Eastern Tiger Salamander

Our Collection
Here at the zoo, we have one Eastern Tiger Salamander. We received him from a private breeder in the fall of 2019 as a juvenile. He calls the Welcome Center home but has incredible camouflage and can be quite difficult to spot!

These salamanders usually grow to a length of 6–8 inches. They are characterized by having markings varying in color on the back of their head, body, and tail. The coloring of these spots range from brownish yellow to greenish yellow, while the rest of their back is black or dark brown. They have short snouts, thick necks, strong legs, and lengthy tails.
Salamander Range 2
This species is most commonly found on the Atlantic coast from New York down to Florida. They are known, however, to be the widest ranging species of salamander in North America and have been found in smaller populations from coast to coast.

Tiger salamanders habitats range from woodlands crowded with conifer and deciduous trees to grassy open fields. These amphibians are secretive creatures that spend most of their lives underground in burrows, making them difficult to spot. One significant requirement these salamanders need to thrive is loose soil for burrowing. Tiger salamanders are almost entirely terrestrial as adults, and usually only return to the water to breed. The ideal breeding condition for tiger salamanders ranges from wetlands, such as cattle ponds and vernal pools, to flooded swamps.

They are extremely loyal to their birthplaces, and will travel long distances to reach them. However, a single tiger salamander has only a 50% chance of breeding more than once in its lifetime. The tiger salamander's ideal breeding period is somewhere between the late winter and early spring, once the ground is warm enough and the water is thawed. Males nudge a willing female to initiate mating, and then deposit a spermatophore on the lake bottom. About 48 hours after insemination, the female is ready to deposit her eggs in the breeding pool. She carefully attaches the eggs to secure twigs, grass, and leaves at the bottom of the pool to ensure her eggs safety. In about 12-50 days, the eggs will be fully hatched and ready to mature in the pool. It takes a tiger salamander approximately 3 months to reach full maturity and leave the breeding pool.
Tiger Salamander larvae
The larva is entirely aquatic, and is characterized by large external gills and a prominent caudal fin that originates just behind the head, similar to the Mexican axolotl. Limbs are fully developed within a short time of hatching. Some larvae, especially in seasonal pools and in the north, may metamorphose as soon as feasible. These are known as small morph adults. Other larvae, especially in ancestral pools and warmer climates, may not metamorphose until fully adult size. These large larvae are usually known as 'waterdogs', and are used extensively in the fishing bait and pet trades. Some populations may not metamorphose at all, and become sexually mature while in their larval form. These are the neotenes, and are particularly common where terrestrial conditions are poor.

Life Expectancy
In the wild:  12-15 years
In human care:  15-20 years

Natural Diet
Their diet consists largely of small insects, frogs, and worms, although it is not uncomTiger Salamandermon for an adult to turn cannibalistic and consume its own kind. Cannibalism in these salamanders can almost always be traced back to a large volume of competing predators and lack of prey in the area.
