    The persistent embrace of onychophorans: What determines copulation duration in velvet worms?
    (Universidad de Costa Rica (Costa Rica), 2019) Monge-Nájera, Julián; Barquero González, Pablo; Morera, Bernal
    In the only onychophorans mating that has been photographed, instead of fleeing, the couple remained together despite being manipulated. Why? The duration of copulation in onychophoran sis possibly controlled by the female, larger and stronger than the male, probably with the participation of dopamine and γ-aminobutyric acid. Insemination through the body wall can be a male mechanism to overcome female defenses.
