Below you will find a few more examples from the exhibition, with information on where to obtain licence for use.

Two young male giraffes, Giraffa camelopardalis, mating by the roadside. Scientists have often turned a blind eye to animal homosexuality. In one study area where over 95 % of all sexual activity was between males, the researcher noted it as “sparring”, a form of ritual combat.
