Orthography Notes

  • saru さる becomes zaru ざる in this word because of a change in pronunciation called rendaku.


  • The old Japanese name for the Aye-Aye, yubizaru 指猿, literally "finger monkey," comes from the fact their middle finger is... weird. It's thin. And honestly creepy. I mean, seriously, it's really, really creepy. If you ever saw it from up close you may nope away faster than you can say "aye, Jesus, that's creepy!"


Scientific name: Daubentonia madagascariensis.
