Life of the Freshwater Sponge
- Synopsis
- Sponges, previously classified as Parazoa, which demonstrate characteristics of unicellular organisms, are now shown to have some features of true metazoans. Uses time-lapse photography to show sponges’ water purifying function, how their cells aggregate in a multicellular form because dissociated sponge cells cannot survive individually, and how sponges can distinguish themselves from others. Shows examples from ‘Ephydatia fluviatilis’.
