Reproduction and Development in Aschelminthes. -

  • Aschelminthes are dioecious animals, i.e., the male and female reproductive organs are present in different individuals. 
  • Sexual dimorphism is also observed, i.e., females are longer than the males. 
  • Fertilization is internal and development occurs through the larval stage. 
  • Hence, the development is indirect.

The following types of larvae are seen in different roundworms:

  • Filariform larva - hookworm
  • Microfilaria larva - Wuchereria
  • Rhabditiform larva - Ascaris
