Rhinoceroses

The Convention on International Trade in Endangered Species made trading ivory illegal in 1989. Because both male and female African Elephants have ivory tusks, they are often the unfortunate subject of poaching.

they live in open Savannah because that is where they graze

No.

Their skin if fairly similar to elephant skin.

It may look scaly because they really like their mud baths, which offers some protection against the fierce sun and stinging insects.

aslong as it feels like it. it is not up to the rhino, it is all in its genes. i recomend you stay in school and take science as you should know this. it is very basic knowledge

The Rhinocerous are prey. Predators eat meat but rhinorcerous eat vegtables and fruit. I'm not saying if you see a rhinocerous go and pet it just cause it won't eat you. It is a very big creature and is scared easily.

Black rhinos live in southern and Eastern Africa. White rhinos also live in eastern and Southern Africa. Hence, their ranges mostly coexist.

A rhino has a horn (or 2 depending on the species)

The white rhino is the largest species of rhinoceras.
The white rhino. White rhinos can weigh nearly three tons, to around 3000 pounds for the black rhino. Some males can grow much larger than this, some white rhino bulls have reached nearly four tons, and a few black rhino bulls approach two tons (4000 pounds).

Rhinos are known for their horns on their noses that help protect them from others. They also have thick skin that which protects them from the thorns and insects.

People hunt them for their horn, which is thought in many places to have medicinal properties. although this is not true, they are still killed because a horn can be sold for a lot of money to people...

about 1billion in Australia alone

Black rhinos like to live in open plains, sparse thorn scrub, savannas, thickets, and dry forests, as well as mountain forests and moorlands at high altitudes.

No they do not because of their mass and large body so they don't over heating meaning no pubic hair.

The rhino is slightly heavier but the hippo is longer. Hippo's teeth can measure 50 cm. rhino's hor is twice as big and rhinos are more aggressive. I'll say the rhino will win in a slight advantage.

The Rhino not only needs water to drink as most all living creatures do. But they also use water as a major part of their habitat. They need to wallow in muddy areas often, and usually do so during the heat of the day. During droughts Rhinos can go for up to five days without drinking water directly. But they still need to wallow in mud, to protect their skin from insects or parasites and the mud helps to keep them cool. If the weather is so dry that the mud is not available they will wallow in dust. For more details, please see the sites listed below.

A young rhinoceros is called a calf, just like a cow or whale.

I would estimate that there is about 65 left worldwide, most of them are thriving in Ujung Kulon National Park (Indonesia) however the few individuals left in Cat Tien National Park (Vietnam) I personally don't think will have a chance of survival because the country is corrupt after their civil war.

Regularly it drinks twice a day if water is available, but if conditions get dry it can live four or five days without water. It spends about half of the day eating, one third resting, and the rest of the day doing various other things. White Rhinos, like all species of rhino, love wallowing in mudholes to cool down.

They don't die from laying eggs, but from an evolutionary standpoint, there is no reason for a species to live past an age when it can reproduce. Almost every species on the planet dies at about the age when it can no longer reproduce, butterflies included. Humans have artificially extended our lives with modern medicine, making us one of the few exceptions to this rule. (thank God for that!) :)

All rhinos migrate because they have to look around for water.

A Black Rhino is pregnant usually between 419 and 478 days, or 15 to 16 months. The mother will give birth to a single calf, weighing in on average 35 to 50 kg, (about 80 pounds). The calf will stay with it's mother anywhere from 2 to 3 years, and sometimes, if the calf is female they may stay longer, and form a family type group of females. For more details, see the sites listed below.
they will be pregnant for 15 to 16 months (460 to 490 days)

can run up to 40 mph
about 11 mph if feels in danger or if you or another animal "tresspasses" on it's "land"
According to "The Mammal of the Southern African Subregion" by Reay H. N. Smithers, the white rhino (ceratotherium simum) trots at about 25 kmph and gallops up to 40 kmph.

Giraffes learn how to find food and water. They also learn to run away from predators. These two things are taught to them by their parents.

In the US, the best place for the public to find rhinos is at public zoos. Most big zoos have at least a few. These include the zoos in Birmingham, the Bronx, Cheyenne Mountain, Cleveland, Cincinnati, Dallas, Des Moines, Los Angeles, Memphis, Miami, Pittsburgh, San Diego, and San Francisco. Disney's Animal Kingdom in Orlando also has rhinos.
