Hasumi, M., Y. Hasegawa, and H. Iwasawa: Long-term maintenance of egg-fertilizability in water in the salamander Hynobius nigrescens. Japanese Journal of Herpetology (Japan, Domestic; English or Japanese) 15(2): 71-73, December 1993.
Abstract: Eggs in an egg sac of Hynobius nigrescens have nearly 100% fertilizability even after three hour-long immersion in water. Promptly inseminating in water seems to be extrinsic embryologically in this species.
