Talking about primates in everyday language, often focusing on non-human primates like monkeys and apes.

サル is a broad term that covers both monkeys and apes in everyday language. 類人猿 specifically means 'apes' (hominoids) and is more technical. If you need to distinguish between monkeys and apes, use サル for monkeys and 類人猿 for apes, but in casual conversation, サル is often sufficient.
霊長類 is a formal, scientific term. In casual conversation, people usually just say サル. Use 霊長類 when discussing biology, evolution, or in academic settings.
