About
A stout mole salamander native to the eastern United States and Canada, recognizable by two irregular rows of yellowish-orange spots on a dark body; it is the state amphibian of Ohio and South Carolina
Size and behavior
Fossorial and nocturnal—rarely seen except after rains—these salamanders migrate en masse to vernal pools during spring’s “Big Night,” can autotomize their tails, and secrete a toxic milky fluid when threatened
Diet and nutrition
As ambush predators, adults feed on invertebrates in the forest floor; larvae are aggressive predators, sometimes cannibalizing smaller conspecifics when food is scarce
Temperate Forests & Ponds
More animals to meet
Conservation status
Listed as Least Concern by the IUCN due to its wide distribution and stable overall population; however, it relies on vernal pool habitats vulnerable to destruction and acid rain
Fun fact
Its embryos host a unique endosymbiotic green alga (Chlorococcum amblystomatis), which supplies oxygen and removes nitrogenous wastes—a rare example of vertebrate cells housing a microbe
