Rhinocheilus Lecontei – Long-Nosed Snake

Rhinocheilus Lecontei - Long-Nosed Snake information

The long-nosed snake is a nonvenomous snake found in arid habitats in the Western United States. It has alternating black and red color patterns (crossbands or rectangles) on a white or cream-colored background.


The body of the long-nosed snake is characeristically colored with red, black and cream-colors. The snake has several alternating red and black rectangular shapes. In some specimen, the alternating colors can look more like crossbands or rings. The red colors are usually white or cream-colored scales with a red spot in the center. The belly of the snake is yellow, cream-colored or white and black.

As its common name suggests, the long-nosed snake is characterized by an elongated “nose”. Even though it doesn’t have a nose, its snout is long and slightly upturned and the mouth is retracted. The eyes are red or orange with black and round pupils.

Adult long-nosed snakes reach an average length of 20-30 inches (50-75 cm).

Hunting behavior and habitat

Long-nosed snakes are nocturnal and terrestrial reptiles that feed on small lizards and amphibians and occasionally on rodents. Their habitat consists of scrubland, hot desert areas and drier parts of savannas. They live under rocks, wood stumps and in burrows of rodents.


The long-nosed snake is a relatively small and nonvenomous snake. Even when handled by humans or larger pets, the snake does not have the instinct to bite. As many other small and nonvenomous snakes, the long-nosed snake will release a foul-smelling musk from its cloaca when it feels threatened. The intense small should deter predators. Even in the unlikely case that the snake bites through human skin, it will not have any significant medical effects.
