The body cavity is reduced in leeches, and the bristles are devoid of some specialized morphology, including leeches. An important phylum of invertebrates in the animal kingdom, Annelida, consists of more than 9,000 species divided into three classes: Sea worms (polychaetes) are divided into motile and sedentary or tube-dwelling forms. earthworms (Oligochaeta); and leeches (Hildinea). Annelids are coelomic and tridermal.

General characteristics of annelids are:

  1. They show organization at the organ system level.
  2. Your body is segmented.
  3. They breathe through their body surfaces.
  4. The kidney is an excretory organ. They have well-developed circulatory and digestive systems.
  5. Common names for more familiar annelids include earthworms, sandworms, annelids, bristleworms, and leeches.
