Regeneration in L. variegatus follows a set pattern which was studied by the Russian embryologist Piotr Ivanov. If the regenerating segment originated less than eight segments from the anterior tip, this number of segments are regenerated; if, however, the segment was originally from a more posterior position, only eight segments are regenerated.
His research was on the regeneration of segments in the worm Lumbriculus variegatus for which he received a gold medal in 1901. He then went to the biological research station, Naples to study regeneration in marine annelids.
Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage. [1] Every species is capable of regeneration, from bacteria to humans.

Epimorphosis is defined as the regeneration of a specific part of an organism in a way that involves extensive cell proliferation of somatic stem cells, [1] dedifferentiation, and reformation, [2] as well as blastema formation. [3]
The Lumbriculidae are a family of microdrile oligochaetes common in freshwater environments, including streams, lakes, marshes, wells and groundwater. They should not be confused with the earthworm family Lumbricidae.
In ecology regeneration is the ability of an ecosystem – specifically, the environment and its living population – to renew and recover from damage. It is a kind of biological regeneration . Regeneration refers to ecosystems replenishing what is being eaten, disturbed, or harvested.
