Five years ago a bottlenose dolphin strayed far from his usual habitat and ended up in the chilly waters off the Danish coast. He hung around, the locals named him Delle, and marine biologists at the University of Southern Denmark began studying the 17-year-old loner.
For weeks, bears in eastern Russia’s Amur region were having a hard time bedding down for the winter, as warm weather has kept the region unfit for hibernation. In a normal year, the bears will tuck in by the end of October, but the temperature didn’t drop until this week, so it’s time to say goodnight at last.
Researchers spent many hours watching and filming domestic cats in a Los Angeles cat cafe, and they determined that the felines can conjure nearly 300 facial expressions. The research is published in the journal Behavioural Processes.
Since 2007, marine biologists and interested amateurs have been observing a curious behavior of humpback whales called “kelping,” in which the giant cetaceans seem to be playing with seaweed. Now researchers from Griffiths University in Australia have looked into the phenomenon; their study appears in the Journal of Marine Science and Engineering.
Orcas – killer whales – are attacking small boats off the Iberian coast in Europe. There's been at least three apparently coordinated (!) attacks in recent weeks, and scientists believe the aggressive behavior is being taught to, or at least copied by, other pods.
There are 66 known emperor penguin colonies in Antarctica. The most recently discovered group, about 1000 adults with chicks on the West Antarctic coast, gave away their position to satellite cameras — with their guano.
An enduring and endearing staple of nature shows is the monogamous penguin. The idea that these tuxedo-clad flightless birds mate for life without the occasional affaire de coeur is adorable, but is it true?
Male mice are freaked out by bananas, and now we know why. Researchers at McGill University in Montreal discovered the fruit fear while analyzing spiking stress hormones in male mice when they are near pregnant or lactating females. The boys are triggered by a compound in the females’ urine called n-pentyl acetate, which also happens to be the compound that gives bananas their smell!
When an octopus mom’s eggs are close to hatching, she will start acting a little bit nuts. She may stop eating, tear at her own flesh, beat herself against a rock; and if she does eat, the meal might be pieces of her own arms. The gruesome self-flagellation continues until death.
