Birds do it, bees do it. Even female jumping spiders do it — dangerously. Check out ten ways animals get do it in the wild.
Boo! Halloween is a time for trickery, treats and fright. Some members of the human species transform themselves into devils, witches and ghouls. But if you’re looking for something completely different, and completely scary, let nature be your guide.
The arrival of a jumping spider sends most moths into a flutter trying to escape the predator’s lethal pounce.
Not so for metalmark moths in the genus Brenthia. These moths stand their ground with hind wings flared and forewings held above the body at a slight angle.
Like the comic book hero Spider-Man, who shoots webs from his wrists to swing through the city, real-life tarantulas spin silk from their feet to walk on slippery surfaces, according to a new study.
“To my knowledge, no other animals are using silk for locomotion,” said Stanislav Gorb, a biologist at the Max Planck Institute for Metals Research in Stuttgart, Germany.
For male Australian redback spiders, life is about sex and death. If they are lucky, the former is part of the latter—female redbacks eat their male mates during copulation.
But death comes first for 83 percent of the males, according to research.
In Hawaiian rain forests, scientists have discovered caterpillars with a taste for escargot: They trap snails on leaves using silk webbing and then eat them alive.
These are the first caterpillars known to eat snails or mollusks of any kind, an evolutionary adaptation likely enabled by the island chain’s isolation. The insects are also the first caterpillars known to use silk to ensnare prey in a spiderlike fashion.
“Aaaaaaaahhhh!!!!!” The mere sight of a snake or spider strikes terror in the hearts of millions of people.
A new study suggests that such fear has been shaped by evolution, stretching back to a time when early mammals had to survive and breed in an environment dominated by reptiles, some of which were deadly.
