Might as well jump. Their teaching methods were successful only after a long period of trial and error. The researchers had to be very careful to entice the spider to start learning, which was the hardest thing to figure out. The learning was done in a controlled environment using high-speed cameras and 3D CT scans, which allowed researchers to analyze the movements of the spider more closely.
After doing this, they physically moved the spider from one platform to another until it was conditioned to make the jump itself. Eventually, the spider learned how to do it on its own. They also used a gentle tool to encourage the spider to make the jump, which proved to be unsuccessful at first.
However, after some time, the spider learned how to jump with the gentle tool. And after a while, the spider started jumping on demand without the tool.
Kim, as the jumping spider was called, was now able to jump from one platform to another on-demand. This means that your job will be tougher from the start, although many owners have tried teaching their spiders to do different things. The new findings, published in Scientific Reports on Tuesday , provide a more detailed look at the jumping mechanism by which this species and others make extraordinarily long and precise leaps.
These types of jumps, traversing about 30 millimeters, were faster and prioritized speed and accuracy over other requirements. Meanwhile, longer jumps up to 60 millimeters in distance used steeper takeoff angles to optimize flight time and allow the spider to travel a greater distance, but also minimized the amount of energy exerted. Jumping spiders possess an incredibly sharp sense of vision compared to other arachnids and arthropods, with four large eyes in front and four more smaller ones on the top of the head.
This vision likely allows the spider to size up the distance and determine the proper timing and angle needed for the big or small leap. The researchers bought several regal jumping spiders from the local pet story in hopes of training them, but only the milligram, millimeter-long little bugger named Kim was willing to acquiesce to these demands.
