Jefferson salamanders (Ambystoma jeffersonianum) have long, thin bodies. The eggs are laid in water in early spring,
hatch in spring, and undergo metamorphosis to adults in mid to late summer.
Adults live in forests and near bodies of water.
Jefferson Salamanders can interbreed with Blue-spotted salamanders
and this hybridization has resulted in two species composed solely of
females: the silvery and Tremblay’s salamanders.
Males can still mate with these all-female species but their sperm
doesn’t contribute to the genetic material of the offspring, it merely
stimulates the development of the eggs (Behler, 1989).
