Our Sexual Nature exhibition peeps out of its gallery shell and darts onto the streets in August, with the help of the Q20 Theatre group's musical Snail Courtship Show on the South Bank.

Snail courtship is one of the many weird and wonderful examples of animal mating rituals that are currently on display in our Sexual Nature exhibition.

'The courtship ritual of the snail can be an unusual affair,' explains the exhibition's Interpretation Developer Tate Greenhalgh. ‘Roman snails shoot darts at one another in s&m-style foreplay. These darts stimulate the partners and aid fertilisation.’

Incidentally, Roman snails (right) - so called because it is believed that they were introduced into the UK by the Romans - are now an endangered species and have legal protection from collection, killing and trade here.

The live snail show performance at South Bank combines music, theatre and science to tell its sticky love story, and is an example of how the Museum is bringing the science of its exhibitions to life. Each performance runs for about 20 minutes.

At the show, lucky onlookers will get the chance to grab an exclusive 2-for-1 deal on tickets to the Sexual Nature exhibition.
