Stentor is a genus of trumpet-shaped ciliates found primarily in stagnant fresh water. There are 22 known species of Stentor but there are most likely more that have yet to be discovered. Reaching a length of up to two millimeters, Stentor are amongst the largest known unicellular microorganisms.

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). With many myonemes, it can contract into a ball.

A microscope is required in order to see details of the Stentor’s structure and behavior. If a microscope is available, watching a living Stentor can be a very absorbing activity. Examine the dish with a low magnification lens – any Stentor present …

2023年3月6日 · Stentor can be easily identified under a microscope with the help of its unique characteristics. Its large size, large peristome and trumpet-shaped lorica make it easy to distinguish from other single-celled organisms.

Stentor are one of the largest protozoa found in water, and is therefore one of the easiest for the microscopist to study. This article describes where you can find the Stentor and how different types of illumination under the microscope can be used …

Stentors are a unicellular ciliate, noted for their trumpet like shape (hence the name stentor, after the Greek herald of the Trojan war). Stentors are one of the largest single celled organisms, occasionally being several millimeters in length.

The fine structure of the ciliate Stentor has been studied by means of the electron microscope and the results have been correlated with observations made on the living organism by means of light microscopy; special reference has been made to structural features which may be responsible for contraction and extension in Stentor. Descriptions ...

2021年10月9日 · Exploring the massive world of microscopic creatures, with a keen focus on the stentor - some of the largest unicellular organisms in the planet.

2015年11月13日 · Stentor protozoa (Stentor polymorphus) are single-celled animals that grow to a length of 1.5 to 2 millimeters, much larger than many of their fellow multi-cellular aquatic organisms. Often, stentors will attach the lower portion of their pod to debris and assume the trumpet shape illustrated above.

Stentor are sometimes referred to as trumpet animalcules because of their horn shape. They typically reach a full grown length of 2mm and are among the largest known unicellular organisms.
