Males of certain species have evolved mating behaviors in which they forcefully attempt to mate with and inseminate females, often employing grasping techniques. These male grasping devices exist to increase the duration of copulation and restrict females from mating with other males. They are in some ways a form of mate guarding. While some ...
The dolphin might be displaying mating behaviour, he said, noting that it was seen attempting “to press his genitals against people” in 2022 and 2023. He added, however, that many injuries ...
In Peru, dusky dolphins are killed in large numbers (10,000–15,000 per year) and used as shark bait or for human consumption, which has led to a status of Vulnerable for the Peru subspecies. [65] Compared to more northern-living marine mammals, dusky dolphins are less contaminated by marine pollutants like DDT and persistent organic pollutants.
