Amphibious sperm transfer in the Red-legged Salamander, Plethodon shermani.

Courtship is in the final stages. After the head-slap sequence shown in the previous clip, the female continues to straddle the male's gently undulating tail, while resting her chin on the dorsal surface of the base of his tail. After a few moments, the male deposits a white spermatophore on the substrate, then moves forward and away. The female moves forward, keeping her chin on his tail base, until her vent area is over the spermatophore, then backs up, lowers her vent, and picks up the spermatophore with her cloaca.
