Spiders can be fast. just a reminder of how one species - triangle weaver spider (Hyptiotes cavatus) does it.
It uses "external power amplification” to do the trick. “Basically, an animal uses an external device (in this case, the spider's web) to store energy, like a person storing energy in a bow with a pulled-back arrow. Once the energy is released, the spider is flung forward like a slingshot, greatly exceeding the speeds at which the arachnid could otherwise travel.”
Then it says how they did the trick:
"To study the critter, the scientists collected wild triangle weaver spiders, which are native to the United States and Canada, and brought them to the lab, where the spiders were housed in terrariums and filmed with high-speed videos as they hunted prey.
Daniel Maksuta, a doctoral student studying polymer science at the University of Akron in Ohio says. "It really works out too. [If] the prey is massive in comparison to the web and the spider, the web kind of just flings around it. So, that's how [the prey] gets all tangled up."
The maneuver is so fast, the spider can be hurled forward at accelerations of about 772 meters squared (2,535 feet/second squared).
Animals can do all kinds of tricks. For instance, the tiny crustaceans can live in the depths of the sea. And, frog choruses inspire wireless sensor networks.
Thus, biomimetrics or biomimicry or copying amazing design seen in nature has recently become a success.

According to evolutionary dogma, dino-age mammals were tiny creatures that hardly resembled anything we see today.
But fossils tell a very different kind of story.
In 2014, a paper on the discovery of three Jurassic squirrels (or at least animals that looked a lot like today’s squirrels) was published in the journal Nature.
While some researchers might hesitate to call them squirrels, the media used that very name, either with or without quotation marks. According to Sci-News:
“A group of paleontologists led by Dr Jin Meng of American Museum of Natural History has discovered three squirrel-like mammals that lived in what is now China during Jurassic, about 160 million years ago.”
If animals are “squirrel-like,” might they not actually be squirrels? The title of the article – Three Jurassic Squirrel Species Discovered in China – does suggest this.
Sci-News goes on to say,
“The three new species, named Shenshou lui, Xianshou linglong, and Xianshou songae, are described from six nearly complete 160-million-year-old fossils.
These animals were successful tree-dwellers, weighing between 30 and 300 grams.”
The fossils were extremely well preserved. Despite some minor differences with today’s specimens, they support the view that squirrels have been squirrels since time immemorial.
Some leading evolutionists have previously acknowledged that tree squirrels are living fossils. They should have even more reason to do so after this discovery.
Living fossils show that change of the Darwinian variety is rare in the animal kingdom.
Animals produce offspring after their kinds but do not change into other kinds. In other words, an important biological principle introduced in the Book of Genesis describes reality much better than the Darwinian story.
