Postcard from the Reef – Regeneration

You may know that a starfish can regenerate a lost limb. Seeing it in process? More extreme… A single limb regrowing the rest of the body? It is a bit surprising to see such a bold example of regeneration in process.

The limb may have been parted by injury. Another possibility here is reproduction. Some species reproduce by simply detaching an arm in a process called autotomy. The detached arm becomes a new individual. An impressive capability indeed.
