  abstract = {{A}ssortative mating by size has been argued to be widespread in the animal kingdom. {H}owever, the strength of size-assortative mating is known to vary considerably between species and the underlying mechanisms promoting this inter-specific variation remain largely unexplored. {S}ize-assortative mating has been proposed to be particularly strong in simultaneous hermaphrodites, i.e. organisms that produce male and female gametes at the same time. {H}ere, we build on this hypothesis by arguing that size-assortative mating mediated by sexual selection is generally stronger in reciprocally mating hermaphrodites compared with unilaterally mating species and separate-sexed organisms. {W}e report a series of empirical tests suggesting that size-assortative mating in the unilaterally copulating freshwater snail {P}hysa acuta is caused by spatial clustering of similar-sized individuals and not by mate choice. {I}n addition, we present a meta-analysis testing, for the first time, the hypothesis that sexual selection-mediated size-assortative mating is stronger in reciprocally copulating simultaneous hermaphrodites. {O}verall, we found significant size-assortative mating across 18 tested species and substantial inter-specific variation. {I}mportantly, part of this variation can be explained by mating type, providing support for the hypothesis that size-assortative mating is stronger in reciprocally mating hermaphrodites compared with unilaterally mating species. {W}e highlight potential pitfalls when testing for sexual selection-mediated size-assortative mating and discuss the need for more experimental and comparative approaches in order to resolve the observed variation in the strength of size-assortative mating among species.},
