Loxocemus bicolor, the sole member of the monotypic family Loxocemidae and commonly known as the Mexican python, Mexican burrowing python and Mexican burrowing snake, is a species of python-like snake found in Mexico and Central America. No subspecies are currently recognized. Analyses of DNA show that Loxocemus is most closely related to the true pythons and the sunbeam snakes.
Adults can grow to a maximum of 1.57 m (62 in) in length, with most individuals averaging a length of 1 to 1.3 m (3.3 to 4.3 ft). The body is stout and very muscular. The snout is shovel-shaped, with a narrow head and small eyes to facilitate burrowing. It has been observed that both male and females have various scent glands on their bodies that secrete fatty acids and alcohols to deter nuisance arthropods, such as ants or other burrowing insects. The species is described as terrestrial and semi-fossorial, which makes them hard to observe and study. The color pattern is usually dark with patches of white scales, although occasionally after shedding all pigment will disappear, resulting in a white snake with only a small dark patch on its head. Scale coloring can also vary between pinkish... Wikipedia →

Possible
About 30% of wildlife watchers report a Mexican Burrowing Python sighting in Santa Rosa National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 37 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January and August
In those months about 40% of wildlife watchers report a Mexican Burrowing Python in Santa Rosa National Park on a given day, against under 5% in February and March, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Mexican Burrowing Python sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Santa Rosa National Park, in our data
Santa Rosa National Park is the only park on Wallace's Line with enough records to rate Mexican Burrowing Python sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mexican Burrowing Python is recorded against all the reptiles logged in Santa Rosa National Park (14 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.
