Crusty, cause he likes some worms and lizards better than humans?

 

regeneration


 

 
 

The growth of new tissue or organs to replace those lost or damaged through injury. All animals and plants are capable of regeneration to some extent but, as a general rule, the more highly evolved an animal is, the less are its powers of regeneration. Humans, for example, are able to regenerate skin and bone tissue to mend wounds and fractures, but are unable to regrow even a finger if one should be lost. Some internal organs can be regenerated if a large enough part remains as a starting point. The liver is an example; so, too, are the adrenal glands. The replacement of worn-out tissues is a form of regeneration and goes on throughout life. The most obvious is the replacement of skin from below as the outer layers rub off.

Some animals are able to regenerate new limbs – in fact lizards may actually shed their tails themselves to confuse enemies and later grow knew ones. Crabs, too, can throw off a limb to escape from an enemy. The most striking cases of regeneration, however, are found among the lower animals – the cnidarians and the flatworms.
