Male Darwin's Bark Spiders, who are 14 times smaller than the gigantic females, routinely salivate onto female arachnid genitalia, pre-, during, and post-copulation.
A dinosaur species known Protoceratops andrewsi sported an ornamental head appendage called a frill that was likely used to attract suitable mates and helped to assert social dominance.
It's no secret that the ladies love a deep voice. Barry White's rise to fame is proof of that. However, the Prince of Pillow Talk may not be as popular with deer, especially bucks during mating season.
For nightingales, nothing is hotter than good fathering skills. That's at least what bird experts now think after extensively studying the songs of male nightingales. Traditionally, it was thought that these songs simply told listening females about a male's health and other desirable traits. Now, they think the 'lyrics' are actually about how good a dad he'd be.
For as long as it has been in society's crosshairs, homosexuality has been part of a very simple debate: is it natural or is it a choice? The question of whether it was helpful to a species was never considered; after all, do we question whether it's better for humanity to boast a specific eye color or personality? Now however, a new study has revealed that the trait can be very helpful to a species, and you won't believe how.
Sleek and graceful, frisky and mischievous - humans have long drawn obvious parallels between feline characteristics and 'sexy' behavior. Now, researchers have determined that one species of spider may have also taken some cues from the kitty-cat playbook, apparently purring like pleased Persians in order to attract a mate.
The longhorned beetle was long thought to be the cologne connoisseur of the insect world, selecting mates based on smell alone. However, like a frat house drowning in Axe body spray, sometimes all the males in a region smell the same. So how do lady longhorns know who's 'Mr. Right?' According to a new study, timing is everything.
When you hear "getting it on like animals" you probably think animals are 'doing the deed' all the time and whenever they please. But when you really think about it, how could they? With predators always looking to make an easy meal of any pair that's... distracted, it may be hard to get some alone time. That's why one frog in Brazil builds secret underwater chambers just for this purpose.
The big red bottom of female baboons has always been an iconic image for the species. However, even if they knew the lyrics, no male baboon would ever be caught enthusiastically singing "Baby Got Back." New research has revealed that baboons don't actually care what sized backside "baby" has at all - a huge surprise for animal behaviorists everywhere.
You might not hear it, but mice are actually practiced singers. In fact, male mice might actually rely opn their voices to grab a girls attention, not unlike many songbirds.
You've probably heard it on TV and social media. This is the "Age of the Big Butt," where society's concept of beauty is increasingly coinciding with sex appeal and a love for curves. A large-but-toned backside in particular is supposedly the new vogue (even if men have been staring at them for centuries). Now, researchers from The University of Texas (UT) at Austin explain that our fascination with the butt is being driven by evolution, and it may actually be all about the spine.
Silk has long been seen as a sexy fabric. Smooth and luxurious, it can drape a woman in all the right ways to catch a man's eye. However, human's aren't the only species that uses silk to catch a mate. New research has determined that the female wolf spider will improve her silk draglines when vying for the attention of a male, showing that spider courting isn't always a one-sided affair.
If Barry White were a horse, he'd be the stallion with ALL the mares he could handle. New research has revealed that while mares want their stallion strong, they likewise value a deep-throated whinny, and scientists think they know why.
The strange world of spider sex: it's a popular subject among researchers because, well, it will certainly keep you guessing. That's pretty much how things went recently for a team of scientists studying the Darwin's bark spider (Caerostris darwini), after discovering that males may be performing oral sex to keep females happy and - most importantly - not wondering what their mate might taste like.
It's no secret that for spiders and many other predator bugs, reproduction can quite literally involve courting death. The black widow, infamous as its own widow-maker, is one of the most iconic cannibal spiders around. Now a new study has revealed that male black widows have a fighting chance. They can smell if a female is hungry, helping them decide if courting her is worth the risk.
