A lengthy and ritualized mutual dance precedes copulation in all pipefish. In S. typhle, females transfer eggs to a brood pouch under the male’s tail, where he then fertilizes them. Subsequently, embryos are nourished and oxygenated in the pouch until birth several weeks later (Berglund et al., 1986a,b).
