Marbled Salamander - Ambystoma opacum
The marbled salamander is 3-5 inches in length. It has a black body with white or silvery-gray markings. The female has gray markings and the male has white markings. It has 11-12 costal (vertical) grooves.
The marbled salamander is found from southern New Hampshire to northern Florida, and west to southern Illinois, southeast Oklahoma, and east Texas. It is also found around Lake Erie and Lake Michigan and in southwest Missouri and along the northern border of Ohio and Indiana.
The marbled salamander lives in forests and woodlands. It is found in a variety of habitats, from moist sandy areas to dry hillsides. It spends most of its time in a burrow, in leaf litter, or under bark or a log.
Adult marbled salamanders eat invertebrates including earthworms, slugs, snails, centipedes, and a variety of insects. Larvae eat zooplankton. As they grow larger, they eat tadpoles, insects, and other salamander larvae.
The marbled salamander breeds from September to October in the northern part of its range and from October to December in the southern part of its range. The marbled salamander mates and lays its eggs on land. The female lays 50-200 eggs, one at a time, in a depression under a log or in a clump of vegetation that fills with water when it rains.
Except for during breeding season, marbled salamanders are solitary creatures.
