OTHER NAMES

English: Mud pet, water canine; French: Ambystome tigré German: Tigerquerzahnmolch; Spanish: Salamandra tigre.

TAXONOMY

Salamandra tigrina Green, 1825, Near Moore’s city (Moorestown), New Jersey, United States. Up to six subspecies are acknowledged within the United States. Formerly, the California tiger salamander, Ambystoma californiense, was thought-about a subspecies of A. tigrinum. Considerable debate stays over whether or not the species ought to be thought-about one or a number of species.

PHYSICAL CHARACTERISTICS

This is a big, strong species that grows to 13.eight in (350 mm) in size. Adults differ broadly in shade sample, from black with shiny yellow spots and bars or vague yellow flecks and reticulations to pure brown or black. In the central United States and Rocky Mountains, tiger salamanders might breed as paedomorphs or metamorphs; elsewhere (together with A. californiense) they at all times metamorphose.

DISTRIBUTION

The tiger salamander is essentially the most broadly distributed salamander in North America, starting from southern Canada south, roughly to the border of Mexico and the United States. It is absent from the Appalachian Mountains, the northeastern United States, elements of the southern United States, and the Great Basin, together with the Mojave Desert. In California it's changed by the California tiger salamander, A. californiense.

HABITAT

Primarily a grassland-associated species, the tiger salamander is present in prairie and open, dry woodland habitats. It ranges from sea stage to an elevation of greater than 11,000 ft (3350 m).

BEHAVIOR

Adults of this species spend just about all of their lives in underground rodent burrows. They emerge and migrate to breeding ponds throughout spring rains and generally might be discovered on the floor at night time throughout heavy rains.

FEEDING ECOLOGY AND DIET

A fearsome predator, the tiger salamander is a feeding generalist. As larvae, they eat prey starting from tiny zooplankton to tadpoles and even one another. In captivity they eat prey virtually as giant as they're. On land they eat every kind of invertebrates and small vertebrate prey.

REPRODUCTIVE BIOLOGY

Like many different members of the tiger salamander complicated and the northwestern salamander group, many tiger salamander populations differ by way of metamorphosis, with each metamorphs and paedomorphs coexisting in everlasting or semipermanent water our bodies.

CONSERVATION STATUS

In many areas tiger salamanders are considerable and beneath no apparent threats, whereas in different areas they're Endangered. The Sonoran tiger salamander, A. t. stebbinsi is listed as Endangered beneath the U.S. Endangered Species Act, and the associated California tiger salamander ( A. californiense) is listed as Vulnerable by the IUCN. Across its vary the tiger salamander can not coexist with predatory fish, and the introduction of bass, catfish, and different species poses a menace to these salamanders.

SIGNIFICANCE TO HUMANS

Larval tiger salamanders are sometimes the highest predator within the vernal swimming pools and ponds the place they stay, and they're due to this fact an essential a part of many aquatic ecosystems. In many elements of the United States, tiger salamander larvae are commercially priceless as fish bait. Particularly within the southwestern United States, these “water dogs” are bought in giant numbers.
