It's a hard life being a male spider. Sex destroys your genitalia and then your partner will - most likely - eat you.
But, for those spiders who make it back to have another go (spiders are given two 'palps' with which to mate), half will remain monogamous and head back to the lady spider who made their first encounter so memorable, says new research published in BioMed Central's open access journal Frontiers In Zoology.
So far, so unlike humans.
But wait. In another twist of 'spiders aren't like humans' logic, the male is more likely to head back to the woman if she is... on the larger size (as bigger females tend to be more fertile).
In addition, the male spiders who preferred not to remain faithful preferred to 'trade up' to heavier females as second mates, says the report.
However, this is a risky mating strategy as there's a good chance another male spider will have already left their 'palp' inside that female, thereby forming a 'plug' to prevent such antics, researchers point out.
Although penguins dating scene starts off like a huge speed-dating event (all male and female penguins congregate in their thousands to the colony's breeding ground), when they find 'the one', they stick with them for years - sometimes throughout their life.
It's easy to mistake the gorgeous peacock bird as being female but in fact, the birds with the biggest plumage are indeed male. In a bid to attract a potential mate, the peacock flaunts his huge blue and green feathers in a flamboyant style, waddling from side to side.
The dung beetle sure knows how to treat a lady! The male shows off his strength by enthusiastically rolling a huge ball of dung during a romantic stroll. During his effort, the female will hitch a ride and the pair will go on to mate and hatch their eggs in the dung ball.
Like a scene from your local nightclub, male seadragons dance their way into their lady's heart by shimmying and shaking his body in a bid to seduce a mate. If the female is interested, she'll mirror his movement.
This cuddly bears take a less than subtle approach when they're looking for a mate! Koalas sing at the top of their voices in the hope his tuneless singsong will attract a lady.
This bird has a unique (and hilarious) technique when it comes to pulling another bird. As he puffs out his chest and wings, he breaks into an impressive wiggle as he circles his object of desire.
Female hedgehogs are stubborn things and like the male to try his very hardest to get her attention all while she plays hard-to-get. The poor male will casually pace around her (sometime for hours) until she decides whether she wants to give him a shot.
Lions are frisky mammals and mate around eight times a day. They don't have any fancy rituals and just get down to it!
Horrid mosquitos can actually be quite romantic when it comes to mating. After flapping its wings to attract his lady's attention, the bug then sings a 'love song' - which to use sounds like buzzing - and if the female is interested, she'll sing back to him. As they start singing together, they mirror each other's movement and break into a synchronised dance.
Who said chivalry was dead? Male elephants like to keep the romance alive with some playful flirting in a bid to woo his mate... the female repays the compliment by peeing in his face!
