Eastern Tiger Salamander - Ambystoma tigrinum tigrinum

Description: 5 7/8 - 9 ¾" (15 - 35 cm). This is our largest salamander. Highly irregular splotches olive to yellow color on black dorsum. Olive/yellow dorsum. Very plump, with 12-13 costal grooves.

Similar species in our area:
The spotted salamander (A. maculatum), however, adult tiger salamanders are significantly larger as are metamorphs.

Lifestyle: This species is listed as "Endangered" by the New York State Department of Environmental Conservation. It is fairly common at BNL but is uncommon or extirpated throught many of the other parts of L.I. Fossorial. Live in heavily forested areas with moist to dry soils in scattered populations throughout our area. Seldom seen, except during breeding. They live under logs and rocks and also underground in rodent and self made burrows. This is the largest salamander in the eastern U.S. Breeding occurs January to April. Gelatinous egg masses are attached to submerged vegetation. Larvae hatch during summer at about ½". They transform into adults when they reach about 4-7". Females lay 205-328 eggs deposited in 5-8 egg masses. Average mass is 41 eggs. ANY SIGHTINGS OF THIS SPECIES ON LONG ISLAND SHOULD BE REPORTED TO Jeremy Feinberg.

Four Toed Salamander - Hemidactylium scutatum

Description: 2 - 3 ¾" (5.1 - 9.5 cm). Belly is enamel-white with black speckles while dorsum is red/brown and sides gray. This species has four toes on hind legs, and often has a constricted area by the base of the tail. 13-14 costal grooves.

Similar species in our area: The lead phase of the redback salamander (Plethodon cinereus) may look similar, but has five toes and enamel-white belly. Rarely seen at BNL. It is unknown how common this species is at BNL because it has a very sensitive lifestyle.

Lifestyle: Uncommon at BNL, although its secretive lifestyle may hide biologists from learning its true abundance. Occurs in moist woodlands and shallow, vegetated wetlands. At BNL occurs in associations with red maple/sphagnum moss bogs and is almost always found under moss. Breeds late winter to early spring. Lays 18-40 eggs in nest cavity near water. Nests may be communal with more that 40 eggs. Larvae hatch late spring at ½" and enter water. Transform late summer. Females will stay with and protect their eggs for some time. Great care should be taken if handling this species because the tail is prone to breaking off at the constriction. ANY SIGHTINGS OF THIS SPECIES ON LONG ISLAND SHOULD BE REPORTED TO Jeremy Feinberg.
