Iberian Ribbed Newt
The Iberian ribbed newt can be found in the central and southern Iberian Peninsula and Morocco, and it is also able to force a sharp part of its body to retract when it feels like it is under threat. The newt pushes its ribs through its skin and then defends itself against the unsuspecting predator.
When the ribs are pushed through, the newly formed pores secrete a poison. The attacker will get a sharp stab and inject the substance into the puncture wound for a fatal blow. The newt then repairs its wounds without forming any scar tissue. The ends of the ribs can sometimes be seen protruding through its skin. No wonder why it is also known as the sharp-ribbed newt!
