| 中文摘要: |
| 薄背涡虫(Notoplana humilis)的产卵高峰期在春末夏初。胚胎发育为螺旋式卵裂、外包法形成原肠胚,以大卵裂球储存卵黄。14~16℃下约20d左右幼虫由卵膜中孵化,但不是典型的牟勒氏幼虫。幼虫经历一周左右的浮游生活和两周左右的底栖生活后,逐渐发育为涡虫幼体。 |
| 英文摘要: |
| Notoplana humilis actively spawns in spring and early summer. Embryo undergoes spiral cleavage, epibolic gastrulation and uses macromeres to deposit yolk. The larva which needs about 20 days to hatch at 14-16℃, however, is not a Müller's type. The larva is planktonic for 1 week, demersal for 2 weeks, and undergoes gradual metamorphosis to become a juvenile flatworm. |
