Autotomy and regeneration in lizards. At some time in its life this Wall Lizard (Podarcis muralis) was caught by its tail. To escape,the lizard detached a part of the tail,an ability called autotomy,or self amputation. The tail started to wriggle violently and this,hopefully,distracted the predator. Over a period of several weeks the tail may be regenerated - not with a bony skeleton but a single piece of cartilage. The new scales usually look different in colour and shape too. The regenerated tail is often shorter. Some species can regenerated several times | |
