Hokuriku Sansho-uo, Hokuriku Salamander
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
Hynobius takedai belongs to the family Hynobiidae, which is one of only two salamander families exhibiting external fertilization of eggs. This species breeds from January to April in pools of water from melting snow at the edge of forested areas. Large males may establish a territory from which they exclude other males. Two egg sacs are laid coiled around the base of reeds. The egg sacs have vague striations. The total number of eggs is 67-107. Most of the larvae metamorphose and leave the water by the onset of autumn (Goris and Maeda 2004).
