Aside from humans, the only species recorded to have lifelong same-s.ᴇ x partnerships is male domestic sheep (BBC). Although many species display bis.ᴇ xual behavior, the following five species engage in same-s.ᴇ x female relationships.
Bonobos seem to enjoy same-s.ᴇ x female sᴛɪᴍᴜʟᴀᴛɪᴏɴ. In a 1995 Scietific American paper by Frans de Waal, he describes female bonobos rubbing their g̴e̴n̴i̴t̴a̴l̴s̴ together, “emitting grins and squeals that probably reflect ᴏʀɢᴀsᴍɪᴄ experiences” (BBC). Can’t say I blame them.
2. Japanese Macaques
Because female macaques exhibit more s.ᴇ xual positions than males, it’s believed lesbian macaques simply seek more s.ᴇ xual sᴛɪᴍᴜʟᴀᴛɪᴏɴ. (BBC)
3. Spotted Hyenas
As ᴍᴀᴛriarchs, female spotted hyenas dominate the male hyenas in the family structure, being larger in stature and physically more ᴀɢɢʀᴇssɪve (Kay E. Holekamp Lab) which also seems to result in female spotted hyenas mounting other females as dominant s.ᴇ xual acts.
4. Bottlenose Dolphins
S.ᴇ x is something animals use to their advantage, and it seems bottlenose dolphins aren’t any different from humans. Both females and males display bis.ᴇ xual behaviour to help them create strong social bonds within their pods.
5. Laysan Albatross
The Laysan Albatross population on Oahu, Hawaii contain 31% female couples as pairing parents. Female albatross ᴍᴀᴛᴇ with other females for the survival of their offspring; an endeavor that takes two parents to raise one chick per season. “They rear chicks, fathered by males that are already in a committed pair but which sneak ᴍᴀᴛings with one or both of the females” (BBC) And because Albatross have a tendency towards monogamy, once lesbian albatross ᴍᴀᴛᴇ, it’s for life.
