Researchers in Australia recently discovered a new species of demon catshark – a dusky deepwater shark with striking white eyes – by following a trail of some odd-looking eggs. Years ago, Brett Human, then a volunteer at the Western Australian Museum, came across an odd, yolk-yellow shark egg in the museum’s collection that had deep T-shaped ridges. Female catsharks incubate the eggs in their bodies for a while before sticking them to the sea floor, where they can take many months to hatch ...read more
Wild honeyguide birds and humans have hunted for honey together in Africa for centuries, if not longer. In some parts of the continent, the process starts when a hunter makes a loud, trilling “brr-hm” sound to attract the dull brown birds. They hop from tree to tree and chatter eagerly as they lead the honey hunter to a beehive in a baobab or other tree. After the human has looted the honey, the honeyguide dines on the beeswax left behind.A new study has found evidence that the famously reso ...read more
We’ve known about the colossal squid for nearly 150 years. Zoologist Japetus Steenstrup first reported on the species in 1857 after reading reports of it washing up on ocean shores. But there’s still a lot that we don’t know about it because it’s so hard to study. Its reproductive patterns, mating and hunting patterns are still largely unknown because we hardly ever see it in action. Nonetheless, ever since Twenty Thousand Leagues Under the Seas, we’ve been captivated by this supersiz ...read more
In the realm of insects, where the buzz of translucent wings and the patter of tiny feet reign, something troubling is unfolding: these small animals are quickly vanishing from the world. But how do scientists detect insects’ often silent disappearances? Because they’re tiny and often well hidden, detecting and preventing extinctions is no easy feat, explains Eliza Grames, a postdoctoral researcher at University of Nevada, Reno. “There are so many different things contributing to insect d ...read more
As Antarctica plunges deeper and deeper into winter at this time of year, the frigid continent’s surrounding lid of floating sea ice should be expanding rapidly. But this year, sea ice has been growing at an agonizingly sluggish pace that has been setting records day after day. “In the midst of its winter growth phase, Antarctic sea ice has reached a record smashing-low extent for this time of year,” according to the National Oceanic and Atmospheric Administration. “Sea ice extent is app ...read more
