Whose work first showed that sea stars can regenerate lost arms?
Quick Answer
Regeneration in sea stars was documented by naturalists and later experimental biologists over the 19th and 20th centuries. Some species can regrow arms, and in certain cases parts of the body can regenerate extensively.
The Full Story
Sea star regeneration has fascinated biologists for more than a century. Early naturalists noticed that these animals could recover from injury, and later experiments clarified the process in detail. Some species can regenerate lost arms, and in a few cases a detached arm with part of the central disc can regrow into a whole animal. This ability makes sea stars important models for regeneration research.
