Biology of Annelids DVD

(in stock)


Worms with segmented bodies make up the phylum Annelida. This program explores the 3 classes of annelids: Polychaeta (feeding, locomotion, and larval stages); Oligochaeta (lifestyles, feeding adaptations, and anatomy of freshwater oligochaetes and earthworms); and Hirudinea (leeches, crayfish, and worms show adaptations for commensal, parasitic, and scavenger lifestyles). Molecular genetics evidence places annelids close to the molluscs on the tree of life. DVD includes an illustrated PDF teaching guide. Close-captioned. 15 minutes.
