海獺超愛冰塊！但為什麼？海洋生物學家來解答！ (Sea Otters LOVE Ice! But Why -- A Marine Biologist EXPLAINS)
- Back to teeth. Let's talk about the most unique tooth in the ocean, narwhals. Also known as the unicorns of the sea because of their most impressive asset, their tusk. These tusks are actually a canine tooth that projects from the left side of the upper jaw through the lip and forms a left-handed helix spiral. Some males, about 1 in 500, actually have two tusks. Scientists are still debating and searching for the biological function of the tusk. And while the answer is still unknown, the leading theory is that it's somehow involved in a mating or breeding display because of the fact that males tend to have them more often than females. However, recent analysis has shown that the tusk is a highly innervated sensory organ with millions of nerve endings. So, it appears that this tusk is some sort of sixth sense that helps the animals feel around their dark, wintery, cold world. There are very few tusked animals in the world and only one other tusked marine mammal. It just so happens to be my favorite animal of all time, the walrus. Just like narwhals, the tusks of the walrus grow throughout their lives. They're basically modified canine teeth. They can reach about a meter in length and the root of that tusk grows very close to the sinuses in the walrus. The depth of these canine roots makes dental health for walruses extremely important because they can easily break or chip tusks. And if those tusks get a break or a chip, an infection, an abscess, that infection can very easily make its way up to the sinus and even into the brain. In the beginning of the video,
回到牙齒。讓我們來談談海洋中最獨特的牙齒--獨角鯨。獨角鯨也被稱為海洋中的獨角獸，因為它們最令人印象深刻的資產就是它們的獠牙。這些獠牙實際上是一種犬齒，從上頜左側伸出，穿過嘴脣，形成左旋螺旋狀。有些雄性（大約五百分之一）實際上有兩顆獠牙。科學家們仍在爭論和尋找象牙的生物功能。雖然答案仍是未知的，但主要的理論認為它在某種程度上參與了交配或繁殖的展示，因為事實上雄性往往比雌性更經常長出象牙。然而，最近的分析表明，長牙是一個高度神經支配的感覺器官，有數百萬個神經末梢。是以，這種長牙似乎是某種第六感，可以幫助動物
