Hippo
The hippopotamus kills an estimated 500 humans annually, making it Africa's deadliest large mammal, surpassing lions, elephants, and crocodiles combined. This statistic, maintained by the African Wildlife Foundation, reflects the hippo's unique combination of territorial aggression, aquatic ambush capability, and a bite force of 1,800 pounds per square inch, sufficient to sever a crocodile in two.
Hippo aggression operates on principles that defy conventional zoological understanding. They attack boats without provocation, chase vehicles at speeds up to 30 kilometres per hour, and have been documented pursuing humans for distances exceeding 500 metres. A 2017 study in the Journal of Mammalian Behaviour noted that hippo attacks display a level of determination and persistence unusual in herbivores, with some individuals returning to the same location daily to await potential victims.
The male hippo's territorial displays involve opening the mouth to a 150-degree angle, revealing canines that grow continuously throughout life and can reach lengths of 50 centimetres. These tusks, combined with the hippo's ability to remain submerged for up to five minutes, create an apex predator that happens, inexplicably, to be a vegetarian. The hippo's aggression is not motivated by hunger but by sheer irritability, a temperament that researchers describe as perpetually offended by existence.
Tea
Tea's aggression manifests not through physical violence but through the systematic dismantling of societies that stand between the British and their preferred beverage. The Boston Tea Party of 1773, in which American colonists destroyed 342 chests of East India Company tea, triggered a sequence of events that cost Britain its most valuable colony. Tea had, in effect, provoked a war that reshaped global politics.
The Opium Wars represent tea aggression at its most nakedly imperial. When China attempted to stem the tide of British opium imports in 1839, Commissioner Lin Zexu destroyed 1,400 tons of the narcotic at Canton. Britain's response was disproportionate: 16,000 troops, 37 naval vessels, and a campaign of coastal bombardment that forced China to cede Hong Kong and pay 21 million silver dollars in reparations. All because the British wanted tea, and the Chinese wanted to be paid in something other than drugs.
Even in domestic settings, tea exhibits aggressive properties. The caffeine content of a strong cup of builder's tea (75mg) provides sufficient stimulation to fuel workplace productivity, industrial action, and the occasional strongly worded letter to the Daily Telegraph. Tea has been present at more British confrontations than any weapon in the national armoury, though it admittedly serves more as fuel for aggression than aggression itself.
