The image above, found in Arcturus' Children’s Bible: Illustrated Stories from the Old and New Testaments, shows what at first looks to be a pretty standard depiction of animals boarding Noah's ark two-by-two.

But, due to sexual dimorphism, adult female lions are unable to grow manes, so that's definitely two dude lions you are looking at being loaded on for sexual purposes.

I doubt this was a conscious decision snuck in by the illustrator but it's a pleasing error all the same.

Children are at least getting an authentic depiction of the variety of life. A report in Pink News points out that wildlife experts discovered last year that gay bears enjoy oral sex, with "the first observations of long-term, recurrent fellatio in captive brown bears kept in proper conditions" being recorded by the Polish Academy of Sciences Department of Wildlife Conservation.

Kent zoo, meanwhile, has a gay penguin couple, which it claims make better parents than many of the straight ones.
