TIGER SALAMANDER
Ambystoma tigrinum
DESCRIPTION
Tiger Salamander (Ambystoma tigrinum) is a large, stocky salamander characterized by its striking yellow or white spots against a dark background, which can vary from black to olive green. This species is primarily nocturnal, emerging at night to hunt for food and engage in breeding activities during the rainy season. They inhabit a variety of environments, including grasslands and forests, often relying on temporary ponds for breeding, which are crucial for their reproductive cycle.
FUN FACTS
- Tiger Salamanders are known for their impressive ability to regenerate lost limbs, a trait shared with many amphibians
- This regeneration capability allows them to recover from injuries that would be fatal to many other species
- | They have a unique life cycle that includes both aquatic larvae and terrestrial adults, showcasing a fascinating transformation as they grow
- The larvae are often brightly colored and can be quite different in appearance from the adult form
