Spawning Behavior (Hasumi)

Spawning Behavior

Several breeding males of Salamandrella keyserlingii around a pair of egg sacs newly deposited, and a pair of egg sacs previously deposited and marked by a number-tape (upper), in a fen water during April-May (photographed around 2000-2200 h on 5 May 1996). Each sac includes around 100 eggs. The egg sacs just deposited assume a white-blue, fluorescent color (also see Egg Sacs of Hynobius kimurae). There are many dead leaves of sedges throughout the fen as a substrate for egg sac deposition.
