Space Pirates are pirates that cruise around space stealing cargo from ships like the Planet Express Ship. The pirates have four legs, some wooden, as well as three eyes, with patches over some. Fry and Leela succeeded in fending off two of their Pirate Ships although they lost Bender in the process.
Robot Space Pirates also exist, it is very likely that Space Pirates can originate from practically any species. Flags differ between groups of pirates.
Space Pirates may be similar to Space Banditos. The main difference being that Space Banditos use maracas.
