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. == Behaviour == 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.
