ACTINOPODS
From the Phylum Actinopoda

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

WHAT DO THEY EAT?
Unicellular algae

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

DO THEY PHOTOSYNTHESIZE?
Yes
Photosynthesize through algal endosymbionts

REPRODUCTION
By binary fission or budding

MOVEMENT
Some produce flagellated reproductive cells

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
