Tiger Salamander

Tiger Salamander facts at a glance

How big is a tiger salamander?

An adult tiger salamander measures 20 cm long — about 12% of the height of an average adult person (1.73 m) — and weighs around 130 g, a small fraction of an average adult’s body weight (70 kg).

Behavior and life underground

Tiger salamanders are powerful diggers that spend most of the year in burrows, sometimes more than half a meter deep, which protects them from heat, cold, and drought. They are largely nocturnal and emerge on rainy nights. Adults migrate to breeding ponds in early spring, often during the first warm rains.

Diet and feeding

They are voracious carnivores that eat earthworms, insects, slugs, and other invertebrates, and large adults may take small frogs, baby mice, or even smaller salamanders. Larvae are aquatic predators that feed on tiny invertebrates and, in crowded ponds, sometimes other larvae. Their broad diet helps them grow quickly.

Habitat and range

The tiger salamander ranges widely across North America, from southern Canada through much of the United States into Mexico. It favors grasslands, woodlands, and farmland with access to fishless ponds for breeding. Because it relies on temporary pools, it is sensitive to changes in water and soil.

Conservation

Overall the species is listed as Least Concern, but some local populations are declining from habitat loss, road mortality, and pollution. Certain regional subspecies are more threatened and receive special protection. Maintaining clean breeding ponds and connected habitat is key to its future.

Did you know? Tiger Salamander facts

• The tiger salamander is one of the largest land-dwelling salamanders in North America, named for the yellow blotches that stripe its dark body.
• Tiger salamanders typically reach 15 to 30 cm (6 to 12 in) in length, making them one of the largest land-dwelling salamanders in North America.
• They are carnivores that eat earthworms, insects, and slugs, and large adults may even take small frogs, baby mice, or smaller salamanders.
• They live across much of North America in grasslands, woodlands, and farmland, spending most of their time in burrows and returning to ponds to breed.
• Tiger salamanders can live about 10 to 16 years, and well-cared-for individuals in captivity sometimes live longer.
• Conservation: Least Concern (IUCN).

Communication

• Tiger Salamander uses scent, posture, and vocal signals to mark territory and coordinate social behaviour.
• Communication intensity often peaks during breeding seasons and territorial disputes.

Habitat & range

Grassland, woodland, and farmland with ponds

Ecological role

Tiger Salamander acts as a predator that helps regulate prey populations and maintain balance in grassland, woodland, and farmland with ponds.
