Reproduction and Development in Porifera -

Sponges reproduce both asexually and sexually. The asexual reproduction occurs through the following:

  • Buds
  • Gemmules
  • fragmentation
  • Sponges are hermaphroditic. 
  • Ovum and sperm are formed within the same individual. 
  • Development involves free-swimming larval stage, hence the development is indirect.
  • Parenchymula larva is seen in Leucosolenia and Clathrina while Amphiblastula is seen in Sycon.
