The Marbled Salamander is a medium-sized amphibian known for its striking black body adorned with white or gray marbling. This species, scientifically named *Ambystoma opacum*, typically measures between 3 to 5 inches in length. They are primarily found in the eastern United States, inhabiting woodlands and areas near temporary ponds. Marbled Salamanders are unique among salamanders because they breed in the fall. Females lay their eggs in moist soil or under leaf litter, where they remain until the winter rains fill the ponds. This adaptation allows their larvae to develop in water while avoiding competition with other amphibians, such as American Toads and Spring Peepers.
