They're all at it in this exhibition. But that's to be expected as Sexual Nature is a candid exploration of sex in the natural world.
From bonobos to bunnies, guppies to gorillas, hedgehogs to hyenas and pheasants to penis bones, there is virtually no animal sexual practice, appendage or orientation that doesn't get a look in at this extraordinary science show. Plants and humans feature too, although the emphasis is on the animal kingdom. And the amusing antics of Isabella Rossellini impersonating animals having sex in her Green Porno film series are a real treat.
Today, 11 February, the exhibition opened its doors to the public after a hectic week of VIP events, media previews and press coverage and as I write our first visitors are now getting a taste of this sensuous and beautifully designed gallery experience. The heady mix of specimens, exhibits, films and facts is guartanteed to leave them buzzing by the end of their visit. I feel sure many will be coming back for more.
Before you visit, get a taste of the exhibition in our highlights slideshow on the website.
The exhibition contains frank information and imagery about sex, so it's best to look at the Parents sample content guide on the website first if you're considering bringing kids. A similar brochure is also available in the gallery.
You can visit Sexual Nature in the evening at our After Hours monthly events and if you want to take things further, there are sex talks and sexuality debates coming up too at After Hours.
