Top 10 Most Aggressive Animals

By aggressive I mean animals which can be provoked easily and will attack without warning. Not necessarily to humans, it can be any animal including others of its own species.
The Top Ten
1 Hippopotamus The common hippopotamus, or hippo, is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus.

Hippos are extremely territorial, don't get close or they may charge at you and impale you on their 2 foot long canines.
Males will often lock mouths with each other in a fight for a pod of females and females will fight in order to protect their calves. Hippos kill over 500 people per year due to the short temper they possess.

Strangely, hippos are too violent, much more violent than crocodiles. Lions will attack only if you're too close or if they are very hungry. Hippos won't mind chasing you the split second they catch the glimpse of yours.

2 Wild Boar
3 Saltwater Crocodile The saltwater crocodile, also known as the estuarine crocodile, Indo-Pacific crocodile, marine crocodile, sea crocodile or informally as saltie, is the largest of all living reptiles, as well as the largest riparian predator in the world.

Don't go near their eggs or risk having a one biting you in half.

4 Black Mamba The black mamba is a species of extremely venomous snake, a member of the family Elapidae native to parts of Sub-Saharan Africa.
5 Tasmanian Devil The Tasmanian devil is a carnivorous marsupial native to the island of Tasmania in Australia. It is characterized by its stocky build, black fur, and powerful jaws. Tasmanian devils are known for their fierce temperament and distinctive vocalizations that include screeches and growls. They have a strong... read more

They will fight to the death to defend their food. Unless you want to challenge, keep away.

6 Sun Bear
7 Wolverine The wolverine, Gulo gulo, also referred to as the glutton, carcajou, skunk bear, or quickhatch, is the largest land-dwelling species of the family Mustelidae.

"This animal should be #1 on the list. Easy. First off, Hippopotamus only attack if you invade their territory, most commonly water, whereas Wolverines will actively hunt for pray instead of staying in their territory waiting for something to enter which in the hippo's case would be a croc, big fish, zebra, or anything else that might enter it's territory in search of water such as a bison. A shark would only attack you if you if it smelled blood, were making noise, or attacked it which are specific reasons making it easy for a shark to avoid you. Also, if you weren't doing any of these things the chance of a shark attacking you is less than the chance of you being struck down by lightning. Lastly, and most specifically, a wolverine is obviously more aggressive and territorial than a grizzly. If a wolverine encountered a grizzly (A wolverine is near 1/3 the size of a grizzly), the wolverine would be the first one to attack although it probably wouldn't win."

8 Cassowary The cassowaries are ratites in the genus Casuarius and are native to the tropical forests of New Guinea, nearby islands, and northeastern Australia.
9 Cape Buffalo The African buffalo or Cape buffalo is a large African bovine. Syncerus caffer caffer, the Cape buffalo, is the typical subspecies, and the largest one, found in Southern and East Africa.

These animals are extremely unpredictable! Have you seen the battle from Kruger? These Buffaloes nearly kill a pride of lions. Not to mention that a baby buffalo had around 8 lions trying to suffocate it and it still survived. This animal needs to be at least on the top 2.

The animal that makes lions look like cowards. They may unexpectedly start charging at their target, horns forward and attack. This especially happens if there are calves nearby. They can kill up to 200 people a year. They also fight for dominance in a herd which.

10 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... read more

By far the most aggressive and deadly animal on this earth. Also, it is the only animal that destroys its own habitat and is known to be very cruel towards every other living species of this earth.

We are mammals which make us animals genius. And we kill and rob each other so we are the most aggressive.

What have we done to this world?

The Contenders

The power of lust gives these beasts the aggression that sends them absolutely insane when a rival male wanders into their territory. Armed with a 4 tonne body and sharp canines they don't mess around. Fights between these animals are a daily occurrence for these animals during breeding season.

12 Rhinoceros A rhinoceros, commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae.

Similar to the hippo, just bigger, slower and lacks the canines preferring tusks that can grow up to 3 metres long.

14 Honey Badger The honey badger, also known as the ratel, is widely distributed in Africa, Southwest Asia, and in the Indian subcontinent.

Sharks seem to fear the killer whale for a good reason. Killer whales have been known to kill sharks. They will try extremely hard to catch seals by even beaching themselves (able to get back in the water). They are very enduring, being known to chase their prey for many hours in an attempt to exhaust them. Then it's time to rip them apart.

16 Golden Eagle

I don't know if they just like to scare grizzly bears "for the lulz" or what? But you know what they have done? They've attempted many challenges including the Honey Badger and Grizzly Bears. These birds don't believe in the rule of predation, they will try to kill anything it seems.

The only case of one attacking a human was in golden eagle snatches kid
