Plants & Animals

Plants & Animals 
動植物などの呼び方

As a speaker of any language, you know the names of many living things. This lesson will serve as the basis for learning those names in Japanese. 

Living Things 生物

All life, including mankind on the planet Earth is thought to have a common ancestor. This primitive life form is thought to have arisen at the same time if not shortly before the emergence of Earth’s oceans. From then, it would take nearly two billion years after the emergence of the oceans for single-cellular life to evolve into multi-cellular life. 

Even without being fully versed in biology, a trip to your local zoo, aquarium, or even a botanical garden will expose you to many of the taxonomical classifications used to classify life. 

生命“Life” as in the characteristic that separates the living from inanimate objects. Important derivatives include 生命体 (life-form), 原子生命体 (primitive life-form), and 生命力 (vitality/life force). 生命 may also figuratively mean one’s “life” as in “career.”
起源 “Origin” as in the “beginning/rise” of things, especially for things of considerable significance. 
人類“Mankind” but extends to all species of human, extant and extinct. 
惑星“Planets” as in the celestial objects that generally orbit around a star. This word may also mean “dark horse” as “surprise contender” in a figurative sense.
地球The planet Earth.
共通祖先A “common ancestor” is the last ancestor that two species once shared. The “last universal common ancestor” (全生物最終共通祖先) is the last ancestor that all extant life (現存する生物) shares. 
海洋The Sino-Japanese equivalent to 海 meaning “ocean,” it is a more fitting word to describe the oceans of early Earth as the Earth’s surface had less land surface. The opposite of “ocean” in this sense is 陸地.
誕生Although this word usually means “birth,” it may also refer to the emergence of new things and situations. 
生物・生き物These are the Sino-Japanese and native word respectively for “living thing/organism.” Any technical terms utilize the Sino-Japanese form such as in 生物学 (biology), 単細胞生物 (single-cellular organism) and 多細胞生物 (multi-cellular organism). 
進化“Evolution” as well as the word for “progress/improvement.” Derived words include 進化論 “the theory of evolution” and 進化形 “evolved form.” 
動物園A “zoo” is a facility (施設) where one can observe mostly land animals (陸上の動物), but there may still be some aquatic animals (水中の動物).
水族館Meaning “aquarium,” its Standard Japanese pronunciation is すいぞくかん, but you may also hear すいぞっかん.
植物園“Botanical garden.” Zoos and botanical gardens may be combined, in which case that would be a 動植物園.
分類学Taxonomy is a field in biology meant to categorize (分類する) living things via a hierarchy. Taking our species, humans (Homo Sapiens) as an example, our breakdown with what is called the Linnaean Hierarchy is as follows:
Linnaean Hierarchy
リンネ式階層分類 
Organism 生物 

Domain ドメイン ・Eukaryote 真核生物

Kingdom 界・Animalia 動物界

Phylum 門・Chordata 脊索動物門

Class 綱・Mammalia 哺乳類綱

Order 目・Primate 霊長目

Family 科・Hominidae ヒト科

Tribe 族・Hominini ヒト族

Genus 属・Homo ヒト属

Species 種・Homo Sapiens ホモ・サピエンス(ヒト

You may also be familiar with what is called a phylogenetic tree (系統樹) that connects all life together into a single diagram based on these classifications. 

Even with little knowledge of biology, most speakers of Japanese have a fairly good understanding of the broad terms that can be taken from taxonomy. For instance, people know most of the kingdoms of life (plants, animals, bacteria, fungi, etc.), and people generally know a large handful of classes (fishes, amphibians, etc.) and orders (rodentia = rodents) of animals. 

Everyday vs Technical Words
一般用語と専門用語との違い

English possesses everyday words such as “dog” and “cat” as well as Latin-based terms such as “canine/Canis” and “feline/Felidae” when categorizing organisms. 

Words like “canine/feline” refer to clades, which are organisms who share a common ancestor,” but a clade can refer to any converging of branches on the phylogenetic tree of life that is pertinent. Even though “canine” and “feline” are naturally associated groups (clades) which people often view as being parallel, the taxonomically correct nomenclatures “Canis” and “Felidae,” in fact, are not of the same hierarchy on the phylogenetic tree of life. “Canis” is a genus, whereas “Felidae” is a family. 

Japanese is parallel to English in its wording conventions. Consequently, Japanese has everyday words which derive from native vocabulary such as 鳥 and 魚 as well as technical words which derive from Sino-Japanese morphemes such as 鳥類 (clade)/鳥綱 (order) and 魚類 (clade)・魚綱 (order), demonstrating distinctions between “clades” and the more specific hierarchy on the tree of life. 

Common “Macro” Terms 
マクロ視点に基づいた一般的な用語

In everyday speech, words like “giraffe,” “dog,” “shark,” etc. relate to individual species, and although those terms are, in fact, the primary focus of this lesson, getting down the most important macro terms relating to kingdom, phylum, order, family, clade, etc. is especially helpful when deciding which words to focus on.

