Rhinoceros Horn

Today, I will talk about rhinoceros horn.

A rhinoceros is known to have a very hard skin, and a horn.

Actually, this horn is made of a protein called keratin, and there is no bone in the horn.

This is similar to hair (beard) or nails of humans, and if anything, it's closer to hair.

Therefore, even if the horn breaks, it will grow again naturally.

Since the rhinoceros horns are useful as herbal medicine, and the price can be higher than gold or platinum, rhinoceros poaching often takes place in massive.

By the way, bull's horns seem to be closer to nails.

サイの角（犀角）

今日はサイの角について話します。

サイは非常に硬い皮膚と、角を持っていることが特徴として知られています。

実はこの角はケラチン質というタンパク質でできており、中に骨などは入っていません。

人間で言うところの毛（髭）や爪と同じであり、どちからと言うと毛に近いそうです。

そのため、角が折れても自然にまた生えてきます。

サイの角は漢方薬としても重宝され、金やプラチナよりも高値になることから密猟が絶えないそうです。

ちなみに、牛の角はどちからと言うと爪に近いそうです。
