Amoeba
Paramecium
Blepharisma
The Blepharisma is a common ciliate found in
most any pond. It is similar in size and shape to
the Paramecium, but displays an unusual
characteristic, albeit a potentially fatal one. It is
easily spotted because, unlike most of its
community pond inhabitants, it is not
transparent, but rather a striking pink color
under normal conditions. When exposed to an
intense artificial light, such as that from a
micro-projector, the pink pigment emits a
poisonous toxin that completely disintegrates
the creature.

Euglena
Stentor
The green color tone in this pair is
probably due to the presence of
symbiotic green algae

Vorticella
Chilomonas
Chilomonas are very common and are one of the chief
food sources for larger protozoans, especially Amoeba
proteus.

Didinium
The Didinium is a protozoa that feeds exclusively on Paramecia. If a culture of Paramecia is innoculated with
just two Didinium, the Didinium will wipe out the colony of Paramecia in just a few days, regardless of how
large the culture is. It takes about one minute for the Didinium to consume a Paramecium, after which it
moves on to consume another - sort of non-stop gluttony. The more they eat, the bigger they get, and the
bigger they get the sooner they split into more of themselves. The Paramecia don't have a chance.

Volvox
Spirostomum
…Can grow to to a size of more than 4 millimetres. It can therefore be seen without the help of
a microscope. When observed swimming in a little jar of pond water it looks like a little worm.
The organism can contract it's body to 1/4 of it's length in 6-8 millisec which is the fastest
contraction known in any living cell. …Feeds on bacteria. Like many large single celled
organisms (giant amoebas, or Stentor: the trumpet animalcule) it has not one nucleus but many.
The nucleii form a long strand, like a string of pearls.
