The
Difflugia is a small amoeba and belongs to the Phyllum
Sarcodina. It
lives in a rather large chitinous "test"
(shell). The shell is usually covered completely with sand grains.
The Difflugia is from 200-250 microns long. Pseudopods extend out from the
shell and are used for locomotion. This
shelled rhizopod feeds mainly on Spirogyria (a green algae) These
amoebas are available from science supply companies and the shell
architecture and feeding habits make the Difflugia interesting to
observe. |
