletic group generally possessing tails and consisting of approximately 260 known living species.

I believe in respect and love for all animals other than obvious vermin like bed bugs, and the Macaque monkey. They look like a cross between a human and a rat!

Monkeys are ugly. People who says that they are sweet, go hit yourself on the head with a baseball bat and go sit in the corner for being so dumb. Just look up Charla Nash. She can tell you about the true nature of a seemingly "sweet" animal such as a monkey. Plus, look at their faces! They're ugly as my sloth-faced ex.

Let's sing the I hate Monkeys song!

Curious George, Curious George, I want to throw you in a gorge.

Diddy Kong, Diddy Kong, Iconic, But been 'Round for far to long.

Boots, Boots, I wanna steel your lute.
But I can't promise I won't shot.

I hate Monkeys, I hate the. Stupid little bum holes who sit in a tree.

13 Flea Flea, the common name for the order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds. Fleas live by ingesting the blood of their hosts. Adult fleas grow to about 3 millimetres (1⁄8 inch) long, are usually brown, and have bodies that are "flattened" sideways or narrow, enabling them to move through their hosts' fur or feathers... read more

Honestly, I hate them more then almost everything on the list. They get on your animals, and if they get on you it is even worse. Can you avoid mosquitos by not going outside? Almost, they can't get you inside, but you are gonna have to go out of the house sometimes. Can you avoid fleas? Probably not, there are inside your house and if you don't spend a ton of money trying to kill them, then you will be stuck with them for a while.

I'm noticing a lot of bugs on this list. Fleas are here for kind of the same main reason as mosquitos. They suck blood, spread diseases, yeah yeah

I don't like fleas because they are harmful to animals by sucking there blood.

14 Bedbug

Bugs stopping my sleep. But they are an animal that wants to sleep with me in one bed so one point on redemption.

Bites you in sleep

15 Cockroach Cockroaches (or roaches) are a paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as pests.

The cockroaches are an ancient group, with their ancestors, known as "roachoids", originating during the Carboniferous period, some 320 million... read more

Monkeys, anacondas, jackals, hyenas, pigs, and more are higher than cockroaches on this list!?! What!? I have no hope for humanity anymore. Weird world we live in...

Even know cockroach's are harmless they are so nasty, they are always crawling around your home or garage and will never leave truly.

This must've been no. 1 it's disgusting, and annoying and creepy, it's everywhere, I hate those pests

16 Centipede Centipedes are arthropods belonging to the class Chilopoda of the subphylum Myriapoda. They are mainly carnivorous and they prey upon insects, spiders, small birds and rodents, and even other centipedes.

Seriously, people hate cats more than centipedes? Okay, let's throw a bunch of centipedes on the people who voted cats were the worst.

They're terrifying creatures. Similar to tapeworms, if you accidently eat one then its stuck in your body.. I just can't imagine having a 20 feeted creature crawling around in my body.

Don't hurt me but centipedes are interesting. Ugly, creepy, scary, horrifying, scarier than spiders, interesting.

17 Anaconda Anacondas are group of large snakes of the genus Eunectes. They are large snakes found in tropical South America.

They are extremely vicious and aggressive. They strangle you to death, which has to be the most painful form of death in existence.

However, they are only found in rainforests, so the majority of the human population are safe.

I don't like snakes because they can crawl where every the want, but I especially hate the venomous ones.

If this animal didn't exist the song Anaconda wouldn't be a song. Dang, I wish this weren't an animal.

18 Maggot

I don't wanna see this. Like seriously, they may seem harmless but they do something to your body. (At least I think so.) Worms are my least favourite living thing. I hate them, and maggots basically are worms! Normal worms do give life to plants, so I say they should exist,( if they actually give life to plants, otherwise, I wish they didn't exist )but not maggots!

I don't like maggots because they are so slimy and wormy and I don't like worms at ALL, they are helpful but disgusting.

I hate them so much

19 Tapeworm

Another kind of worm. Seriously, they are so distrusting! I do say they should exist because they give life to plants, but I never want to see one.wished plants didn't need worms. I also don't exactly know if they actually need worms. If they don't, I wished they didn't exist. Sorry worms, but I just hate u. So sorry.

Tapeworms are vile, disgusting and deserve to burn in hell. They are probably the most filthy degenrates out of all the animals and are literally parasites that grow inside people. And people think Naked mole rats are worse, wow.

