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.

What are Stentors known for?
It is known for possessing the largest 'trumpet' out of all species. A macronucelus within the Stentor is organized in a string of beads that are blue or bluish-green in color. The Stentor has the ability to contract down into a ball. It can also swim while fully extended or in a ball shape.
What is a Stentor for kids?
Stentor is a genus of filter-feeding ciliates. They are usually horn-shaped, and reaching lengths of 2 millimeters, they are among the biggest known unicellular organisms. They are a type of protist ciliate in the heterotrich class. ... They can regenerate, and small fragments can grow into full organisms.
What do Stentors do for the environment?
Stentor Habitat
They are found in freshwater bodies, like lakes and ponds, and tend to avoid flowing water found in streams and rivers. If we think about their food preference, this makes sense. Stentor eat bacteria, and bacteria tend to be found around decomposing organic material, like dead leaves or animals.
What type of organisms do Stentors eat?
Stentor are omnivorous heterotrophs. Typically, they feed on bacteria or other protozoans. Because of their large size, they are also capable of eating some of the smallest multicelluar organisms, such as rotifers.
How does a Stentor obtain food?
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.
Is a Stentor a sessile?
When feeding, the cell is fixed in place (sessile), attached by a posterior "holdfast" organelle to a firm surface such as plant stem or submerged detritus. Attached specimens are trumpet-shaped, and very contractile. ... It is a colourless species, with no pigmentation in the cell cortex.
Is Stentor algae or protozoa?
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.
Are Stentors plant like?
The second group is the ciliates and includes all protozoans that move by means of cilia. Examples include the Paramecium, Stentor, Vorticella and Didinium. ... Many protists exhibit both plant-like and animal-like characteristics and it is difficult to classify them either as protozoans or algae.
Is Stentor phytoplankton or zooplankton?
In four of 13 lakes, Stentor was an important constituent of the plankton community and contributed significantly to the total zooplankton biomass.
How does a Stentor move?
They can move in coordinated, rhythmic waves that propel organisms through water. Cilia are hairlike structures that project from cells. ... Beating cilia propel Stentor as it twists and turns in search of food in freshwater streams and lakes. Most larger organisms don't move with cilia, as tiny Stentor does.
What role does a Stentor play in a pond microscopic ecosystem?
[In this image] Stentor is a huge ciliate that you can easily spot under the microscope. Stentors can live in a variety of freshwater habitats, including ponds, pools, and ditches. ... Stentors use these cilia to sweep food particles into their mouths. They also swim by waving the cilia that cover their body.
