Geophis hoffmanni, also known commonly as Hoffmann's earth snake, is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is native to Central America. The specific name, hoffmanni, is in honor of German naturalist Karl Hoffmann.
G. hoffmanni is found in Costa Rica, Honduras, Nicaragua, and Panama. The preferred natural habitat of G. hoffmanni is forest, at altitudes of 18–2,100 m (59–6,890 ft), but it is also found in disturbed areas such as farms and gardens.
A small species of snake, the holotype of G. hoffmanni has a total length (including tail) of 24.5 cm (9.6 in) (W. Peters, 1859). The dorsal scales are arranged in 15 rows throughout the length of the body. There are five or fewer upper labials, and the posterior chin shields contact each other. The ventrals number 114–131, and the subcaudals number 23–32. Adults are uniformly dark brown or black dorsally, and are white or cream-colored ventrally. Juveniles have a paler nuchal collar.
G. hoffmanni is terrestrial and secretive, sheltering under logs and rocks. G. hoffmanni is oviparous. ��2... Wikipedia →

With luck
About 10% of wildlife watchers report a Hoffmann's Earth Snake sighting in San José on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 11th most-seen of the 24 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Hoffmann's Earth Snake in San José on a given day, against under 5% in January to April, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Hoffmann's Earth Snake 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 San José, in our data

GBIF citizen-science records
It is estimated from how often the Hoffmann's Earth Snake is recorded against all the reptiles logged in San José (20 verified sightings), 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.
