This study details a protocol for isolating sponge embryos, larvae, and juveniles. These developmental stages are crucial for various molecular and cellular analyses in Amphimedon research.

Area of Science:

  • Marine Biology
  • Developmental Biology
  • Invertebrate Zoology

Background:

  • Amphimedon sponges exhibit internal fertilization and brood embryos internally.
  • Each brood chamber contains a mix of developmental stages, from early embryos to late-stage pre-hatch embryos.
  • Embryogenesis culminates in the release of swimming parenchymella larvae.

Purpose of the Study:

  • To provide a detailed protocol for obtaining Amphimedon embryos, larvae, and post-larvae/juveniles.
  • To facilitate molecular and cellular analyses of distinct developmental stages in sponges.
  • To support research into sponge development and life cycles.

Main Methods:

  • Isolation of embryos from adult Amphimedon sponges.
  • Collection of swimming parenchymella larvae post-emergence.
