Eutely

Eutely (cell constancy) is a condition of an individual, organ, or tissue, in which no cell division takes place after a certain time point. As a result, the individual, organ, or tissue has a constant number of cells although some cell death processes may take place.

Rotifers, tardigrades, and nematodes are known to be eutelic in general.
