Legs seem quite useful to spiders – after all, they have eight. But a recent Cornell University study found that a certain type of spider not only uses its legs to move, but also hears prey in the air – and turns it into lunch.

Research published in the journal Current Biology makes the spiders look like Marvel superheroes. It confirms that spiders use ankle sensitivity, or head sensors, to detect sounds, then trigger a tipping, ninja-like upside-down shot to attack non-insects. suspects in the air, put them in a net and then dine. “

The leprechaun spider, scientifically known as Deinopis spinosa, is a nocturnal creature found mainly in the southeastern United States.

Lead author Jay Stafstrom said the spiders in the study were “some of the greatest spiders on the planet”. They don’t do anything during the day, he said, but hide and wait for the sunset. Their web work is unusual – they create a “grid” shaped like a letter A, then create a “rectangular, translucent grid” that they hold with their front legs and use to actively hunting.

In addition to its unusual webs and multi-talented legs, these spiders are notable for their large eyes, which Stafstrom says is “the biggest eye of any spider.”
