Walruses won the evolutionary jackpot when it comes to penis bones, and it’s a good thing because these massive creatures need all the help they can get. So, what makes the walrus baculum unique from the rest?

Walruses have the prestigious distinction of having the largest bacula on the planet. Bacula, or penis bones, are enigmatic structures that are possessed by males of various species across several mammalian orders. They aren’t true bones inasmuch as they are actually derived from outside of the skeleton – from connective tissue that forms at the very tip of the penis. Despite the fact that walruses have kind of won the evolutionary lottery of the penis bone, scientists cannot come to a specific agreement as to its exact function.  

The leading hypothesis as to the original function of the baculum is in helping to maintain erections. You can imagine that the Northern oceans (where mammals with the largest penis bones are found) are quite cold, and copulations most often occur in the freezing water. Copulation on land does happen sometimes, and it comes with its own hazards. If things get a little rough (as they often do), delicate phalluses could easily be crushed. So the bacula help to ensure that penises remain intact and functional.
