The orange-throated whiptail (Aspidoscelis hyperythrus) is a species of lizard in the family Teiidae. The species was previously placed in the genus Cnemidophorus. Three subspecies are recognized as being valid, including the nominotypical subspecies.
A. hyperythrus is native to southern California in the United States, and to the states of Baja California and Baja California Sur in Mexico. A. hyperythrus has five or six light-colored stripes down a black, brown, or grey dorsal side. The middle stripe may be forked at both ends. The species is whitish-yellow or cream on the venter, and has an orange throat (females and juveniles may lack this character). Its head is yellow-brown to olive-colored, and its tongue is forked and flicked continually. It has a snout-to-vent length of 5–7.2 centimetres (2.0–2.8 in).
Juveniles of this species have cobalt blue legs and tails. The entire ventral surface of males, including the tail, may be orange, although gravid females may also have some orange especially lining the lower jaw. The colors are most distinct in the breeding season. Males have larger femoral pores than females.

Possible
About 20% of wildlife watchers report a Race-runner sighting in El Vizcaíno Biosphere Reserve on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 20 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Race-runner in El Vizcaíno Biosphere Reserve on a given day, against under 5% in November to May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Race-runner sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Race-runner sightings, El Vizcaíno Biosphere Reserve ranks 3rd at about 20%. The best odds are in Cabo Pulmo National Park (Mexico, about 30%) and Bahía de Loreto National Park (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Race-runner is recorded against all the reptiles logged in El Vizcaíno Biosphere Reserve (9 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
