RHINO

SUMMARY

Rhinoceroses are large, herbivorous mammals identified by their characteristic horned snouts. The word "rhinoceros" comes from the Greek "rhino" (nose) and "ceros" (horn). There are five species and 11 subspecies of rhino; some have two horns, while others have one.

Because the animals' horns are used in folk medicine for their supposed healing properties, rhinos have been hunted nearly to extinction. Their horns are sometimes sold as trophies or decorations, but more often they are ground up and used in traditional Chinese medicine.

estimates that there were 500,000 rhinos across Africa and Asia at the beginning of the 20th century. Today, the group says, there are 27,000 rhinos in the wild. Poaching and loss of habitat have put all rhino species in danger of extinction.

Rhino horns are made of keratin, which is also the key component of human hair and fingernails. But the horns are not just dense clumps of hair. CT scans have shown dense mineral deposits of calcium and melanin in the core of the horn. The calcium makes the horn stronger, and the melanin protects it from the sun's UV rays,
