“The club of fellatio-loving animals just gained a new member: bears.
Scientists have observed a pair of male brown bears in captivity in Croatia that regularly engaged in oral sex over several years. While the creatures in this case study likely do it for pleasure, their fellatio habits might have started because they were forced to wean too early, the researchers suspect.
The two, unrelated male bears in the study were orphaned soon after they were born in 2003 and put in captivity at a sanctuary in Kuterevo, Croatia. Over the course of six years and 116 hours of observation time, scientists led by Agnieszka Sergiel, of the Polish Academy of Sciences’ Department of Wildlife Conservation, witnessed 28 acts of fellatio between the two male bears.”*
