1. TURBELARIA

• Digestion : scavenging for bits and decaying plant and animal matter; prey on smaller organisms like protozoa. Food ingested and digest in gastrovascular cavity through pharynx; absorb nutrient and diffuse to another cells

ASEXUAL REPRODUCTION IN PLANARIA

2. TREMATODA (FLUKES)

Digestion :

• The fluke feeds on cells, blood, and other fluids of the host organism (paracitic)

• covering by tegument

• Have sucker (anterior and ventral) and hooks adaptation for parasitic worms

Life Cycle :

Host : Human and snail; fish or frog
