The 22-Inch Penis Bone
Walruses have one of the largest penis bones (baculums) of any mammal — up to 22 inches long — and they've been carved into art for centuries.
The walrus possesses one of the most impressive baculums (penis bones) in the animal kingdom, measuring up to 22 inches (56 cm) long. This bone, found in most mammals but notably absent in humans, provides rigidity during mating.
The walrus baculum is so large and distinctive that it has cultural significance among Arctic peoples:
Oosik Carvings In Alaska and other Arctic regions, walrus baculums are carved into decorative items called "oosik" (an Inuit word). These polished bones are sold as: - Walking canes - Knife handles - Decorative sculptures - Collectibles
A single walrus baculum can sell for hundreds of dollars. The practice dates back centuries, though modern regulations govern their sale.
Why So Large? Scientists believe the massive baculum evolved due to: - Extended mating — copulation in water requires sustained rigidity - Sperm competition — larger baculums may help with sperm delivery - Cold water — maintaining an erection in frigid Arctic waters is challenging
The baculum shrinks when the animal dies and dries out, but even dried specimens are impressively large.
Walruses aren't alone in having baculums — most carnivores, primates, bats, and rodents have them. Humans are among the few mammals that lost this bone during evolution, possibly due to our shift to monogamy and shorter mating durations.
