Could be. In my language, we don't differentiate between monkeys and apes. (Like how in English you call any lightness of blue blue, but not any lightness of orange (darker: brown) or red (lighter: pink). Russian would call the blues, sinii and goluboi, as different as orange and brown are to us.) I couldn't tell you the difference in English, so I probably wouldn't have remembered if it was one or the other ...if I got the information in English in the first place
