Tremblay's salamander (Ambystoma tremblayi) is a member of the family Ambystomidae from the United States of America and Canada. Reaching between 3¾ and 6⅜" (9.3 and 16 cm), the salamander is long and slender with many bluish-white markings. It is dark gray to gray-black and the area around the vent is black. Tremblay's salamander is a hybrid species of Jefferson salamanders (A. jeffersonianum) and blue-spotted salamanders (A. laterale). This hybridization created two all-female species: Tremblay's and silvery salamanders. These genetic curiosities possess three sets of chromosomes instead of the normal two.


Tremblay's salamanders breed with male blue-spotted salamanders from March to April. Eggs are laid singly or in small masses of 6-10 eggs on debris at pond bottom. The males' chromosome contribution only stimulates the egg's development; its genetic material is ignored. It is not often observed and its diet and lifestyle are unknown.

Habitat and range[edit]

These salamanders live on the bottom of deciduous forests from northern Wisconsin, northern Indiana, northern Ohio, and southern Michigan east through southern Quebec to the New England coastal plain.
