Pristurus carteri, commonly known as Carter’s rock gecko or Carter’s semaphore gecko, is a species of gecko, a lizard in the family Sphaerodactylidae. The species is endemic to the Sinai Peninsula.
P. carteri may attain an average snout-to-vent length (SVL) of 5–6 cm (2.0–2.4 in), and a total length (including tail) of 8–9 cm (3.1–3.5 in).
P. carteri are often seen swaying their curly tails back and forth to each other in a way to sort of communicate to each other. The males develop little fleshy spikes on their tails upon reaching sexual maturity. When they feel threatened they curl their tails in a scorpion-like fashion and even mimic the movements a scorpion will use as a threat display; this and the tail waving are the source of the common name scorpion-tailed geckos.
