Some animals regenerate, some form scar tissue. It's thought that scar tissue is a cheaper and faster mechanism than regrowing limbs and has thus been selected in many cases.
- 8n4vidtmkvmk 2y agoIf an iguana loses its tail, it doesn't just bleed until the new tail starts forming, right? Doesn't it seal up and then regrow?
