12 Spider-Man Questions That Always Confused You

According to Peter Parker, his most important ability is his spider-sense - a sensation he experiences when he is in danger. We have heard the phrase, "My spider-sense is tingling!" so often, we don't question it anymore.

But the big question is this; can spiders instinctively detect danger? In the 2002 film, Spider-Man, a scientist explains that certain arachnids have "a set of reflexes with nerve conduction velocities so fast that some researchers believe it borders on precognition".

Although this explanation isn't true, arachnids can instinctively tell when they are in danger. At first, you'd assume spiders are pretty nifty at locating predators since they usually have eight eyes. However, spiders have terrible eyesight.

To get around, they relies on teeny-weeny hairs on their body called trichobothria. These hairs are so sensitive, some spiders can pick up on the movement of an object that is a 90-millionth of a millimetre thick. Each of its hairs work individually, allowing the creature to filter out certain sounds to focus on a noise from a potential predator.

This concept is shown perfectly in the beginning of Avengers: Infinity War when Peter Parker's arm-hair stands on end, alerting him of a crisis in the city.
