Zoo administrators said the 3,450-pound walrus, one of only 17 walruses in U.S. zoos and aquariums, has two girlfriends but has yet to become a father. They said he is helping them to understand the species' biology.
"We really want to understand reproductive biology better not only to enhance breeding here, but also at facilities in North America and worldwide," zoo general curator Karen Goodrowe Beck said. "By studying the walruses here and changes in their bodies, it gives us a model to base studies on in the wild."
