Meet Alf

Alf might not roar like a tiger, but with his bold stripes and stealthy habits, he’s a true ambassador for his kind. As one of the largest land-dwelling salamanders in North America, Alf is a fascinating example of how life thrives beneath the surface—literally!

A Master of Underground Living

Tiger Salamanders like Alf are well known for their burrowing behavior. They’re part of the mole salamander family, equipped with strong limbs and broad heads that make them expert diggers. In the wild, they spend most of their adult lives underground, only emerging at night or during rainstorms. At the zoo, Alf enjoys enrichment activities that mimic his natural habitat, such as soft soil to burrow in, leafy bedding, and hollow log hides. These features help keep him safe, stimulated, and stress-free.

Where Alf Comes From

Tiger Salamanders are widespread across North America. They inhabit a variety of environments including woodlands, grasslands, and marshes—from southern New York down to Florida along the Atlantic Coast, and across much of the central and western U.S., with some populations in southern Canada. They thrive in places with loose, moist soil and plenty of cover, which provide the perfect conditions for their underground lifestyle.

A Voracious Carnivore

Don’t let the cute face fool you—Tiger Salamanders are carnivorous hunters. In the wild, they feast on worms, insects, slugs, snails, and sometimes even small amphibians, reptiles, or young mice. At the zoo, Alf dines on crickets that are dusted with calcium and vitamins, with an occasional treat of roaches or mealworms to keep his menu interesting and his body healthy.

Built for Two Worlds

As amphibians, Tiger Salamanders live part of their lives in water and part on land. They start life as aquatic larvae with external gills and then undergo metamorphosis, transforming into land-dwelling adults with lungs. Like all amphibians, they absorb oxygen—and toxins—through their skin, so a clean, damp environment is essential for their survival.

Living Long, Living Quietly

Though often hidden from sight, Tiger Salamanders can live impressively long lives. In the wild, they may live 12–16 years, but in human care, like at the zoo, they can live up to 25 years or more. Alf is a testament to the resilience of his species when provided with the right environment, diet, and care.

Status: Least Concern

Why Alf Matters

Even though Tiger Salamanders are currently listed as Least Concern, local populations are declining due to habitat loss, water pollution, and disease. Because they respire and drink through their skin, they are especially vulnerable to environmental changes. This sensitivity makes them an excellent indicator species—when amphibians like Alf are thriving, it’s a sign that their ecosystem is healthy too.

By learning about animals like Alf, we gain insight into the importance of preserving wetlands, reducing pollution, and protecting native wildlife. Every small step toward conservation helps safeguard the future of species like Alf and the delicate ecosystems they depend on.
