How does the Salamander reproduce?
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. Male salamanders “woo” their possible mate by giving off pheromones directed to the female salamanders. If the female wants to mate, she will participate in the dance wherein the “couple” will walk or swim around each other.
