就是这个关于single oviparity和multiple oviparity。
Nakaya (1975) distinguished between two types of oviparity in sharks: single oviparity and multiple oviparity
我看到的文献里说的是，这两种的区别在于输卵管中卵的数量多少？是这个意思吗？？英语废柴实在不太懂。
Single oviparity occurs when a single egg case is formed in each oviduct and deposited before the embryo develops, resulting in an extended hatching time ranging from several months to a year. Multiple oviparity occurs when several egg cases are formed in the oviduct over a period of time and the embryos develop to varying degrees before deposition, resulting in a relatively short hatching time (Compagno, 1988)
希望各位大神能解释下哈！
多谢~
