Defines annelids, such as blood-sucking leeches and earthworms, and describes their physical characteristics, life cycles, habitats, senses, food, and means of self-defence. Suggested level: primary, intermediate.
Describes the physical characteristics, habitat, and types of worms, including leeches, earthworms, and tapeworms.
The group of segmented, bristle-bearing, worms, termed Oligochaeta by zoologists, comprises what are popularly known as earthworms together with certain forms, inhabitants of ponds, lakes and rivers, which are not so well known as to have received a more distinctive name than merely 'worms.' Their next allies are apparently the leeches and-a little more remote-marine bristle-bearing worms termed Polychaeta; the three groups, together with perhaps a certain number of other forms belonging to smaller groups, constitute the Annelida which are a distinct and separate assemblage of invertebrate animals.
This book describes worms, including their habitat and the adaptations they make to survive in their environment.
