what spider is spider man based on

According to the sources, the spider that bit Peter Parker and gave him his powers is identified differently in various media. In the original comic book, the spider is simply described as a "radioactive spider". However, in The Amazing Spider-Man 2 movie, the spider is identified as Araneus Oscorpeus. The Marvel fandom wiki lists its species as an unidentified Latrodectus, i.e. a black widow spider. Additionally, in a recent comic book series, the spider is given the name "Emil". Therefore, there is no one definitive answer to what spider Spider-Man is based on, as it varies depending on the source.
