September 22 is globally celebrated as the World Rhino Day in appreciation of the 5 rhino species - Black Rhino, White Rhino, Indian Rhino, Javan Rhino and Sumatran Rhino. Three of these - Black Rhino, Javan Rhino and Sumatran Rhino - are critically endangered.
Some facts about Rhinos:- The name rhinoceros comes from the Greek words rhino (nose) and ceros (horn).
- Rhinos have existed on earth for more than 50 million years. - The first rhino ancestors appeared on Earth during an epoch known as the Eocene, along with a number of other mammal species. As odd as it may seem, the earliest rhinos lacked horns.
- Rhino horns are made of keratin, the same material that makes up your hair and fingernails.
- Some rhinos use their teeth – not their horns – for defense.
- White rhinos aren't white and black rhinos aren't black.
- Rhinos are faster than they look! They can run up to 30 – 40 miles per hour.
- A rhino’s skin is not as tough as it looks, and can actually be quite sensitive to sunburns and insect bites. That’s why rhinos like rolling in the mud so much!
