Study Notes
Platyhelminthes Overview
- The term 'platy' refers to the flat shape of these organisms, derived from the Greek word meaning "flat."
- Commonly known as flatworms, Platyhelminthes exhibit a simple body structure with bilateral symmetry.
Classifications and Types
- Platyhelminthes are classified into four main groups: Turbellaria, Cestoda, Trematoda, and Monogenea.
- This classification reflects their evolutionary relationships and anatomical features.
Body Structure and Habitat
- Flatworms possess a digestive cavity, which is not a complete system; it typically consists of a mouth but lacks an anus.
- The primary limitation on the shape of flatworms is the need for diffusion of gases and nutrients across their body surface, necessitating a flat form.
- Free-living flatworms primarily inhabit aquatic environments, thriving in both freshwater and marine settings.
Feeding and Digestion
- Flatworms do not process food continuously due to their simple gastrointestinal structure, which leads to intermittent feeding.
