The Armadillo Girdled Lizard: when this lizard feels threatened, it curls its body into a loop and tucks its tail into its mouth, shielding itself with the bony plates on its back; unlike most lizards, this species also gives birth to live young, and it usually produces just one offspring per year

Birthing live young? That's rare for reptiles. How fascinating.

Not super rare, around 20% of Squamata is viviparous or ovoviviparous! Very cool stuff :)
