Pacific gopher snake
Pituophis catenifer catenifer is a subspecies of large non-venomous colubrid snake native to the western coast of North America. Pacific gopher snakes are one of California's most common snake species. They often get confused for rattlesnakes because they mimic similar patterns and defense mechanisms. As a result, gopher snakes can often avoid confrontation without needing to rely on their non-venomous nature for survival.
Pacific gopher snake adults range in size from 3–7 ft (0.91–2.13 m) in total length. However, most of the subspecies reach a length of 4–5 ft (1.2–1.5 m). The hatchlings are relatively long, and they have been recorded at lengths upward of 20 in (510 mm).
The Pacific gopher snake has a base color ranging from yellow to dark brown and has a gray coloring on the sides of the body. It is a spotted snake, with the spots being dark brown. Usually there are 41 to 99 spots on the body, while the tail spots range from 14 to 33. The side of the body has 2 or 3 rows of alternating black and brown spots.
A snake with keeled scales, and a narrow head that is wider than the neck, the Pacific gopher snake also displays a protruding rostral scale on the tip of the snout. The two most common base colors are straw and straw gray, though the species' color varies widely. The dorsal blotches, or saddles, are well-defined and generally dark to chocolate brown, though some specimens have had black blotches. The side blotches are often brown or gray. The back of the neck is dark brown. In many areas, such as Solano County, California, the snake can be found in a striped morph.
The ventral side may be cream-colored to yellowish with dark spots. On the dorsal side, especially near the tail, there is often a reddish coloration.
As aforementioned, there are two to three rows of spots on the side of the Pacific gopher snake. However, the San Diego gopher snake (P. c. annectens) has 3 to 4rows of smaller spots on its side. The Pacific gopher snake's saddle spots do not have the barren characteristic as those of the San Diego gopher snakes do. Also, the spots in the second row of spots are much larger on P. c. catenifer as compared to P. c. annectens. Finally, the Pacific gopher snake generally has more saddle spots than the San Diego gopher snake.
The diet of pacific gopher snakes mainly consists of small rodents. They also consume birds, bird eggs, lizards, and occasionally insects or bats, depending on what is available in its habitat. The Pacific gopher snake is diurnal, hunting for prey during the day, however, it is sometimes seen out hunting in night time. It may also exhibit nocturnal behavior in warmer conditions. To hunt, they will enter underground burrows, perch on sites during the day, or strike unsuspecting prey resting at night, ultimately using constriction to immobilize and kill their prey. Its preference for agricultural fields and open spaces makes it an important natural pest controller in its ecosystem, helping manage rodent populations.
Like other gopher snakes, the Pacific gopher snake can produce a loud hiss when agitated or fearful. When threatened, this species will inflate its body, flatten its head, and vigorously shake its tail, which may produce a rattling sound if done in dry vegetation. However, gopher snakes are non venomous, generally good natured, and not harmful to humans.
