Abstract: Lay Summary Pipefish females need twice as many males as they get: Females in 2 sex role–reversed species produced twice as many eggs as males could care for. In 1 species, males preferred larger females, in the other not. Thus, although potential reproductive rates were similar between species, mate choice was not. Obviously, costs and benefits of choice were more important than potential reproductive rates to understand mate choice.
