Sibon longifrenis, Stejneger's snail sucker or lichen-colored snail sucker, is a species of snake in the family Colubridae. It is found in Panama, Costa Rica, Honduras and Nicaragua. The Sibon longifrenis primarily feeds on amphibian eggs, particularly frog eggs, but will also feed on small oligochaetes and mollusks, such as slugs and snails. The absence of amphibian eggs in their diet may result in nutritional deficit and poor body conditions.

Possible
About 20% of wildlife watchers report a Mottled Snail-eater sighting in Tenorio Volcano National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 38 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Mottled Snail-eater in Tenorio Volcano National Park on a given day, against under 5% in August to October, the lowest months. That is one of Tenorio Volcano National Park's wettest months, with about 420 mm of rain against 120 mm in April.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Mottled Snail-eater sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 3 parks where we can rate Mottled Snail-eater sightings, Tenorio Volcano National Park has the highest daily chance: about 20%. Next come Braulio Carrillo National Park (Costa Rica, about 20%) and Arenal Volcano National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Mottled Snail-eater is recorded against all the reptiles logged in Tenorio Volcano National Park (18 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.
