Thanks to a pressurized penis inflator and genitals flown in from across the U. We note gaps in knowledge, suitable platforms for future investigations (drones, bridges, boats, and coastal cliffs), and what is known about mating behavior in other porpoise species, including We photographed 144 mating events over an eight-year period (2010 to 2018) occurring in all seasons. Asymmetric genitalia and lateralized mating behaviors occur in several taxa, yet whether asymmetric morphology in one sex correlates or coevolves with lateralized mating behavior in the other sex Groundbreaking new research has been published on the sex lives of harbor porpoises under the Golden Gate Bridge. The male in front leaps high out of the water when approaching the female, who turns her body sidewise.
