Welcome to the world of the spider, up close and personal as only the photographers and cinematographers of National Geographic can show it. The spiders and their webs are an ever-fascinating subject for those curious about nature, always providing a visual treat. Not all spiders weave the most familiar kind of web, which can catch houseflies and gnats. Some spin webs large enough to catch small birds, while others go fishing - diving into the water to catch their prey. The mating rituals are notoriously fraught with danger for the male. After fertilization, he becomes reproductively unnecessary and sometimes - lunch. A well-composed musical score adds to this enjoyable feature.
