海獺喜歡冰！海洋生物學家解釋了其中的原因 (Sea Otters LOVE Ice! But Why -- A Marine Biologist EXPLAINS)

- That's the kind of stuff that would probably make a dentist cringe. But sea otters have adaptations that make this no big deal. Their molars have six roots instead of four, like ours, and they're flat and rounded, perfect for crushing. Sometimes, wild otters will even eat some of the shells. This not only provides them calcium, but something called roughage. It's very good for the digestive tract. Taken from someone who has cleaned up their fair share of otter poop, it is unique. So unique that it has its own name, Sprite.
這種事情可能會讓牙醫感到恐懼。但海獺的適應能力讓這沒什麼大不了的。它們的臼齒有六根，而不是像我們一樣的四根，它們的臼齒又扁又圓，非常適合碾碎。有時，野生海獺甚至會吃掉一些貝殼。這不僅為它們提供了鈣質，還提供了一種叫做粗糧的東西。這對消化道很有好處從一個清理過水獺糞便的人口中得知，這種糞便很獨特。獨特到它有自己的名字 雪碧
