Red salamander ( Pseudotriton ruber )
|(Sonnini de Manoncourt & Latreille , 1801)|
The skin of the 10 to 15 centimeter long animals is purple-brown to carmine-red in color and has irregular dark spots. The young animals appear lighter than the adults.
Against its predators, such as forest birds, skunks or raccoons , the species develops a skin toxin , which was formerly known as pseudo tritotoxin . These are unspecified toxins , including leptoxin .
The red salamander lives in the southeastern USA , south of New York to east of the delta of the Mississippi River in damp, cool forests and spring areas up to 1,500 meters above sea level. It is both aquatic and land-based; in winter he is only in the water. On land, the animals hide under stones, pieces of bark and wood.
Way of life
Food includes practically all animals to be overwhelmed. Occasionally other small salamanders are also eaten. Small prey are caught with the sling tongue, which can be snapped out and drawn in again within eleven milliseconds.
The mating season lasts from spring to autumn. The female can store the sperm in her body and lays 50 to 100 eggs in the water under stones or wood in early autumn. In the first months of winter, larvae about two centimeters long hatch . After 27–31 months in the water, the young animals undergo metamorphosis and go ashore. In males, sexual maturity usually takes place with a size of 53–63 mm (usually after 4 years), in females usually with a size of 55–68 mm (usually after 5 years).
