"The butterfly and the ape."

Translation: Η πεταλούδα και ο πίθηκος.

Now we know why they called it “Australopithecus”.

What is the difference between ‘ο πίθηκος’ and ’το πιθήκι’?

[troll1995]

Πιθήκι is more likely used as an insult and not to describe the animal. Πχ Κάνει σαν πιθήκι = He is acting like a monkey! If used with the diminuitive (το πιθηκάκι) it is used to talk about the baby monkeys.

μαϊμού is not possible?

Looks like you haven't read the tips for the second skill (https://www.duolingo.com/skill/el/Basics-1/tips-and-notes) and are unwilling to google it too... ;)

[jsclingman]

Thanks! Yeah, it's just that I know that there's probably someone on these discussions who's willing to help me. I've observed that the Tips and Notes don't always contain the answers to my questions. :)

Apes are not monkeys and monkeys are not apes. This also applies to the Greek terms.
