pig-tailed macaque
Refers specifically to the primate species Macaca nemestrina, also known as the southern pig-tailed macaque.
I saw a pig-tailed macaque at the zoo.
Kanji spelling is uncommon; the word is usually written in katakana.
Compound of 豚 (buta, 'pig') + 尾 (o, 'tail') + 猿 (saru, 'monkey'), referring to the animal's short, pig-like tail. The exact derivation is uncertain; the spelling is conventionally associated with the meaning.
