Subgroup amoebazoa

1. Protozoan Taxonomy
Animal Diversity-I

2. Supergroup Amoebozoa
 Members of the Amoebozoa are the
amoebae (sing., amoeba). When
feeding and moving, they form
temporary cell extensions called
pseudopodia .
 Pseudopodia are false foots.
 Pseudopodia exist in a variety of
forms.

3. Lobopodia
 Lobopodia are broad cell processes
containing ectoplasm and endoplasm
and are used for locomotion and
engulfing food.

5. Filopodia
 Filopodia contain ectoplasm only and
provide a constant two way streaming
that delivers food in a conveyor-belt
fashion.

6. Reticulopodia
 Reticulopodia are similar to filopodia,
except that they branch and rejoin to
form a netlike series of cell extensions

7. Axopodia
 Axopodia are thin, filamentous, and
supported by a central axis of
microtubules. The cytoplasm covering
the central axis is adhesive and
movable. Food caught on axopodia
can be delivered to the central
cytoplasm of the amoeba.

9.  Some members in this supergroup
lack a test, cell wall, or other
supporting structures. These amoebae
are naked and are normally found on
shallow-water substrates of freshwater
ponds, lakes, and slow-moving
streams, where they feed on other
protists and bacteria.
 They engulf food by phagocytosis.

10.  Binary fission occurs when an amoeba
reaches a certain size limit. As with
other amoebae, no sexual
reproduction is known to occur.
