Identification

Blue-spotted salamander is a medium-sized, very cold-tolerant, mole salamander. It occurs in the northern United States and southern Canada from Quebec and New Jersey in the east to Iowa and eastern Manitoba in the west. In Minnesota it is common in the northeast and there are scattered populations in remnant forests in the south. It is found in flat forested areas with permanent ponds. It is often discovered under logs. Adults are 3 to 5 (7.6 cm to 12.9 cm) long. Females are slightly larger than males.

The body is stout with four well-developed limbs that project sidewards. The trunk is cylindrical. The tail is broad and oval at the base, becoming cylindrical as it approaches the tip. It is long, comprising about 40% of the salamander’s total length. The skin is soft, moist, and dark brown, black, or bluish-black. There are numerous pale blue or bluish-white spots and flecks on the lower sides of the trunk and tail, fewer or absent on the upper (dorsal) surface. There are usually 12 or 13, sometimes 14, prominent vertical depressions (costal grooves) on each side between the forelimbs and the ventral area. The belly is usually lighter and flecked. The vent is black.

The head is moderately large, distinctly wider than the neck.

The legs are relatively short but the toes are relatively long (compared to other salamanders).

Juveniles are dark brown. They have yellowish blotches on the back and a yellow stripe on each side.

Species

 

 
Larval Food

Insects, mosquito and other insect larvae, water fleas, copepods, and other small aquatic invertebrates.

 
Adult Food

Earthworms, beetles, spiders, centipedes, snails, slugs, and other invertebrates.

 
Life Cycle

Breeding occurs in April in small woodland ponds and ditches. The female lays eggs individually or in groups of 2 to 4, attaching them to leaves or other debris at the bottom of the pond. The eggs hatch in about a month.

Adults are not freeze tolerant. It is thought that they burrow below the frost line to overwinter.

 
Behavior

The adult spends most of the year under a log or other cover. When threatened it holds its tail up and curved over the body. Small, granular glands, concentrated mostly on the tail, exude a milky, unpleasant tasting liquid in response to a predator.

About

Published on Oct 4, 2015

Look who I met under my boat today a pair of Blue-spotted Salamanders (Ambystoma laterale) This is a relatively slender blue-black salamander with whitish or blue spots on its back. It has four toes on its front feet and five on its hind feet. The costal (rib) grooves are very pronounced along the body between the front and rear legs. A triploid variant of this species, consisting exclusively of females, is found in parts of northern Wisconsin. The variants tend to be longer and paler than the blue-spotted salamanders. Blue-spotted salamanders prefer both northern and southern hardwoods and coniferous forests. They are often abundant in lowland hardwood forests. They tolerate dryer conditions than most Wisconsin salamanders, often living in forests with sandy soils. Adults eat many types of invertebrates including earthworms and insects.
