Abstract

Regeneration in arthropods and amphibians follows an analogous principle making comparisons between the two phyla possible.Larval arthropods and amphibians possess powers of epimorphic regeneration which wane for many species of these phyla with the completion of metamorphosis or the cessation of moulting. In those species which retain, post-maturationally, the ability to form a regenerative blastema, larval characteristics are carried into the adult and reproductive stages of these organisms. These include many species of: urodeles, ametabolous insects, crustaceans, myriapods and arachnids. The long-standing distinction between embryonic regulation and true epimorphosis would thus appear to be a difference of degree rather than kind.
