Scientists are sexy. At least according to Business Insider. But do you really care about what the scientists look like when you can learn about actual sexy science? Male lions giving hickeys to females, female spiders cannibalising males during sex or antechinus mating themselves to death. This only brushes the surface of crazy animal sex. To discover the truly fascinating mating strategies we need to delve deeper. In fact, we need to jump into the big, blue sea.
Some of the most intriguing mating systems receive much less attention. Maybe because it usually involves expensive equipment just to get a peep at the animals under the surface. However, here is a world of disposable penises, traumatic insemination, asexual reproduction (no partner needed!), pregnant males, males with disproportionately large penises, aggressive competitions, die-hard romantics … the list is endless! So today I am here to spread the word about salty sex.
Let’s start with the inappropriately named sea slugs. These beautiful, brightly coloured molluscs can be found all over the world. Not only are these guys favourite subjects for underwater photographers, they also bring new meaning to the King Missile song, “Detachable Penis”. In other words, after mating the penis drops off. However, these lucky buggers can grow a brand new one in 24hrs. This little miracle can happen only three times. Luckily these critters have both male and female reproductive organs. So after all the penises are lost to the sea, they can continue mating as a female!
Stay tuned for the next installment of salty sex.
