COSEWIC Status Reports
COSEWIC Assessment and Status Report on the Unisexual Ambystoma, Ambystoma laterale, Small-mouthed Salamander-dependent Population, Jefferson Salamander-dependent Population and the Blue-spotted Salamander-dependent Population, in Canada (2017)All-female populations of Ambystoma (i.e., unisexuals) are members of the Mole Salamander family Ambystomatidae. Their morphology is variable and is determined by their nuclear genomes. Unisexuals with two or more Blue-spotted Salamander (A. laterale) chromosome complements are black with various amounts of blue flecking, and have relatively short limbs and a narrower head. Unisexuals with two or more Jefferson Salamander (A. jeffersonianum) chromosome complements are larger, grey to brown with a small amount of blue flecking, and have relatively long limbs and a broader head. Unisexuals with two or more Small-mouthed Salamander (A. texanum) chromosome complements are grey, more slender, and have narrow heads.
