Forget his n’ hers watches this Valentine’s Day: A species of lemur prefers a set of matching scents. In a move that can only make master perfumers green with envy, pairs of Coquerel’s sifakas (Propithecus coquereli) that have mated and produced offspring alter their natural scents to smell alike. Primatologists at the Duke Lemur Center in Durham,...

Finding true love is difficult no matter what species you were born into—but at least humans don’t have to worry about being eaten on a first date. Black widow spider and scorpion females famously kill and sometimes eat males after sex. Of course, not all animal courtship is risky or dominated by females, “but in the science...

For some lovebirds in the animal kingdom, every day is Valentine’s Day. But how do mates win each other over? A little flirting can go a long way … and frankly, it’s a heck of a bonding agent with a long-term partner, too. See if some of these amorous animals have any tips you can...

Forget Miley Cyrus: When it comes to twerking, spiders can save their lives by shaking their booties, a new study says. Scientists have found that male black widows move their bodies in a certain way to let females know of their presence—and avoid becoming their next meal. (Also see “Surprise! Male Spiders Eat Females, Too.”)...

By Bradley Balukjian Thousands of feet under the sea, bone worms give new meaning to the song “It’s Raining Men.” These frilly pink creatures live on whale carcasses in harems that make free lovers of the 1960s look tame—up to 607 males cohabitating with a single female. That’s only possible space-wise because the males are...

By James Owen The only praying mantis native to New Zealand has developed a fatal attraction for a cannibal invader whose females devour its mates after sex, scientists report. Males of the New Zealand mantis (Orthodera novaezealandiae) are being seduced into serving themselves up as meals to females of the springbok mantis (Miomantis caffra), a...

Move over, Chanel No. 5. You’ve got a new competitor: The scent of bile is driving female sea lampreys crazy, a new study says. Bile wasn’t always an alluring scent—not even to sea lampreys, a type of parasitic fish. Millions of years ago it started out as a digestive aid, breaking down the fats in lampreys’...

Ancient bear penises offer the first hard evidence of how an extinct species of bear lived and mated, a new study says. Indarctos arctoides, which was about the size of today’s brown bear, roamed what is now France, Spain, and Turkey about 10 to 4.5 million years ago. Like most bears and many mammals, the...

By systematically combing through 90 years of breeding records from the San Diego Zoo, scientists discovered mammals can “choose” the sex of their offspring, a new study says. Tracing zoo birth records through three generations, the researchers found evidence for a decades-old theory of evolutionary biology: Mammals rely on some unknown physiological mechanism to manipulate the...

Female guppies (Poecilia reticulata) sometimes bring a little extra baggage to a relationship—in the form of a dead male’s sperm. A new study shows that one in four wild guppies in Trinidad and Tobago are fathered by the sperm of dead males. Some of these sperm have been stored for long enough that these males...
