A few more microbes

Scientific name: Stentor coeruleus
Class: Heterotrichea
Phylum: Ciliophoria

 

Stentor coeruleus is a protist in the family Stentoridae which is characterized by being a very large ciliate that measures 0.5 to 2 millimetres when fully extended.

Stentor coeruleus specifically appears as a very large trumpet. It contains a macronucleus that looks like a string of beads that are contained within a ciliate that is blue to blue-green in color. Being that it has many myonemes, it has the ability to contract into a ball. It has the ability to swim while both fully extended or contracted.

 

Stentor coeruleus is known for its regenerative abilities. When this organism is cut in half, each half is able to regenerate a half-sized cell that has its normal anatomy and will look the same way it did prior to being cut.

Eating is accomplished using cilia that carry food into the ciliate's gullet.

Scientific name: Campanella umbellaria
Class: Oligohymenophorea
Phylum: Ciliophoria

 

The stalks on Campanella umbellaria do not contract instead the body is contractile. We can also see dark cytoplasm and a very thick peristomial lip this is caused by multiple windings of peristomial cilia, which are also visible here as dark lines on the lip.

A mixture of detritus and bacteria mainly, you do see the occasional little microbe go by.
