ALPINE NEWT
Ichthyosaura alpestris
DESCRIPTION
Alpine Newt (Ichthyosaura alpestris) is a small amphibian known for its striking coloration, particularly in males during the breeding season when they exhibit bright orange or yellow bellies. This species is primarily aquatic, spending much of its life in ponds and streams, but it also inhabits moist terrestrial environments during the non-breeding season. They are known for their ability to adapt to various altitudes, often found in mountainous regions across Europe.
FUN FACTS
- Alpine Newts are capable of regenerating lost limbs, a fascinating ability that has drawn the interest of researchers studying regeneration
- | During the breeding season, males perform elaborate courtship displays, including swimming in circles and showing off their vibrant colors to attract females
