NEWT
Notophthalmus
DESCRIPTION
Newts are small to medium-sized amphibians that exhibit a range of colors, often featuring bright orange or yellow with black spots. They have a slender body, a long tail, and smooth skin, which can vary in texture depending on the species and life stage. Newts are known for their aquatic larval stage, during which they develop gills, and they often return to water bodies to breed, showcasing complex courtship behaviors.
FUN FACTS
- Newts are capable of regenerating lost limbs, tails, and even parts of their heart and eyes, making them a subject of scientific research into regenerative medicine
- | During the breeding season, male newts perform intricate courtship dances, which can include tail waving and the release of pheromones to attract females
