The lady salamander that shuns male companionship may reap important benefits. For instance, when a predator snaps off her tail. New research from The Ohio State University compared an all-female population of mole salamanders to a related heterosexual species and found they grew their tails back 36 percent faster. The unisexual salamanders (part of the Ambystoma genus) contain DNA of up to five species and reproduce primarily by cloning themselves.
