HIPPOPOTAMUS
SCIENTIFIC: Hippopotamus Amphibious
AFRIKAANS: Seekoei
SETSWANA: Kubu
ISIZULU: Imvubu
SWAHILI: Kiboko
Given name derived from Greek word "River Horse"
STATUS:
Vulnerable
THREATS / CONSERVATION:
Hippos are subject to unregulated or illegal poaching. In addition to addressing these common threats, the genetic diversity of hippos would need to be preserved to ensure the safety of the species. In May 2006 the hippopotamus was identified as a vulnerable species on the IUCN Red List,drawn up by the World Conservation Union (IUCN), with an estimated population of between 125,000 and 150,000 hippos, a decline of between 7 percent and 20 percent since the IUCN's 1996 study. Recently,Hippo's have been hunted for their huge tusk-like teeth to make ornaments,as poaching for Elephant Ivory has become more restricted due to increased protection.
The hippo population declined most dramatically in the Democratic Republic of the Congo.The population in Virunga National Park had dropped to 800 or 900 individuals from around 29,000 in the mid 1970s, raising concerns about the viability of that population. The decline is attributed to the disruptions caused by the Second Congo War. Poachers are believed to be former Hutu rebels, poorly paid Congolese soldiers, and local militia groups. Reasons for poaching include the belief that hippos are unintelligent, that they are a harm to society, and also for money. The sale of hippo meat is illegal, but black-market sales are difficult for WWF officers to track.
Hippo populations across the continent are currently threatened by loss of access to fresh water.

FACTSHEET
HABITAT:
The hippopotamus is a semi-aquatic mammal, inhabiting rivers and lakes,surrounded by grassland and light bush in sub-Saharan Africa in large groups of up to 40 hippos.
APPEARANCE:


The Hippo is a massive, semi-aquatic mammal with a total mass of up to 2,5 tonnes. It is able to walk under water on the river bed, and can remain submerged for five minutes.
The Hippopotamus, whose hide alone can weigh half a ton, is the third-largest living land mammal, after elephants and white rhinos.
An enormous, amphibious mammal with smooth, naked skin. An inflated looking body supported on short, thin legs. Huge muzzle (bigger in males), eyes, nostrils and little ears placed high on the head. Canines enlarged as tusks. Brown to gray purple with pink underparts and creases, short bristles on head, back and tail.
The hippo's proportions reflect its sedentary, amphibious existence. Its plump and bulky body is set on short, stumpy legs, with each foot having four toes. Although webbed, the toes splay enough to distribute the weight evenly over each toe and therefore adequately support the hippo on land.
With very thick skin, especially over the back and rump, the grayish-brown body is almost completely hairless, with only a few bristles around the mouth and the tip of the tail. The hippo has neither sweat nor sebaceous glands but does have unique glands that produce a viscous red fluid, leading to the myth that hippos "sweat blood." The hippo relies on water or mud to keep it cool, and the red fluid may have a similar function, but it is often produced in copious amounts when the animal is excited.
Even though they are bulky animals, hippopotami can run faster than a human on land. Estimates of their running speed vary from 30 km/h (18 mph) to 40 km/h (25 mph), or even 50 km/h (30 mph). The hippo can maintain these higher speeds for only a few hundred meters or yards.
DIET:
The Hippo sleeps in or alongside the water during the day and at night forages for grass close to the water. Herbivorous; a grazer, it eats about 40 kg of preferably short grass nightly, mowing a 50 cm swath with its muscular lips.
Although there have been a few reported cases of Hippo eating meat,and even cannibalism,they are not suited for a carnivore diet.Such reported cases,usually attributed to aberrant behaviour of nutritional stress.
BEHAVIOUR:
Hippos spend most of their days wallowing in the water or the mud, with the other members of their pod. The water serves to keep their body temperature cool, and to keep their skin from drying out. With the exception of eating, most of hippopotami's lives—from childbirth, fighting with other hippos, and reproduction—occurs in the water.
Hippos leave the water at dusk and travel inland, sometimes up to 8 kilometers (5 mi), to graze on short grass, their main source of food. They spend four to five hours grazing and can consume 68 kilograms (150 lb) of grass each night.
The diet of hippos consists mostly of terrestrial grasses, but they spend most of their time in the water. Most of their defecation occurs in the water, creating allochthonous deposits of organic matter along the river beds. These deposits have an unclear ecological function. Because of their size and their habit of taking the same paths to feed, hippos can have a significant impact on the land they walk across, both by keeping the land clear of vegetation and depressing the ground. Over prolonged periods hippos can divert the paths of swamps and channels.
Adult hippos are not generally buoyant. When in deep water, they usually propel themselves by leaps, pushing off from the bottom. They move at speeds up to 8 km/h (5 mph) in water. Young hippos are buoyant and more often move by swimming, propelling themselves with kicks of their back legs. Adult hippos typically resurface to breathe every 4–6 minutes. The young have to breathe every two to three minutes. The process of surfacing and breathing is automatic, and even a hippo sleeping underwater will rise and breathe without waking. A hippo closes its nostrils when it submerges.

