The Eastern Tiger Salamander

Daily Critter Facts, Amphibian Facts, Salamander Facts

The eastern tiger salamander can be found from Canada on down south to the Mexico border, in the eastern half of North America. They prefer open, dry woodland habitats, prairies, and areas with damp soil. These are the largest land-based salamander in North America and 1 of the largest salamanders in the world, after the Japanese & Chinese giant salamanders and hellbenders. Due to their numbers, they are listed as Least Concern by the IUCN. However, their populations are decreasing throughout their range, due to habitat destruction.

First the Stats…

Scientific name: Ambystoma tigrinum
Weight: Up to 4.4+ ounces
Length: Up to 12+ inches
Lifespan: Up to 15 years

Now on to the Facts!

1.) Tiger salamanders prey on worms, snails, insects, frogs, smaller salamanders, slugs, and even each other.

2.) Badgers, bobcats, snakes, and owls prey on adults, whereas the larvae are preyed on by other amphibians and aquatic insects.

3.) Gular pumping (lowering & raising the floor of the mouth) is mainly used for breathing oxygen. However, as is the case with all amphibians, they can also breathe through their skin (dermal respiration).

4.) The tiger salamander can’t undergo augmentation (intentional loss of extremities) but if an extremity is lost, it will be regenerated but looks notably different.

5.) These salamanders are very loyal to the place of their birth and will travel a great distance to reproduce in the same location again and again.

But wait, there’s more on the eastern tiger salamander!

6.) Females deposit 1 or more egg masses, with up to 50 eggs per mass, each breeding season. Males fertilize the mass and life begins anew.

7.) It takes up to 3 months for a larval tiger salamander to reach maturity and leave the breeding pool.

Did you know…?
The largest recorded tiger salamander was measured at 13 inches!

8.) There is only a 50% chance that a female will breed more than once in her lifetime.

9.) Even though these salamanders are themselves immune to it, they are transmitters of Batrachochytrium dendrobatidis; the bacterium that causes the deadly chytrid fungus.

10.) They also can carry the ranavirus. This can cause mortality (death) in salamanders, frogs, and fish. Using tiger salamanders as fish bait dramatically increases the spread of the ranavirus. So don’t do it!

With over 50 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge. I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or in the air. I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!
