Spider-Man's powers and equipment

The fictional Marvel Comics superhero Spider-Man, who debuted in 1962, is well known for his unique superhuman abilities as depicted in the comics and other media. He receives most of his powers when he is bitten by a radioactive common house spider. He uses his technical skill to develop equipment and weapons to complement his powers, and wears a number of costumes, many of which have special properties.

When Peter Parker was bitten by an irradiated spider, radioactive mutagenic enzymes in the spider's venom quickly caused numerous body-wide changes. Immediately after the bite, he was granted his original powers: primarily superhuman strength, reflexes, and balance; the ability to cling tenaciously to most surfaces; and a subconscious ability to sense everything in his surroundings, which he called a "spider-sense".

Several biologists on the History Channel's Spider-Man Tech special stated the effect of a radioactive spider bite (if any) would not be nearly enough to cause a mutation in a human body. However, they said the use of "genetically engineered" spiders from the live-action movie and the Ultimate continuity was more plausible. Instead of radioactive venom, the bite would have to carry a powerful retrovirus (similar to HIV) that would spread through the body by taking over neighboring cells and actually becoming ingrained in the person's DNA. They illustrated this by showing the results of an experiment where glow genes from deep sea jellyfish were introduced into the embryos of lab mice. The resulting mice were born with the glow gene as a part of their own DNA and glowed light green whenever an ultraviolet light was shined on them.
