Flatworms, with their 3 clearly defined cell layers and bilateral symmetry, represent an important advance in early animal evolution. This program provides detailed observations on structure, behaviour and their life cycles.
Phylum Annelida is made up of segmented worms divided into 3 classes: Subclass Oligochaetes such as Tubifex, Class Polychaetes such as Nereis and thousands of other species that live in almost all marine habitats & Leeches.
This DVD updates the five kingdoms classification with the latest understanding of life’s organization based on DNA, fossil, and biochemical evidence, reorganizing all life into 3 great branches: Archaea, Bacteria & Eucarya.
This DVD presents a series of field trips in aquatic micro-space where students learn to recognise the common forms of micro-life, and explore their ecological relationships.
