因此，在大多数情况下，这些卵子在外部环境中已经受精。 然而，在其他情况下，受精可能发生在卵子产下后。
繁殖过程
这些动物的繁殖特点是将卵子留在外部环境中。 大多数时候，这个过程发生在卵子已经受精的时候。 在它们变成小狗之前，这个过程发生在雌性动物的身体之外。

蛇
远远超出蛇的范围，最基本的是要知道不是所有的蛇都是蛇。 然而，更重要的是要知道所有的蛇都是产卵动物的例子。

你知道蚂蚁会产卵吗？
蚁后负责产下数以千计的卵，这些卵将为新的雄蚁和下一个蚁后让路。
企鹅也从蛋中孵化出来
友好的企鹅也是产蛋的动物。 不同的是，雄企鹅负责孵化每个蛋，并负责孵化后每个雏鸟所需的照顾。
八爪鱼也是产蛋的动物
最能引起人们好奇的卵生动物之一是章鱼，因为它们通常在外部产下大约一百个卵。 然而，根据雌性的安全，它们可以在不同的地方被发现。 因此，根据它们的性质，在孵化后，它们需要自己喂养。
