You're not wrong, though antipodes tends to pluralise antipode, rather than antipus! That said, wikipedia mentions antipus or antipous may have been correct before the 16th century, and antipode is likely a sort of reverse de-pluralisation. I can't say I'm familiar with many of the other -podes words: https://www.merriam-webster.com/wordfinder/classic/ends/all/-1/podes/1 https://www.merriam-webster.com/wordfinder/classic/ends/all/... They seem largely to be part of scientific species names. 'pods' is more natural feeling. Tripods, bipods, gastropods, cephalopods!
