Paramecium are oval in shape with pointed ends. They are known as
slipper animalcules because of their slipper like shape. The
pellicle is stiff and elastic allowing for it to keep its shape.
Covering the pellicle are many tiny hairs known as cilia. They
are 50 ro 350 micrometers in length depending on which species it
is. They are single celled protazoa organisms.
Habitat: Paramecium can
be found in freshwater. They are also attracted to acidic
Range: They can be found all
over the world.
Description: The cilia on
this organism allow the creature to move. The hairs beat down on
an angle backwards which pushes the paramecium foreward. To go
backward, the cilia beat down at a foreward angle. So,
paaramecium simply spiral through the water on an invisible axis in
order to move. When it runs into something, it will use the cilia
to back up and change direction. Cilia also allow for the
paramecium to eat. Hairs sweep food into its "mouth" after it
reaches the oral groove. The food goes into the cell mouth and
when enough food has accumulated it creates a vacuole. It then
travels through the body and waste is excreted. Paramecium feed
on things like bacteria, algea, and yeasts.
