Mating leopard slugs dangle from branches by a shared rope of their own slime with their penises hanging below. As hermaphrodites, these slugs inseminate each other during sex so, once the action starts, two penises are on display. And their penises are easily spotted: They’re electric blue and roughly the size of the slugs themselves. You just need to go look that one up,” says Willingham. You can see a video of the slugs in action here.Peter J Chenoweth; Steven Lorton (30 April 2014). Animal Andrology: Theories and Applications. CABI. ISBN 978-1-78064-316-8. Mukasa-Mugerwa, E.

( June 2013) ( Learn how and when to remove this template message) Birds have them, bees have them, even regular old fleas have them, but in the animal kingdom, no penis is exactly like the next. Across vastly different species and ecosystems, unique environmental pressures have allowed creatures of many species to evolve an array of shapes and sizes—from the electric blue penis of the leopard slug to the blue whale’s ten-foot phallus.
