Young animals and species low in the evolutionary scale usually have greater regenerative power than the older or higher animals. If cut into pieces, each one can become a new sea cucumber. This type of regeneration is a regular physiological function including the continuous replacements of cells and tissues, and thus is indispensible for the maintenance of life in all animals. I identify some animals, such as planarians (flatworms), which can the existence of regeneration-specific processes, i.e., pro- regenerate their entire body from small tissue fragments, or cesses that occur during the regeneration, but not the initial Hydra, which is able to completely regenerate its head after development, of a given structure. 2.
