How do Salamandra reproduce?
- Breeding occurs on land, and the females deposit their young in water. S. salamandra is considered viviparous. The female retains the developing eggs, and the embryos derive their nourishment from the yolk. At birth the larvae are usually quite advanced, although some populations deposit young that have already metamorphosed.
How are salamanders fertilized?
- Salamanders eggs are fertilized by the female picking up spermatophore from the ground or water where it was deposited by the male; the salamanders lay the fertilized eggs either in water or on land depending on the specific species and produce larvae that hatch with gills, a tail and weak legs.
What is the sex life of a salamander?
- The sex life of salamanders is quite amusing. Throughout the breeding season, both sexes of the salamanders search for potential mates. This happens during the first warm rains of spring to steer clear of extreme environmental conditions.
How many eggs can a salamander lay at once?
- Salamanders evolve into adults that can breathe air, live on land and have strong legs. During reproduction, a salamander can lay up to 450 eggs in the water. Salamander species that lay eggs on land rather than water lay significantly less eggs at one time, ranging from seven to 30.
