The Baja California coachwhip (Masticophis fuliginosus), also known simply as the Baja coachwhip, is a species of non-venomous snake found in Mexico and the United States. A large and fast moving snake species, the Baja California coachwhip typically reaches lengths between 2-4.3 ft (24-52 in). This species comes in a few color morphs, some of which are region-specific. Throughout their entire range, individuals can have a sleek all-black coloration. Or they can be a dull yellow, with a black or brown head and neck area. In the more southern portions of their range, they may be light grayish-white with a black or brown head and neck. In all morphs, the underbellies are light yellow to white. In California, the black and the yellow morphs are observed. Along the Baja peninsula, any of morphs can be observed. All the morphs throughout their range may have various levels of mottling. The body plan is very similar to a closely related species, the coachwhip (Masticophis flagellum). They share large forward facing eyes (which allows great vision and depth perception), slender proportions, and a long tapering tail. Both have large scales above the eyes and a braided appearance...

GBIF citizen-science records
It is estimated from how often the Baja California Coachwhip is recorded against all the reptiles logged in Cabo Pulmo National Park (5 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.
