Stentor coeruleus is a

Stentoridae which is characterized by being a very large ciliate
that measures 0.5 to 2 millimetres when fully extended.

The pronunciation of S. coeruleus is counterintuitive because the "oe" is actually the Latin character œ and is pronounced as if it were just an E.

S. 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. It has the ability to contract into a ball through the contraction of its many myonemes .[2]

Stentor coeruleus is known for its regenerative abilities.[3] When this organism is cut in half, each half is able to regenerate a cell that has its normal anatomy provided that each cut part includes some of the macro-nucleus.[4] It feeds by means of

cilia
that carry food into the gullet.

DNA

The

introns are unusually small, only 15 or 16 nucleotides long.[5]

Reproduction

S. coeruleus is capable of

binary fission.[6]
