Luschmans salamander is part of an ancient lineage that diverged from their closest relatives around 200 million years ago, an incredible 135 million years before the extinction of the dinosaurs! It is unusual among the amphibians in that it bears live young, with two fully developed offspring being born after 5 to 8 months. The courtship is also bizarre, with males inserting a warty projection at the base of their tail into the females cloaca (reproductive opening) prior to the transfer of an external sperm packet. Restricted to a range the size of Manhattan Island, it is chiefly threatened by its small area of occurrence, making it vulnerable to ecological disasters and climate change.
