Night Snakes

About 1 to 2 ruler lengths in size, cryptic, and nocturnal, the Night Snake is perhaps the least understood snake in British Columbia.  The superficial resemblance of Night Snakes to juvenileRattlesnakes and Gopher Snakes may contribute to their mystery…and perhaps their rarity.   Similar to other blotchy snakes found in the same hot regions, Night Snakes are tan, grey, light brown or pinkish grey with dark brown squarish blotches running down the back.  A smaller series of blotches often marks each side of the body.  And like Rattlesnakes, Night Snakes have vertical pupils. 

However, Night Snakes have 4 key features that distinguish them from Rattlesnakes.  Most obvious is the lack of a rattle (and potentially harmful venom)!  Night Snakes are not truly venomous; the venom they produce is just strong enough for their small prey.  Night Snakes also have smaller markings, a less distinct neck, and smooth scutes (scales).   In comparison, the scales of Rattlesnakes are keeled (a ridge runs down the middle of each scale).  Finally, Night Snakes have a dark band across each eye and a dark collar-like marking around the neck that often runs into the eye bands, a combination of markings unique amongst B.C.’s snakes.
