Whatever substrate is used, make sure it does not become soggy or waterlogged. When a simple substrate like paper towels is used it will need to be changed often, up to several times each week, while a soil mixture may be okay for months so long as it is spot cleaned regularly. Other substrate options include leaf litter or clumps of moist paper towels layered together. Be careful to avoid soil that contains perlite, vermiculite, small pieces of bark, or gravel. A mixture of coconut husk fiber and cypress mulch works well, as do any number of other soil mixtures. A secure screen cover should be used to prevent escapes.Ĭhoose a substrate that holds moisture, is not abrasive, and allows the salamander to easily dig and burrow. A standard 15 gallon aquarium that measures 24 inches long by 12 inches wide by 12 inches high (61 cm by 30 cm by 30 cm) is enough space for one adult. Tiger salamanders are best kept individually. They have been bred on a couple occasions but those for sale in the trade are almost entirely wild-caught. If it is legal and you live in an area with tiger salamanders, it may be a better option to collect one of your own rather than purchasing it at a pet store. Tiger salamanders are seasonally available in the North American pet trade, collected from the wild and supplied to pet dealers during spring breeding migrations. They breed in these water bodies in early spring, often in the days just after the first rains of the year, when the ground thaws and snow melts. They can be found in a wide range of habitats, including wooded areas, marshlands, and meadows, but always near ponds that don’t have fish or small lakes. They usually excavate these themselves, but may also take over holes and shelters dug by other animals. Tiger salamanders spend most of their time underground where they live in burrows. Native to much of the United States, southern Canada and northern Mexico. Young salamanders can be spotted but this polka-dot pattern changes as they age. Tiger salamanders are variable in color and pattern, and range from olive-brown with black blotches, to dark black with yellow rings and bars, to bright green with black lines and swirls. Adults can grow to 13 inches (33 cm) in total length, but most end up closer to 9-10 inches long (23 and 25 cm). One of the largest terrestrial salamanders in the world. We suggest creating a formal nomenclatural distinction between cannibal morph larval phenotypes and cannibal morph paedotypic phenotypes.Tiger Salamander, Eastern Tiger Salamander, Barred Tiger Salamander Size tigrinum), making it an excellent region to examine subspecific morphological features in light of shared ecological factors. The study wetland is located near the convergence of four recognized (pending revision) tiger salamander subspecies (A. tigrinum from nearby (about 160 km) northwestern Iowa in particular the pair of caudolateral tooth ridges has smaller teeth in individuals from the A. The vomerine tooth hypertrophy characteristic of cannibal morphs described here differs from the cannibal morph A. At least one cannibal morph was paedotypic. This population contains paedotypic animals and a small percentage of cannibal morphs. We report characteristics of a previously unknown population of Ambystoma tigrinum mavortium (barred tiger salamander) from eastern South Dakota, a location that extends the formerly known range of this subspecies about 150 km north.
