I generally do not like posting species if I have a poor phone picture but for this I will make an exception. Just today I found two Iberian Sharp Ribbed Newts who have a specialized defense. The orange dots running along the side of the individual are the sections where the newt will push out its sharp bony ribs to stab a predator. They can move their ribs and poke them through their skin, which have a poisonous toxin in order to defend themselves. Afterward they retract and their skin heals quickly. I'm honored to have found such a cool species!
The Iberian ribbed newt or Spanish ribbed newt is a newt endemic to the central and southern Iberian Peninsula and Morocco. It is known for its sharp ribs which can puncture through its sides, and as such is also called the sharp-ribbed newt.
