What is a Baculum?
The baculum is a unique bone found in the penis of most mammals. The bone aids in copulation when mates have only a brief encounter and need to perform quickly. The baculum is sometimes referred to as a "mountain man toothpick" and can be utilized as a coffee stirrer. The largest baculum in the mammal kingdom belongs to the walrus, whose baculum can reach a length of 30 inches!
This "package" includes bacula from a raccoon, mink, weasel, coyote, and beaver.
