Bug Girl has an article about spider sex, dressed up in a comparison with the movie version of Spider-Man (the original comic book hero has a different story). It’s full of PG-13 terms and may be disturbing to die-hard fans (but funny to the rest of us). The upshot is that male spiders have a very weird and complicated procedure for impregnating female spiders. You’ll never look at Peter Parker the same way again. You’ve been warned. -via Metafilter
