Island Sanctuary Could Save Sex-Crazed Northern Quoll

northern quoll

Life is tough if you’re a northern quoll (Dasyurus hallucatus). These rare, cat-sized Australian marsupials don’t have very long life spans—especially males, which tend to die after their first mating experience when less than a year old. You see, all female quolls go into heat at the same time, and it drives the males a [...]

Plenty of Pheromones in the Sea

As we sat in my car outside a silent movie theater in Los Angeles, my friend anxiously opened a plastic bag containing a white T-shirt she’d slept in for the past three nights. “Does it smell like me?” she asked nervously, gesturing the open end toward my face. I stuck my nose into the bag [...]

Why might a female zebra finch cheat on her partner?

Zebra finches are birds which, once they’ve found that special someone, will tend to stick with them. They are what is called ‘socially monogamous’, meaning they form pairs to mate and raise offspring over multiple breeding seasons, but with the occasional sneaky mating with the next door neighbour. Males court females by singing to them, [...]

50 Shades of Sea Slug Sex: It’s Stranger Than You Think

sea slug sex traumatic mating female

Two-part barbed penises, a physical struggle and 20 minutes of penetration. That’s how some sea slugs do it. But the real shocker is that, for one species at least, those in the female role seem to engage in these bizarre, violent sexual encounters more often than might be biologically necessary. Nothing about sea-slug sex sounds [...]

Whales can boom their songs across thousands of kilometers of ocean, and elephants’ low-frequency calls can be heard by other pachyderms several kilometers away. But when body size is taken into consideration, these mammoth mammals produce but a relative whisper compared with other animals—especially one odd arthropod. The water boatman (Micronecta scholtzi), a 2.3-millimeter-long insect, [...]

male finches can stress out females if incompatible

Whether they are finding love in a flock or a lab, female Gouldian finches (Erythrura gouldiae) know what they’re looking for: a fit male with head feathers that match their own. And the females that don’t end up with a desirable mate are slower to lay eggs and wind up more physiologically stressed, according to [...]

Firefly,bioluminescence,mating

For many, the warm glow of fireflies in the night air is a sure sign that summer has arrived. After dark, these bioluminescent beetles are generally visible only when they emit flashes of yellow, green or pale red from their lower abdomen as part of their mating ritual.

The grandmother factor: Why do only humans and whales live long past menopause?

killer whales live past menopause like humans do

Most mammals don’t live long past their reproductive years, failing to serve much evolutionary purpose after they can stop passing on their genes to offspring. Only three long-lived social mammalian species are known break that mold. Killer whales (Orcinus orca), pilot whales (Globicephala macrorhynchus) and humans (as well as possibly some other great apes) all [...]
