    Higher temperatures could trigger an uptick in damselfly cannibalism

    A warmer climate could put some damselflies in distress, as others get bigger and hungrier.

    Because of differences in hatching time, nymphs — the immature form of the insects — vary in size. Sometimes when ponds are overcrowded, other food options are scarce or size differences are significant, bigger, older nymphs nosh on the little nymphs. While temperature doesn’t typically affect...

    Watch male cuttlefish fight over a female in the wild

    View the video

    The Bro Code apparently does not exist among wild cuttlefish. The first field video of male European cuttlefish (Sepia officinalis) getting physical over a female shows that they are not above stealing another guy’s girl.

    Cuttlefish, cephalopods known for their ability to alter their skin color, have complex and competitive courtship rituals. While scientists have...

    Seabirds use preening to decide how to divvy up parenting duties

    Seabirds called common murres appear to use preening as a way to negotiate whose turn it is to watch their chick and who must find food. And when one parent is feeling foul, irregularities in this grooming ritual may send the other a signal that all is not well, researchers report in the July issue of The Auk: Ornithological Advances.

    “The fascinating part of this study is the inference...

    Hawk moths convert nectar into antioxidants

    Hawk moths have a sweet solution to muscle damage.

    Manduca sexta moths dine solely on nectar, but the sugary liquid does more than fuel their bodies. The insects convert some of the sugars into antioxidants that protect the moths’ hardworking muscles, researchers report in the Feb. 17 Science.

    When animals expend a lot of energy, like hawk moths do as they rapidly beat their wings...

    New worm-snail is a super slimer

    A new species of worm-snail is rather snotty. Thylacodes vandyensis shoots out strands of mucus that tangle together, building a spiderweb-like trap for plankton and other floating snacks, researchers report April 5 in PeerJ.

    Other worm-snails use this hunting technique, but T. vandyensis stands out because of the “copious amounts of mucus” it ejects, says coauthor Rüdiger Bieler. This...

    Volcanic eruptions nearly snuffed out Gentoo penguin colony

    Penguins have been pooping on Ardley Island off the coast of the Antarctic Peninsula for a long, long time. The population there is one of the biggest and oldest Gentoo penguin (Pygoscelis papua) colonies. But evidence from ancient excrement suggests that these animals didn’t always flourish.

    The Gentoo colony on Ardley Island continues to grow in comparison to other Antarctic penguin...

    First fluorescent frogs might see each others’ glow

    Could fluorescence matter to a frog? Carlos Taboada wondered. They don’t have bedroom black lights, but their glow may still be about the night moves.

    Taboada’s question is new to herpetology. No one had shown fluorescence in amphibians, or in any land vertebrate except parrots, until he and colleagues recently tested South American polka dot tree frogs. Under white light, male and...

    Tool use in sea otters doesn't run in the family

    Aside from being adorable, sea otters and Indo-Pacific bottlenose dolphins share an ecological feat: Both species use tools. Otters crack open snails with rocks, and dolphins carry cone-shaped sponges to protect their snouts while scavenging for rock dwelling fish.

    Researchers have linked tool use in dolphins to a set of differences in mitochondrial DNA — which passes from mother to...

    A king snake’s strength is in its squeeze

    It’s not the size of a snake’s muscles that matter, but how it uses them. King snakes can defeat larger snakes in a wrestling match to the death because of how they coil around their prey, researchers report March 15 in the Journal of Experimental Biology.

    King snakes wrap around their food and squeeze with about twice as much pressure as rat snakes do, says David Penning, a functional...
