Despite the whale's size, scientists have trouble locating and studying the cetacean in the vastness of the ocean, leaving many questions about the mammal's life history, particularly its mating and courtship behaviors. Blue whales Balaenoptera musculus are found worldwide, with different regional populations forming distinct subspecies. Scientists believe they reach sexual maturity between 5 and 15 years of age, and have a gestation period that lasts 10 to 12 months.

The research team was enjoying a lunch break on the water after completing a morning of transect surveyswhen we noticed a nearby competition pod. We realized that the whales were headed towards us and decided to put our GoPro camera in the water to document the behavior. To our amazement, we had filmed something we never expected to see — one of the whales was swimming with its penis out!

In order to provide the whale with a more streamlined design when swimming and to protect its sexual organs from injury the blue whales penis is often hidden within a genital slit during normal daily activities and becomes exposed during sexual intercourse. Penis size for the blue whale can vary depending on genetics and the overall size of the whale with the average penis length estimated to be between 8 — 10 ft.

Right now, penises get far more attention than vaginas in the science world. As science journalist Ed Yong recently notedthis is a troublesome trend. First, a gender bias in research subjects skews our basic understanding of sexual selection and evolution; as a result of a preference for sperm and penis studies over female genital investigations, we have underestimated the role of female choice and selection in influencing the course of evolution.

Sure, the structure was important 40 million years ago, when the ancestors of these seagoing mammals were walking around on land and had actual legs attached to actual hips. No wonder evolutionary biologists have long considered these small, apparently useless bones purely vestigial, destined eventually to vanish. That in turn would give him more descendants with the ideal, pelvis-anchored musculature to keep their partners happy, producing even more descendants, and so on.

Whales are polygamous mammals, with females giving birth to live young and nursing them for several months. During breeding season, the male, or bull whale, copulates underwater with the female, or cow, in a complex mating ritual that varies widely from species to species. Mating entails long migrations to oceanic breeding grounds, vocalizations or songs and, sometimes, large groups of male whales, such as humpbacks, competing for females in violent displays of dominance.
