These organs may confer a capacity to locate food in the water column and/or on the substrate, and also for mate recognition
Several studies have shown possible causes and explanations for the failure in mate recognition
Species-specific fertilization is a type of mate recognition
that is amenable to study because it involves direct interaction of recognition molecules on the surfaces of just two cell types, the sperm and the egg.
Undoubtedly, many mate recognition
signals result in conspecific identification, but the signals still may vary within a species with important evolutionary consequences.

Pair-living species may not (and do not need to) depend on distance sex pheromones for mate recognition
Several studies have focused on visual cues provided by the presence of male foreleg tufts in this species, and their role in female mate recognition
and preference (Scheffer et al.
Divergence of mate recognition
systems among conspecific populations of the plethodontid salamander Desmognathus santeetlah (Amphibia, Plethodontidae).
The genetic basis and evolution of acoustic mate recognition
signals in a Ribautodelphax planthopper (Homoptera, Delphacidae) I.
Female preference for symmetrical males as a by-product of selection for mate recognition
Related species may have similar ecological requirements as well as sufficiently similar mate recognition
systems for interbreeding to occur.
There are four results: females always prefer conspecific calls; most heterospecific calls do not elicit phonotaxis; some heterospecific calls do elicit phonotaxis and thus are effective mate recognition
signals; and females prefer conspecific calls to which a component of a heterospecific call has been added to a normal conspecific call.
