|TURBELLARIA||Free-living flat worms|
Flatworms have simple, flattened, leaf-like bodies and glide along on a bed of fine hairs or by ripples of contracting muscles.
A flexible tubular proboscis traps prey such as small crustaceans and molluscs. The digestive canal ends blindly without any anus.

Flatworms are hermafroditic, but cross fertilise. Partners then lay strings of large yolky eggs.
