Stones of Sea Otters

Today, I will talk about sea otters.

Although sea otters have a big appetite, they can't swim quickly, so they live on shellfish.

When sea otters eat shellfish, they slam it into a stone that is placed on their stomach.

Actually, sea otters are an only animal that uses tools except for primates.

Also, sea otters are very particular about stones.

In fact, after they decide their favorite stones, they will continue to use them.

In addition, they sometimes boast to other sea otters about their stones.

Basically, they store their stones in their sagging armpits, but some sea otters seem to store in specific places.

By the way, sea otters look very cute, but their sexual appetites seem to be very strong.

ラッコの石

今日はラッコについて書きます。

ラッコは大食いですが、泳ぎが苦手なため、貝を主食にしています。

貝を食べるときは、貝をお腹の上に置いた石に叩きつけて割ります。

ラッコは、霊長類を除いて唯一、道具を使う珍しい哺乳類です。

そして石にはこだわりがあり、お気に入りの石を決めたらずっとそれを使い続けるそうです。

お気に入りの石を、仲間に自慢することもあります。

石は基本的に、脇の下の皮膚のたるんだところに入れておくそうですが、中には決まった場所に置いて保管するラッコもいます。

とても可愛らしいラッコですが、性欲は異常に強いそうです。

• By the way, though sea otters look very cute, they are sexually aggressive.

  Balances the statement with 'though'.
  
  Do you mean aggression? Cause that's what they are known for I think.

Hmm! Sea otters have been recorded performing forced copulation on other animals.

Not exactly disturbing given that humans are equally problematic when it comes to sexual fetishes and desires.
