### **The Bouton’s Snake-eyed Skink (*Cryptoblepharus boutonii*)**
Identification
This diminutive, streamlined lizard is a master of the shoreline. Reaching roughly 10–12 cm in total length, its body is elegantly flattened—a specialized adaptation for squeezing into razor-thin rock fissures. Look for a glossy, coppery-brown dorsum flanked by two vibrant, pale-cream longitudinal stripes running from the snout to the base of the tail. Its most striking field mark is the "snake-eye": unlike most lizards, this skink lacks moveable eyelids. Instead, it possesses a transparent, permanent scale (a spectacle) over the eye, giving it a fixed, unblinking gaze that is unmistakable under a hand lens.
Habitat & Range
A true "littoral specialist," this species is primarily endemic to the volcanic coastlines of Mauritius and its offshore islets. You won’t find it in the lush interior forests; instead, look for it in the harsh, salt-sprayed intertidal zones. It thrives on dark basaltic rocks and weathered coral rubble, often living just centimeters away from the crashing Indian Ocean surf.
Behaviour
Watching a Bouton’s Skink is a lesson in high-speed agility. They are strictly diurnal, emerging as the sun hits the coast to bask on dark, heat-absorbent rocks. They are incredibly wary; at the slightest shadow of a bird or hiker, they vanish into crevices with liquid speed. While they are generally solitary foragers, you may see them in high densities where basking spots are prime, performing subtle head-bobs to signal territory to neighbors.
Diet
These skinks are the clean-up crew of the "splash zone." They dart across sun-baked rocks to snatch up beach flies, tiny isopods, and amphipods. Their hunting style is frantic and precise, utilizing their keen, unblinking eyesight to spot the minute vibrations of prey against the dark stone.
Fascinating Fact
The Bouton’s Snake-eyed Skink is one of the few lizards that isn't afraid to get its feet wet! To escape terrestrial predators, it will fearlessly leap into saltwater tide pools, where it can actually "skate" across the surface tension or submerge completely to hide until the danger passes—a remarkable feat for a non-marine reptile.
