Presentation Transcript


Phylum Porifera

  • Kingdom Animalia

  • Multicellular

  • Eukaryotic, No cell walls

  • Heterotrophic


Porifera – “Pore Body” has many pores

  • Around 5,000 different species

  • Most are Marine

  • No Symmetry, “Asymmetrical”

  • Range in size from 2 cm – 2 meters


Phylum Porifera

Freshwater Sponges


Phylum Porifera

Marine Sponges


Simplest Animal – Multicellular, No Tissues or Organs


Phylum Porifera


Ancestor of Animals

A colony of single celled Protists called…. “Choanoflagellates”


Asexual Reproduction- budding


Asexual Reproduction – Gemmules

Archaeocytes = Amoebocyte

These cells are “totipotent” – they are able to develop into any of the other types of sponge cells


Asexual Reproduction – Regeneration


Sexual Reproduction

Free – Swimming, flagellated larva is called a “Planula”

Sponges are “hermaphrodites” (produce both sperm and egg)
