The Iberian Ribbed Newt has a special defense mechanism. When in danger, it juts its pointed ribs out so that they pierce its skin, making it appear hard to eat. Once the predator backs off, the skin regenerates.

Melanocytes are cells that provide pigment/coloration to our skin and hair in the upper layer of our skin. A mole (or nevus, if we’re getting fancy) is actually considered a “benign tumor” of those melanocytes. ‘Tumor’ just means an abnormal, excessive growth of cells (not cancer), so essentially, some of your melanocytes had some funky things happen with their DNA (damage, random mutation, etc.) that caused them to grow more in clusters as opposed to spreading out across your skin.

The reason why you’re told to check the size, borders, color, etc. of moles is that benign moles and potential melanomas can look very different.

Praying Mantises have never been an endangered species, and it has always been legal to kill them in the United States. The contrary claim was just an urban legend floating around since the 1950s.
