Annelida Animalia Flora and Fauna
Annelida Animalia Flora and Fauna
The phylum Annelida are the segmented worms. The three main groups are the Polychaeta, such as the lugworms, some of which are free living but others living in tubes, the Oligochaeta such as the earthworm and the Hirudinea, which are the leeches. All have bodies supported by internal pressure, a hydrostatic skeleton, and are divided into segments.
