The mating system and social structure of the vaquita have not been studied.
Although the mating system and social structure of the vaquita have not been studied, it has been inferred from the large testes size, (almost 3% of body mass,) reverse sexual dimorphism, (females are bigger than males,) and small group sizes that sperm competition plays an important role in the species’ reproductive strategy.
