Sea creatures with eight arms covered in suction cups and a soft body, or pilots in Navy slang.
From squid (origin uncertain, possibly from English dialect or imitative of the creature's shape). The Navy slang meaning 'sailor' emerged in the 1900s, possibly from squid's boneless appearance resembling a new recruit.
Squid brains are distributed throughout their eight arms—each arm can solve problems independently—which means they're solving the same processing problem that humans solve by centralizing intelligence in one brain in a completely alien way.
