Researchers in Ethiopia documented an unusual sexual bond between a bull and male donkey, including 51 mountings over two weeks.

The ungulates, dubbed Achille and Patroclo, chose each other repeatedly and showed affection before and after each rendezvous. Same-sex sexual encounters are common among animals of the same species, but less so between different ones

Patroclo and Achille’s interspecies affair sheds new light on social and sexual relations between animals, scientists say

The pair also display affectionate behaviors including licking, rubbing, and nuzzling.
