1. ACtinopods From the Phylum Actinopoda

2. Basic description • Unicellular protists • Mostly marine plankton organisms • Have axopods that protrude through pores in their shells • Axopods are strengthened by a cluster or microtubules

4. What do they eat? • Unicellular algae

5. How do they Eat? • Actinopods use axopods to trap prey • Prey becomes entangled in axopods & is later engulfed outside the main body • Cytoplasmic streaming carries prey back within the shell

6. Do they photosynthesize? • Yes • Photosynthesize through algal endosymbionts

7. reproduction • By binary fission or budding

8. Movement • Some produce flagellated reproductive cells

9. Radiolarians • Classified as an Actinopod • Some Actinopods secrete shells made of silica, which are known as radiolarians • Radiolarians are usually not visible to a light microsope

10. The end!
