A hippo's skin is bulletproof. It can, however, be removed with a zipper located underneath the torso of the animal. If you plan on shooting a hippo, your best bet is seducing it first.
Nile crocodiles, lions and spotted hyenas are known to prey on young hippos. However, due to their aggression and size, adult hippos are not usually preyed upon by other animals. Cases where large lion prides have successfully preyed on adult hippos have been reported; however, this predation is generally rare.
1) Hippos are large semi-aquatic mammals, with a large barrel-shaped body, short legs, a short tail and an enormous head! They have greyish to muddy-brown skin, which fades to a pale pink colour underneath.
BBC News reports that the hippo is the world's largest land mammal killer. It's estimated that the aggressive animal with sharp teeth kills 500 people a year in Africa. Hippos can crush a human to death with their weight ranging anywhere from 3,000 to 9,000 pounds.
Big cats such as Lions and other animals like Hyenas and Crocodiles are the most common predators of the Hippopotamus, particularly of the young or sick individuals. It is because of this that females are thought to congregate in herds as larger numbers are more intimidating to hungry carnivores.
Hippos, with their sun-sensitive skins, are awake all night – out foraging far and wide for grass. All of their sleep therefore takes place during the day. Although hippos are often seen basking and sleeping on the banks of rivers, most of their sleep is actually taken inside the water – whether shallow or deep.
Although they primarily only eat plants—munching on about 80 pounds of grass each day—hippos are one of the most aggressive animals on Earth. They can snap a canoe in half with their powerful jaws, and they kill about 500 people in Africa each year.
The body may release stool from the rectum, urine from the bladder, or saliva from the mouth. This happens as the body's muscles relax. Rigor mortis , a stiffening of the body muscles, will develop in the hours after death.
The young of elephants, giant pandas, koalas, and hippos eat the feces of their mothers or other animals in the herd, to obtain the bacteria required to properly digest vegetation found in their ecosystems. When such animals are born, their intestines are sterile and do not contain these bacteria.
The zoo continued, "Hippos use their mouths to act tough, play, show affection and explore the world around them (we think Bibi likes the mouth massage!)"
Ungainly as it is, the hippopotamus is the world's deadliest large land mammal, killing an estimated 500 people per year in Africa. Hippos are aggressive creatures, and they have very sharp teeth. And you would not want to get stuck under one; at up to 2,750kg they can crush a human to death.
Hippos are graceful in water, good swimmers, and can hold their breath underwater for up to five minutes. However, they are often large enough to simply walk or stand on the lake floor, or lie in the shallows.
With their heads above water, the bulls frequently open their mouths wide as a show of dominance. Whether intentionally or not this shows off their weaponry. The enlarged canines, which are very sharply honed top on bottom, are solely used as defensive weapons - the only weapons (apart from their bulk) that they have.
A study lead by researchers at Yale University found hippos pooping in the Mara River in Africa are killing off the fish. Scientists found the hippo excrement not only kills off oxygen levels, but leaves behind chemicals such as ammonium and sulfide, which is also harmful to fish.

Of all the poops in the world, only those of Australia's wombats come out shaped like cubes. Like many animals, wombats mark their territories with small piles of scat. Other mammals poop round pellets, messy piles or tubular coils. But wombats somehow sculpt their scat into cube-shaped nuggets.
The excrements of hippos play an important role in the ecosystem of African lakes and rivers. Because there are fewer and fewer hippos, this ecosystem is in danger. Most of their days they spend relaxing together in rivers or lakes, far away from enemies and protected from the burning sun.
Adult hippos have thirty-six teeth, including two incisors, a canine, three premolars, and three molasses in the lower half of the jaw on both sides.
A single hippo can generate about 22 pounds of waste per day. The Cincinnati Zoo has two. With that much waste in a 70,000-gallon pool, it's a challenge to keep the water clean enough for visitors to actually see the hippos.
Forget Facebook: Rhinos get their gossip by sniffing feces at a communal latrine, a new study says. From the campfire to the water cooler, people have always gathered around to share the latest news. White rhinoceroses, it turns out, do the same thing—only their choice of meeting place is a giant pile of poop.
The tilapia in Hippo Cove serve multiple purposes. They help to keep the water clean by eating the hippo dung and they also eat the dead skin off of the hippos which keep them clean and free of micro-organisms. This is referred to as a symbiotic relationship.
Bonobos are the only non-human animal to have been observed engaging in tongue kissing. Bonobos and humans are the only primates to typically engage in face-to-face genital sex, although a pair of western gorillas has been photographed in this position.
It is often assumed that animals do not have sex for pleasure, or alternatively that humans, pigs, bonobos (and perhaps dolphins and one or two more species of primates) are the only species that do. This is sometimes stated as "animals mate only for reproduction".
But hippos split their 24 hours between grazing on land, then spending a considerable amount of time in rivers to cool off their bodies. It's in the water that they tend to defecate, their tails violently spraying their dung around.
Mating ritual evolved because it is advantageous for females to have choice of partners. If the female has sperm from more than one male, then sperm competition comes into play. After mating has taken place, males do various things to stop the female mating again.
In some species, males will perform ritualized movements to attract females. As the male flies over the female, he rotates his body and spreads his tail feathers, which flutter and collide to produce a short, buzzing sound.
This is likely because mouse females are able to infer mate quality from the males' scent mark deposits. The findings are reported in the Journal of Animal Behaviour. Many animals use scent marking to advertise their territory -- they urinate at strategic locations -- to communicate their social status and ownership.
The gestation period for this hippo species is eight months, so Bibi's official due date is sometime in March. Baby proofing and birth planning have already begun.