20 Fox Foxes are small to medium sized animals and belong to the Canidae family along with other animals such as jackals, wolves, and domestic dogs. There are 37 species of fox but only 12 are considered true Vulpes. A fox's prey is small mammals, birds, reptiles, frogs, eggs, insects, worms, fish, crabs, mollusks, fruits, berries, vegetables, seeds, fungi and carrion. Some of the best known species of fox... read more

Why do people hate foxes they are so cute and funny the reason the hunt things is to survive like how we eat chicken,salmon or bacon YOU haters are sick because all predators are hated because of their looks and that they hunt other animals while we humans hunt for sport I'm done with this hatred of innocent animals that did nothing. Also foxes if they're tamed they can be people's best friends this is why you need to remove the fox and other animals that are not DO NOT harm people! BYE #####'s

I do not know why people seem to like foxes, I mean they are just stupid animals that don't care about hurting wildlife. They suck, they are as stupid as cats are.

Not only are they an invasive species, but they also kill/eat your babies, spread rabies, etc.

21 Hornet Hornets are the largest of the eusocial wasps, and are similar in appearance to their close relatives yellowjackets. Some species can reach up to 5.5 cm in length.

They're scary and they need to die. They are useless and have no purpose in this world. They are evil and I hate them so much.

Hornets should be exterminated. Everything has it's place in nature, but these things are just the worst.

I don't like them. How could anyone put PANDAS and polar bears and cats and dogs on this list?! They're awesome!

22 Wolf The wolf (Canis lupus), also known as the gray or grey wolf, is a large canine native to Eurasia and North America. Over thirty subspecies of Canis lupus have been recognized, with gray wolves comprising the wild subspecies. As the largest extant member of the Canidae family, the wolf is distinguished from other Canis species by its less pointed ears and muzzle, a shorter torso, and a longer tail... read more

Wolves. The animal itself is okay... But it's just so overrated! All the little 5 year old fans are just so annoying! They have wolves as profile pictures, just obsessed! I mean really.. What's so special about wolves anyway? It just makes me want to smash my computer as if it was the fanbase's face! Everyone has opinions, and If I say I hate wolves then they start swirling a tornado of hatred! The dumb fans of this overrated animal can't even take opinions! that's how bad they are!

I hate wolves, not because of wolfaboos, but because of them, just them.
This animal never actually "saved" Yellowstone National Park. Honestly, they were removed because they were an invasive species. When they brought them back, sure they kept the elk population down, but now they're pretty much eating everything and anything they want there.
If they were to die out, it wouldn't be a problem. Sure, there would be an increase in hoofed animal population, but we could always introduce new species such as coyotes, bear, or even mountain lions.

23 Baboon Baboons are African and Arabian Old World monkeys belonging to the genus Papio, part of the subfamily Cercopithecinae.

They eat baby antelopes and sheep alive in front of their helpess and crying mothers.

24 Coyote Coyotes are canines native to North and Central America. They are highly adaptable and can thrive in a variety of environments, from forests and grasslands to urban areas. Coyotes have a similar appearance to domestic dogs but are typically smaller in size, with a bushy tail, erect ears, and a pointed muzzle. They are opportunistic omnivores, feeding on a diverse diet that includes small mammals,... read more

I can't believe I had to add this myself. These stupid things kill cats and dogs and when they kill farmer's sheep they don't even eat them. Worst animal ever along with hippos and eagles in my opinion.

They are related to wolves, what do you expect, coyotes just do the same as wolves like they are trying to be the same. Wolves suck too but a bit more than coyotes.

Coyotes make me gag

25 Pig A pig is any of the animals in the genus Sus, within the Suidae family of even-toed ungulates. Pigs include the domestic pig and its ancestor, the common Eurasian wild boar, along with other species; related creatures outside the genus include the peccary, the babirusa, and the warthog.

I think pig do not deserve the hate because some pigs are cute so I think the pig shouldn't be on this list because of how nice some pigs are to humans even though people hate them because they roll in mud. They roll in mud to simply cool off.

Eh, this is complicated. I don't necessarily like pigs, mostly because of my religion, but I don't hate them either...

They are disgusting animals escapally wild pigs in Texas and Germany they worse than mice there. Let's not forget the fact that pigs that were introduced by Columbus made many species extinct in the Caribbean
