The Gulf Coast toad (Incilius valliceps) is a species of toad native to eastern and southeastern Mexico and Central America as far south as Costa Rica. The Gulf Coast toad is a medium-sized toad species, ranging from 2.5 to 10.2 cm (1 to 4 in) in length. Their back varies in color from nearly black, to shades of brown and grey with a distinctive white or yellowish colored stripe down the center, and sometimes lighter colored patches on the sides. Their underside is yellow or cream colored. Their back is covered in small tubercles, while their underside is normally devoid of them.
I. valliceps has the most extensive ridging of any toad in its geographic range. The ridges extend from the nose, to the back of the head, and with a branch that wraps around the back side of the eye. The Gulf Coast toad is found in a wide range of habitats, including open grassland, semi-arid regions, light forest, and even suburban backyards. They are typically found not far from a permanent water source, which they use for breeding in the spring, but they are capable of travelling long distances while foraging for food.

Possible
About 30% of wildlife watchers report a Central American Gulf Coast Toad sighting in San Pedro Sula on a given day, based on 25 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
September and December
In those months about 50% of wildlife watchers report a Central American Gulf Coast Toad in San Pedro Sula on a given day, against under 5% in February–March and November, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Central American Gulf Coast Toad sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only San Pedro Sula, in our data
San Pedro Sula is the only city on Wallace's Line with enough records to rate Central American Gulf Coast Toad sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Central American Gulf Coast Toad is recorded against all the amphibians logged in San Pedro Sula (25 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.
