A reader writes, "I know that starfish have amazing powers of regeneration, but I have seen pictures of regenerated starfish and in some the regenerated arms are much smaller than the original arms.

In my stack of starfish letters, I also found a good question. For a research project, a student, Laura, chose starfish regeneration. Laura wrote that she knows a starfish can grow into a new individual from one torn-off or castoff arm, but she read that the new arms never grow as big as the original.

Hoping to discover whether the limb-regrowing powers of creatures like starfish and salamanders hold the secret to human renewal, University of Florida researchers are set to embark on a $6 million Regeneration Project.

Starfish are well known for their powers of regeneration. A complete new animal can grow from a small fragment such as a arm. In some species (Linckia multifora and Echinaster luzonicus) one of the arms will virtually pull itself away, regenerates and forms a new animal.

Starfish regeneration isn't quite like that of a liver cell or a blood cell, since the cells that replace the lost limb need to differentiate into many other types of cells. Liver and blood cells are already somewhat specialized, and are not as versatile as the starfish regenerative cells.

Regeneration is also used when a starfish loses an arm, which is a fairly common occurrence. Although helpful, the process of regeneration may take up to a year. (Blaxland, 12-13); Sexual reproduction is slightly more complicated. ... Starfish Regeneration (8/28/03) [ Researcher: Lindsey ]
