The marbled salamander (Ambystoma opacum) is a species of mole salamander found in the eastern United States. The marbled salamander is a stout, black and white banded salamander. It exhibits sexual dimorphism with bands of females tending to be light gray, while those of males are bright white. Males also have a larger proportion of white dorsal surface area relative to females. Females have been reported to have more asymmetrical dorsal markings, while the males have more symmetrical markings. Like most salamanders, they go through metamorphosis including an aquatic life stage. Juveniles have white flecks that eventually develop into bands as they reach adulthood. Adults can grow to about 11 cm (4 in), small compared to other members of its genus. Like most of the mole salamanders, it is secretive, spending most of its life under logs or in burrows.
Marbled salamanders are found in the eastern United States, from southern New England to northern Florida, and west to Illinois and Texas. Their habitats are damp woodlands, forests, and places with soft and wet soil. Seasonally flooded areas are essential for breeding, but the adult salamanders... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Marbled Salamander is recorded against all the amphibians logged in Congaree National Park (52 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.
