What is it in a sea-star (or starfish for those who don't know
the difference) that allows them to regrow an arm and the central disc
isn't what I'm looking for what is it in there genes or cells that allow
them to do this?
Presumably there are omnipotent stem cells in various parts of the sea star
which can divide and differentiate into the various cell types necessary to
regenerate a whole organism.
