Reproduction
Not much is known about the reproductive behavior of Eurycea lucifuga, except that it most likely resembles that of Eurycea bislineata. The male begins by rubbing his chin and cheek against the female's nasolabial grooves. The male then performs pelvic lifts to induce the tail-straddling position in which the female mounts the male. The male deposits a spermatophore, which the female uses to fertilize her eggs. The eggs are deposited in small pools, where they hatch 10-20 days later. The larvae grow for about six months before migrating to nearby streams.
