这个问题的答案是：是的，啮齿动物有骨头。 正如我们已经看到的，老鼠是哺乳动物，就像猫和狗一样，例如，这些动物因为一些类似的特征而被划分。
这意味着它们与上述动物，甚至与人类没有多大区别。 因此，大鼠有一个骨架：头部、躯干和四肢。
大鼠的特征
大鼠是一种有骨头的哺乳动物，它的生物分类保证了它的特点，如：由内部骨骼支撑，即内骨骼，它分为三个部分。 看看它们是什么。
第一部分是头部，薄而细长。 第二部分是躯干，有24至26个极其灵活的脊椎骨，这就是为什么它们可以进入狭小的地方。 第三部分是它们的腿，前面的腿比后面的腿小，用于支撑。
这就是为什么老鼠的用途很广，适应性很强，这也是很多人认为老鼠是无骨的原因。
老鼠是一种哺乳动物，但更多的好奇心呢？
现在你知道了老鼠是哺乳动物，而且有骨头，那么一些奇闻异事呢？
正是由于它们的一些特点，它们是如此灵活的动物。 据BBC报道，它们可以挤进小到1厘米的空间。
另一个令人好奇的现象是，通过它们的胡须，它们对地方的尺寸有一个概念，也就是说，啮齿动物利用这个部分来移动，知道它们在所在空间内的极限，或者它们打算去的地方。
除此以外，它们是极其欢快和精力充沛的动物，所以如果你家里有一只老鼠，尽量把玩具留给它，让它娱乐。
如何玩转小鼠
除了野生小鼠，还有几个物种是人类的完美伴侣：仓鼠、沙鼠、扭扭鼠等。 而饲养它们远不止是把它们放在笼子里。 就像其他动物朋友一样，它们需要关注。
