A rhino's horn is very valuable because they are used to make daggers and are made of keratin. Keratin is found in hair and is rich in minerals and calcium so it is hard wearing and durable. It is illegal to hunt a rhino for their horns because they are an endangered species.
Part of the reason is the demand in Asia, where the horn is used in traditional Chinese medicine. A kilogram of rhino horn now goes for $60,000 on the black market. That's $1610 an ounce for the rhino horn. The rate of their decline is truly astounding: in the decade of the 1970s alone, half the world's rhino population disappeared. Today, less than 15 per cent of the 1970 population remains an estimated 10,000 to 11,000 worldwide.
The horn from a rhinoceros is considered valuable because the animals are nearing extinction and should not be killed for their horns. Some cultures believe these are a sign of good luck.
Because some ignorant people believe that the horn, reduced to powder, is an aphrodisiac or a cure for erectile dysfunction.
they are used for medicine that don't work and are also made into daggers.
yes
because people want to kill them for their horns.
Someone will probably improve this answer, as it's not clear what you mean: Do you mean 'What part of a Rhino is hunted for it's value?' because that would be it's horns. Lots of different animals get hunted for different parts of there body, for example, hunters hunt deer skin, but not rhino skin. They hunt rhino horns, but not deers horns. Lots of different animals have different values to their body.
A rhino will win because a rhino has horns.
With their horns.
An Indian Rhino has only one tusk and the African Rhino has two tusks.
they normally have 2.
the hunters
Since a rhino's horn is made out of hair, a rhino does shed its horn. Some horns are even kept as souveniers for some people.
Most likely a rhino when the rhino knocks the lion out with its big horns.
Not horns as such (like you would find on a rhino). but - there are 'horns' on some lizards, such as some chameleons.
it lowers its horn and charges
Probably a narwhal or a rhino
