What does Stentor look like under a microscope?

Stentor is a very large ciliate measuring from 500-2000 microns long when extended. There are a variety of species of Stentor. Stentor coeruleus is a very large trumpet shaped, blue to blue-green ciliate with a macronucleus that looks like a string of beads (dark connected dots on the left).

What color is a Stentor?

Stentor usually inhabit freshwater environments. They ingest and form photosynthetic relationships with algae, causing them to have a blue or green color. Stentor coeruleus exhibits a behavior called photodispersal. These organisms swim away from light and prefer to inhabit dim areas.

What is the classification of Stentor?

StentorStentor / Scientific name

Why would a ciliate be green?

They are green because they make use of a symbiotic green algae called Chlorella. The page about Green algae will show these algae in Close up. Ciliates usually multiply asexually by fission.

What is Stentor made of?

Stentor, genus of trumpet-shaped, contractile, uniformly ciliated protozoans of the order Heterotrichida. They are found in fresh water, either free-swimming or attached to submerged vegetation. Stentor assumes an oval or pear shape while swimming.

Where can I get a Stentor?

Stentors are commonly found in most freshwater ponds, attached to vegetation or other surfaces where they generally spend their lives. When necessary, they can detach and use their cilia to move to another location. While swimming, they assume an oval or pear shape.

What is the definition of Stentor?

Definition of stentor 1 : a person having a loud voice. 2 : any of a widely distributed genus (Stentor) of ciliate protozoans having a trumpet-shaped body with the mouth at the broad end and with the narrow end often attached to the substrate.

Where is Stentor found?

freshwater ponds
Stentors are commonly found in most freshwater ponds, attached to vegetation or other surfaces where they generally spend their lives. When necessary, they can detach and use their cilia to move to another location. While swimming, they assume an oval or pear shape. Stentors have remarkable regenerative powers.

How do Stentors move?

Stentor movement occurs as the cilia beat together, propelling the Stentor through the water. How do Stentor eat? Cilia around the Stentor push bacterial food particles over the mouth area so the Stentor can eat. The hair-like structures called cilia help the Stentor move and eat.

How do Stentors eat?

Stentors, like most ciliates, are filter feeders; passively eating whatever happens to be swept in their direction. They normally eat bacteria and algae, though large stentors are reported to opportunistically eat rotifers or anything else that they can catch.
