arm waving as a threat is usually accompanied by bared fangs and bluff charges towards the perceived threat, whereas curiosity is shown through more gentle arm and pedipalp movements, looking around, and a relaxed posture. ? jumping spider arachnophobia phidippus regius spiders asks venus.
The male peacock jumping spider must dance for his life. In order to woo a female and avoid being eaten, he performs an intricate dance using a brilliantly colored fan attached to his abdomen. If the female approves, he is allowed to mate. If not, he becomes her next meal.

This Sylvana jumping spider may look curious and intrigued, but it's probably not feeling fear. No, spiders cannot feel emotions analogous to those felt by humans.
By turning on lights, making noise and vibrations, cleaning up and moving around, we make it harder for spiders to catch insects to eat. Conversely, if we keep a messy living environment that attracts other insects, spiders will be very happy to live nearby.

At some times in a spider's life it is easy to tell whether it is a male or a female, but at other times it can be impossible. This is because the reproductive organs of a spider do not develop until the spider has reached maturity. Juvenile male and female spiders look almost exactly the same.
Spiders spin webs to protect their eggs or as a hunting tool, a small silk net that they throw over their prey. They can also use webs for transport, climbing to a high point and then release one or more sail-like strands of silk which get caught by the breeze and carries them away.
If your spider has clearly visible, comma-shaped thickenings at the end of its pedipalps, i.e. on its palps, it is 100% a male. If your spider has a clearly visible epigyne between its book lungs, i.e. on the underside of the spider, it is 100% a female.
Spiders don't have ears like we do, and many have poor eyesight. But they can sense vibrations, like those that happen when an unlucky insect touches their webs. And instead of eardrums, spiders hear using tiny, sensitive hairs that move in response to sounds.
In a new study published in the journal Proceedings of the National Academy of Sciences, researchers examined infrared footage of 30 baby jumping spiders (Evarcha arcuata) while they slept and ultimately found that they may, in fact, experience REM sleep.