Hippopotami are territorial only in water, where a bull presides over a small stretch of river, on average 250 meters in length, and containing ten females. The largest pods can contain up to 100 hippos. Other bachelors are allowed in a bull's stretch, as long as they behave submissively toward the bull. The territories of hippos exist to establish mating rights. Within the pods, the hippos tend to segregate by gender. Bachelors will lounge near other bachelors, females with other females, and the bull on his own. When hippos emerge from the water to graze, they do so individually.
Hippopotami appear to communicate verbally, through grunts and bellows, but the purpose of these vocalizations is unknown. Hippos have the unique ability to hold their head partially above the water and send out a cry that travels through both water and air; hippos above and under water will respond.
Adult hippos are hostile toward crocodiles, which often live in the same pools and rivers as hippos. This is especially so when hippo calves are around. Hippos have been known to be aggressive towards humans, and it is often claimed that hippos are the deadliest animal in Africa; however, according to Smithsonian Magazine, while the animal is very dangerous, reliable statistics for this are unavailable.
Threat Display: Water scooping, where a hippo appears to be mouthing and gulping the water, usually with tightened or staring eyes. Snorting, mock charging or full blown charges which can be followed up by actually leaving the water. Head shaking and chasing other hippos. Exhaling explosively above or below the water surface.
To mark territory, hippos spin their tails while defecating to distribute their excrement over the greatest possible area. Hippos also urinate backwards (are retromingent), likely for the same reason.
Hippos rarely kill each other, even in territorial challenges. Usually a territorial bull and a challenging bachelor will stop fighting when it is clear that one hippo is stronger. When hippos become overpopulated, or when a habitat starts to shrink, bulls will sometimes attempt to kill infants; sometimes female hippos will kill the bulls to protect their infants, but neither behavior is common under normal conditions.
Gaping: Hippos have a wide variety of reasons for gaping. One is a genuine yawn where the jaws are opened widely, often with the hippo male or female stretching up with its head out of the water. It is as well a standard threat display, exposing the obviously large lower canines (In a male, the lower canines have been known to grow to 3 feet in length). Gaping is often used in play between calves or between calves and adults, where the gape is followed by a pushing jostling competition.
BREEDING:
Cows give birth to a single young in shallow waters, after a gestation period of 8 months.The calf is often hidden in reeds for a few days by the mother, after which she and her baby rejoins the herd. Females reach sexual maturity at the age of seven to eight years. A female can produce up to ten young during her lifespan of approximately 35 years in the wilds. It is a myth that the mother carries her calve. What happens is that in cold conditions a young will rest the front part of its body onto that of an adult to sun bathe; due to their smaller body mass the young loses body heat faster than adults.
Most mating occurs in the dry season, always in the water, when populations are concentrated. Calves are hidden,not only from predators,but from territorial males looking for any chance to mate with the mother.There has been documented evidence of adult male Hippo's killing calves.
PREDATORS:
Adults:HUMANS
Calves:Lion,HUMANS. Male Hippo's [Breeding-related only]
HIPPO BYTES:
It was considered a female deity of pregnancy in ancient Egypt, but in modern times has been wiped out of that country because of the damage it inflicts on crops.
Did you know that Hoppo's are more closely related to Pigs than Horses as their Greek name, "River Horse" implies.
Its is now over the last decade or so,believed that Hippo's and Cetaceans,ie Whales,Porpoises etc,are thought by a few experts to be related,as both share a common Prehistoric ancestor.
During the catastrophic Indian Ocean Tsunami & Earthquake of December 24th 2004,a Hippo calf was washed out to sea by the Tsunami off the Kenya coast,and was subsequently rescued..and what followed,was a remarkable tale of friendship bewtween two very different creatures.Link below.
