Salamander
Salamanders are a group of amphibians in the order Caudata (also called Urodela) with long tails, slender bodies, and typically short limbs.
Salamanders are amphibians in the order Caudata (Urodela), known for their slender bodies, long tails, and moist skin. They are found mainly in the Northern Hemisphere and are famous for their ability to regenerate lost limbs and tails.
What it is
Salamanders are a group of amphibians with elongated bodies, short limbs, and long tails. They are not reptiles. Their skin is moist and they rely on damp environments. There are about 600 to 740 species worldwide, with new species still being described.
Why it matters
Salamanders are ecologically important as predators of small invertebrates and as prey for larger animals. Their remarkable ability to regenerate lost body parts, including limbs and tails, makes them a key model for biomedical research into tissue repair and regeneration.
Key details
Most salamanders live in moist habitats such as streams, ponds, forests, and under rocks or logs. They are carnivorous, eating insects, worms, snails, and small fish. Many species lay shell-less eggs in water, and young often hatch as aquatic larvae before metamorphosing into adults.
In short
- Salamanders are amphibians, not reptiles.
- They have moist skin and long tails.
- Many can regenerate lost limbs and tails.
- They live in damp habitats near water.
Salamanders are part of Canada’s native amphibian fauna, especially in moist forests, wetlands, and freshwater habitats across the country. Canadian readers may encounter species such as the eastern red-backed salamander and other woodland or aquatic salamanders.
