Some slugs have huge blue-tinted penis and upside-down reproductive acrobatics.
Welcome to the strange, sticky and sensational world of slug sex.
If you come across this weird sight, you’d actually be witnessing is a mating ritual of a pair of amorous leopard slugs.
And the large blue tubes that grow out of the right side of the slugs’ heads are their immense penises, which can expand to the length of its entire body.
Terrestrial slugs are hermaphrodites – so by wrapping their penises around one another, they can fertilise each other’s eggs.
But most important, watching slugs making love is beautiful, it takes a long time and it’s kind of hypnotic and elegant.
