[1] A large and fast moving snake species, the Baja California coachwhip typically reaches lengths between 2-4.3 ft (24-52 in).

In the more southern portions of their range, they may be light grayish-white with a black or brown head and neck.

[5] 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.

These include coastal sand dunes, inland grassland, scrubland, riparian environments, and agricultural areas.

[9][10] In the uppermost region of their range around California, they co-exist and potentially intergrade with the coachwhip (Masticophis flagellum).

Unlike most snakes, Baja California coachwhips are primarily pursuit predators, chasing prey down.

However, their strong bite and ability to overlay coils on top of prey can help subdue via crushing and/or suffocation.

[18] Like most living reptiles, Baja California coachwhips are ectotherms and cannot regulate their body temperature on their own.

Thus, they bask on rocks, roads, open ground, or under surface cover in order to warm up.
