9-10岁口腔磨损严重的老狼(V079)近照

只看楼主收藏回复

【预警 图片可能有点血腥其实没血,但就是磨损太严重了看着有点。。
机翻
我们周六重新捉到的狼V079是一个很好的例子,说明了狼年老时牙齿的变化。狼V079是一只9-10岁的狼,是月影族的雄性繁殖者。
从下面的照片中你可以看到,V079少了几颗牙齿,他的犬齿都磨碎了(一只犬齿完全脱落),门牙也磨坏了。
他口腔后部的大臼齿(他的大臼齿)磨损相当严重,但实际上比他其他牙齿的形状更好。
狼的牙齿很坚韧,因为它们的牙齿/嘴巴是它们捕猎猎物的主要工具,也因为狼会咬碎猎物的大骨头。咬碎骨头会导致牙齿磨损,而用嘴咬猎物则会导致牙齿断裂或全部脱落。
真正活到老年的狼最终会饿死,部分原因是它们没有牙齿来捕捉和吃掉猎物。也就是说,像Wolf V079这样牙齿状况不佳的狼居然能杀死猎物,这有点令人震惊。

      原文
      Wolf V079, who we re-collared on Saturday, is a good example of what happens to a wolf’s teeth when they reach old age. Wolf V079 is a ~9-10 year old wolf who is the breeding male of the Moonshadow Pack.
      As you can see in the photos below, V079 is missing several teeth, his canines are worn down to nubs (one canine was broken off entirely), and his incisors are worn down as well.
      His large carnassial teeth (his big molars) in the back of his mouth are considerably worn but are actually in better shape than the rest of his teeth.
      Wolves are tough on their teeth because their teeth/mouths are their primary tool to take prey down and because wolves crunch on large bones from kills. Crunching on bones causes tooth wear whereas trying to take down prey with their mouth can lead to broken teeth or losing teeth all together.
      Wolves that truly reach old old age will eventually starve to death, in part, because they don’t have any teeth to catch and consume prey with. That said, it is kind of astounding that wolves like Wolf V079 who are in poor ‘dental” condition are able to kill prey at all.
