狼的牙齿更好 – 2 级
02-11-2023 07:00
红狼是美国特有的一种狼，在一项繁殖计划的推动下，它正在缓慢地卷土重来。
华盛顿州塔科马的Point Defiance动物园通过照顾它们的牙齿来帮助它们。牙齿断裂会使这些狼难以正常进食。目前大约有 270 头红狼，其中大部分生活在动物园里，只有 20 头生活在北卡罗来纳州东部的野外。动物园的兽医为红狼进行了牙齿检查和清洁。他们还做了 X 光检查，并拔掉了坏牙。
动物园里的狼寿命更长，因为它们定期接受健康检查。红狼曾经生活在美国的许多地方，但生存艰难。动物学家们正在努力保护并重新引进它们。

正在采取哪些措施帮助将红狼重新引入其自然栖息地？
