That would be the plural using Greek rules: both platypus and octopus are from Greek, and do not (as is commonly assumed) use the Latin plurals platypi and octopi.
The correct English plural is either platypuses or the same word platypus (used as a group noun, like sheep or trout).
The pluralization of octopus as "octopi" is in fact, in its Latinate form, incorrect, as this would require it to be a second declension Latin word. Since its classification in Latin form is third declension, according to classical Latin grammar rules, the plural of octopus should be octopodes. In any case, the more commonly used plural of octopus is "octopuses" - which classicists regard as an incorrect oversimplification. Besides this, the plural of platypus cannot be universally agreed upon either - "platypuses", "platypus", and "platypi", as well as the grammatically correct plural "platypodes", are used with varying levels of popularity.
