Stentor coeruleus
(Pallas, 1766) Ehrenberg, 1831
Stentor coeruleus is a large single-celled ciliate famous for reorganizing and regenerating damaged cell structures. Its elaborate body plan is built within one cell rather than from animal tissues.

Structure and identification
An extended cell has a pronounced front-to-back organization and a broad oral region. A contracted cell looks very different; the photograph shows a contracted individual with ingested material.
Habitat and range
The cited studies concern cultured ciliates and controlled experiments. They do not establish a complete geographic distribution or natural lifespan.
Nutrition and metabolism
Food is taken into the cell rather than produced by green-plant photosynthesis. Its feeding apparatus is a specialized region of the same single cell.
Biological activity
Experiments document contraction in response to touch, light avoidance and food selection. These responses do not require a multicellular nervous system.
Reproduction and life cycle
Growth and cell division maintain the population. Regeneration after experimental injury is repair and reorganization, not an extra animal-like life stage.
Ecological role
Its interactions with microbial food illustrate the complexity of unicellular life.
Distinctive adaptations
After suitable experimental damage, remaining cell material can restore a proportioned form. This ability has made it valuable for studying how cells know where to build structures.
