  1. Phylum Ctenophora By: Hend and Ziyad Bio 1023

  2. Introduction: • Name and symmetry • Evolution and morphology • Digestive system and feeding • Movement • References

  3. Phylum Ctenophora • “Name from comb-like rows of cilia” - Cilium. - Cilia. • 100 species; all marine

  4. Evolution and Morphology. • Ctenophore live up in the water column. • Many solutions have evolved over the last 500 million years • Bell form : Interact with the fluid around them. • - Successfully movement. • - Capture food: determine feeding strategy, gut capacity and digestive times. • - Cvoid being eaten. • - Some bell shapes appear to limit the size that medusae can grow. .

  5. Digestive system mouth • Digestive system with mouth and anus. • Feeding by discharging colloblasts(glue cells) from long tentacles. anus

  6. Movement: Move by beating cilia on comb rows.

  7. Comb jellyfish Chemical light production in Comb jellyfish, it oxidized by luciferase to produce molecule that emits light.
