Are rhinos near sighted?
White rhinos are the second-largest land mammal and their name originates from the Afrikaan’s, a West Germanic language, word “weit” which means wide and identifies the animal’s mouth. Often known as the square-lipped rhinoceros, white rhinos have a square upper lip with almost no hair. Two genetically different subspecies exist the northern and southern white rhino, and are within two different regions in Africa. By March 2018, there are only two rhinos of the northern white rhino left, both which are female. They live in the Ol Pejeta Conservancy in Kenya and so are protected round-the-clock by armed guards. Their near extinction is because of decades of rampant poaching for rhino horn. The Safari Park has one of the successful conservation breeding programs for rhinoceroses under human care in the world.
One group, the Australian Rhino Project, is already trying to establish a White Rhino population in Australasia. Some experts think that captive breeding may be the most viable near-term solution, specifically for the distressingly rare Sumatran and Javan Rhinos. Maintaining them in zoos or breeding facilities keeps alive the hope they might one day be reintroduced to the wild.

Many of these have moved on to live in other facilities all over the world. Females are not territorial and move through large home ranges that overlap with many other females. Several male territories may lie inside a single female’s home range. Adult white rhino females are more social than black rhinos and often stay static in small groups of up to a dozen or so offering calves and subadults.
But while rhinos may look indestructible, their skin is in fact quite sensitive, especially to sunburn and biting insects. All rhinos like a good soak in the mud, but for Asian rhinos, this becomes vitally important to help them get through times of high humidity, when insects can be a problem. Rhinos may often share a wallowing spot without any fighting, as if it really is neutral ground. White rhinos may create their own shallow mud holes by rolling in watery depressions in the planet earth.
Rhino Eyes: Does Size Matter?
As Zoo guests, it’s easy to take notice of the beauty and strength of the animals, but studying how they use senses to see their world brings a deeper knowledge of their ability to thrive in the open. Reindeer in the wild are mostly within extreme northern climates, where in the winter you can find very short periods of daylight and in the summertime you can find very short periods of night. Having a tapetum lucidum during the winter months helps the reindeer navigate the landscape, permitting them to better see food and predators. Our regal African elephants communicate using incredibly low rumbling sounds that cannot be heard by the human ear.
This helps keep them safe from the poachers who might otherwise kill them for his or her valuable horns. However, this leaves rhinos susceptible to attacks from other animals.
- One study suggests that
- That is why, not unlike other hefty animals such as for example hogs and hippos, rhinos love to wade and roll in mud, which, after drying, acts as a barrier between the animal’s skin and environmental irritants.
- With eyes located on opposite sides of the head, rhinos don’t have good binocular vision like humans along with other primates do, and in addition lack color vision.
- Its eye falls somewhere within the size of a soccer ball and a basketball.
- both in the care of the Ol Pejeta Conservancy in Kenya.
Of course, when it comes down to it, introducing rhinos to Australia is really a pretty wild idea. Maybe my tongue is in my cheek, and I’m just looking to get other tongues wagging concerning the desperate dependence on rhino conservation.
Before we gave you a listing of rhino species which had gone extinct, with in-breeding partly at fault. What we didn’t mention was that there were other species which had keep coming back from the brink of extinction.
In 1996, Maurice and Mushin conducted tests on rabbits by raising their body temperatures and intraocular pressures and noted that while younger rabbits were susceptible to developing myopia, older rabbits were not. Some recent tests have revealed that myopia in a few animals could be improved with eye drops containing zinc, by increasing the activity of superoxide dismutase . Their eyes, in comparison to the rest of these body, are absolutely tiny. They’re ranked as one of the most poorly-sighted animals on the planet, up there with bats and moles. A Sumatran rhino’s eyes are small set alongside the size of its head and body.
