How to say "fauna" in Japanese

• ファウナ
  nounThe katakana borrowing of 'fauna'; it denotes the animal life of a region or period and is used much as the English word is, particularly in scientific and academic contexts.
• 動物誌どうぶつし
  nounA fauna as a written work: a systematic treatise or survey of the animals of a region, found especially in scholarly titles; it does not refer to the animals themselves.
• 動物相どうぶつそう
  nounThe animal life characteristic of a particular region or period, treated as a whole; this is the usual term in biology, pairing with 植物相 as the counterpart of 'flora'.
• 動物群どうぶつぐん
  nounLiterally a group of animals: an assemblage of the animals of a place; it can also correspond to 'biota'. For 'fauna' as a region's animal life in general, 動物相 is usually the better choice.

Choose 「ファウナ」 as the direct loanword, 動物相 for the animal life of a region in scientific use, 動物誌 for a fauna as a written survey, and 動物群 for an animal assemblage or biota.
