Stopped reading after the bold headline and first paragraph were exactly the same.
I hate it when articles do that.

I'm so lazy they will perceive me as inanimate. I knew my lack of exercise, or movement in general, would pay off.

Completely unsurprising discovery

/Though it is important to dot the i's in science even when it is obvious.

I love those suckers. No matter how big you are or how small they are, they raise up their front two legs in a "Come at me, bro!" attitude and it cracks me up. They are the only spiders I won't kill immediately out of instinct.

/brown cellar spiders are cool too

Along with preying mantises, they are among the only insects I've seen display non food-driven curiosity. They both have good eyesight, and will track your approach. They both know you are WAY too large to be a potential food source, are both fast enough to escape, and will both often hang around and climb onto a presented finger to explore what you are.

I lived on the top story of an apartment building back in my 20's. The outside walls were covered in these little guys, and would often get into the apartment. My cat at the time loved chasing the little guys because of their jumping ability - was always funny to watch because the spiders usually got away, and the cat was like 'WTF was that thing?!'

Yup. I dig praying mantises. One of the best bugs to have in a garden.

Barking spiders.

I think the person who make that claim about invertebrates has not met ants, carpenter bee, octopues, or... I think the quote was just a silly mistake and hould have been edited out of the news report.

I've a friend who's a population biologist. He had an experiment that showed that water striders made a variety of decisions about prey availability and predator danger. I think previously it had been thought that their tiny brains would all make identical decisions given the same data.

This opens up a whole new world.

I think I'll get a jumping spider as my new guard dog.

I'll call him . . . Phidippus Rex.

Came to say this. It's a strange, random, inaccurate "fact" someone plucked out of the air.

dryknife: Barking spiders.


Those awful barking spiders infested every campsite my scout troop went to. It's like they were all following my scoutmaster around. So many great scouting memories marred by unending waves of barking spiders during mealtime, or inside your tent trying to sleep.

The spiders we're almost as bad as the guy's farting.

from the paper
https://doi.org/10.1371/journal.pbio.​3​001172
The spiders were collected in the wild, in the garden of Esapolis' living insect museum, Padua, Italy between June and August 2020. Only animals with a body length bigger than 7 mm were collected to guarantee the proper functioning of the methodology. Once caught, the spiders were maintained in clear plastic boxes measuring 80 × 65 × 155 mm and immediately fed a small Tenebrio molitor to ensure a shared level of satiation before the test. The day after capture, a magnet was fixed to the head of each subject to allow us to constrain the animal on top of the treadmill for the duration of the experiment (see next paragraph). Subjects were first constrained between a sponge and a latex film. The latter presented a hole in correspondence with the location of the spider's head. Here, a 1 × 1 × 1 mm neodymium magnet was applied using a UV activated resin. Each spider underwent its first test between 1 and 3 days after receiving the magnet. At the end of the full experiment, each spider was again constrained under the latex film to remove the magnet. Spiders were then freed in the same place they were captured. Magnets did not appear to negatively affect the animals during the short period in which they were housed in the lab, and spiders that had the magnet removed appeared to move and behave normally.

Tenebrio molitor

Just wait until the farting spiders show up.....

Jumping spiders like to chase lasers, so don't get too excited...

Tiny jumping spiders are cute.
I like when one shows up for a visit.

Personnel working with SCP-1470 must report for psychological screening on a weekly basis, for a period no less than a year after exposure.

The hubris of the headline is insane.

We know invertebrates can distinguish between inanimate objects and living things at least most of the time based on their behavior.  Mosquitoes don't bite rocks, ffs.

Those 60 spiders formed a support group after the fact to deal with the PTSD from being functionally abducted by aliens who probed them and made them do weird tests.
