So the spider pictured has only 7 legs, even though spiders have 8 legs. This guy has obviously lost one–who knows how–but thankfully, spiders can regrow lost legs. The next time he molts, he will likely have 8 legs again.
As for the two leg-like-looking things at the front of the body–these are called pedipalps. All spiders have them, just as insects have a pair of antenna. Pedipalps are sensory organs and also used to manipulate prey. In mature males, the palps are enlarged like in this photo–not for boxing! but for storing their sperm. When they find a receptive female, they will transfer sperm to her through these pedipalps. Talk about an odd way to have sex!
