The spotted salamander (Ambystoma maculatum), also known commonly as the yellow-spotted salamander, is a species of mole salamander in the family Ambystomatidae. The species is native to the eastern United States and Canada. It is the state amphibian of Ohio and South Carolina. The species ranges from Nova Scotia, to Lake Superior, to southern Georgia and Texas. Its embryos have been found to have symbiotic algae, Chlorococcum amblystomatis, living in and around them, the only known example of vertebrate cells hosting an endosymbiont microbe (unless mitochondria are considered).
The spotted salamander is about 15–25 cm (5.9–9.8 in) long (tail included), with females generally being larger than males. It is stout, like most mole salamanders, and has a wide snout. The spotted salamander's main color is black, but can sometimes be a bluish-black, dark gray, dark green, or even dark brown. Two uneven rows of yellowish-orange spots run from the top of the head (near the eyes) to the tip of the tail (dorso-lateral ranging). The spotted salamander's spots near the top of its head are more orange, while the spots on the rest of its body are more yellow. The underside of the... Wikipedia →

With luck
About 10% of wildlife watchers report a Spotted Salamander sighting in Washington on a given day, based on 139 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 18 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February–April and August–November
In those months about 10% of wildlife watchers report a Spotted Salamander in Washington on a given day, against under 5% in May–July and December–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Spotted Salamander sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Spotted Salamander sightings, Washington has the highest daily chance: about 10%. Next come Boston (United States, about 10%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Spotted Salamander is recorded against all the amphibians logged in Washington (139 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.