■Understanding “Clades” between English and Japanese:

It may seem tempting to equate ~類 with ~綱, but because ~類 equates to “clade” and “clade” is as big as is relevant, what ~類 relates to is contextual. Sometimes, this is problematic when English and Japanese speakers do not see eye-to-eye. For instance, in Japanese イヌ科 means “Canidae” which is the family of animals that includes dogs, wolves, foxes, etc. However, the word イヌ itself historically only refers to “dogs,” with wolves occasionally being referred to as ヤマイヌ. When イヌ類 was coined, the clade of “canines” it referred to did not include other related animals in the same genus such as coyotes, foxes, or even tanuki. As all dogs do share a common ancestor, this “clade” is just as valid, but it is not the same “clade” as is meant by the English word “canine.” Instead, “canine” and “Canis” are both translated into Japanese as イヌ属. Contrastingly to this, “feline” and “Felidae” do happen to correspond neatly with ネコ類 and ネコ科 respectively. As for イヌ科, it includes various other genera which have since gone extinct. 

This logic also applies to how the word 人類 is understood. People for religious beliefs may only apply this word to our species Homo Sapiens, but in scientific terms, it is equivalent to ヒト属, the genus that includes all ‘human’ species. 

What say about terms such as “arthropod” which relates to a phylum but is much larger in scope than the order of “insects”? In such a scenario, 昆虫類 has already come to be equivalent to 昆虫綱, so it cannot be misconstrued as something higher up on the tree of life. Conjecturally, both 哺乳類 (mammals) and 霊長類 (primates) exist despite being related, but this further shows how the use of ~類 boils down to natural and meaningful associations that people immediately recognize. Once something is as large as a “phylum,” it becomes more logical to simply refer to them as 〇〇動物/〇〇植物.

※類人猿 is not a proper term in taxonomy and is instead replaced by ヒト科 (Hominidae).

■Categorizing Things By What They Eat

Although such categorization is not helpful when talking about living things which are not animals, the terms “carnivore,” “omnivore,” and “herbivore” are wildly used, which in Japanese are 肉食動物, 雑食動物, and 草食動物 respectively. 

Spelling 
動植物の表記

Spelling plants, animals, etc. is notably difficult even for native speakers. Given that Kanji represent individual Chinese morphemes (units of meaning), it is only natural that most plants and animals have their own separate or pair of Kanji. 

While certain Kanji such as 犬 (dog), 猫 (cat), 鳥 (bird), etc. already recognizable even to beginners, others such as 熊 (bear), 鯨 (whale), 蛇 (snake), etc. are out of reach at the intermediate level. Even well-versed, native readers struggle to always recognize high-level spellings such as 山梔子(くちなし)meaning “gardenia.”

The first thing to keep in mind is that not all plants and animals are found natively in Japan, or China for that matter. As obvious as this might seem, this fact is crucial to guessing whether something will have a Kanji spelling in Japanese. Chinese, on the other hand, is solely written in Kanji, and in many instances, translations as well as Ateji spellings unique to Chinese have been coined for non-native things to them. Some of those inspirations have been carried over into Japanese. 

All being said, spellings can be categorized as following under one of the following three scenarios:

1. The ‘basic’ native/Sino-Japanese vocabulary for plants/animals are all potentially written in Kanji, and these spellings are easily recognizable by any reader. 
Exs. 馬 (horse) (bird), 鮫 (shark), etc.

2. Obscure spellings coined when Japan was catching up with the rest of the world with its vocabulary to describe non-native things.
Exs. 狩猟豹 (cheetah), 亜米利加豹 (jaguar), etc.

3. Imported spellings from Modern Chinese (coined for the same reason as Scenario 2), by writer’s discretion. 

Exs.  小袋鼠 (wallaby), 更格廬 (kangaroo), etc.

To simplify everything in biology settings, all species are written in Katakana. When average people do not know or do not wish to use the Kanji spelling of a particular plant/animal, opting to either Katakana or Hiragana is permissible.

Given everything mentioned thus far, when parsing through the significant amount of information shown in the charts, spellings in bold are of Category 1 from above, but advanced spellings in this category beyond the average collegiate level may not be in bold. However, just because a Kanji spelling is not in bold does not necessarily mean the word is not important. This may also hold true for indigenous animals in Japan being important in Japanese even if the English equivalent term is rare because said animal is not common or native to English-speaking countries.

The Animal Kingdom (動物界)

Now that we have learned about how life is categorized, it is time to learn about all the animal words that are relevant to you as a Japanese learner. In doing so, we will be covering mammals, birds, reptiles, amphibians, insects, and sea creatures. The last category lumps many different kinds of animals not directly related to each other for the sake of simplicity. 

Out of fairness to learners from all over the world, animals particular to specific parts of the world are also listed.

Reading Notes: Some Kanji spellings are direct imports from Chinese and, thus, may have alternative readings, but these readings rarely see the light of day in the spoken language. On occasion, native names have been coined for animals non-native to Japan. This, though, allows a reader to potentially read those new coined Kanji spellings with the foreign word which entered the language first as Ateji. Examples of these scenarios include the following:

1. 熊猫 = シューマオ (from Modern Chinese reading)・くまねこ (new KUN reading derived from Chinese spelling).
2. 狩猟豹 = しゅりょうひょう.
3. コアラ = 袋熊(ふくろぐま)・子守熊(こもりぐま).
4. 猩々 = しょうじょう.
5.  大猩々 = だいしょうじょう.
6.  The reading りぎゅう of 犛牛 is the Sino-Japanese word for “yak,” but there is also another Sino-Japanese word, ぼうぎゅう, which can be spelled as 旄牛, 氂牛, or 犛牛.
7. The reading  うしかもしか of 牛羚羊 is the alternative native name for “gnu.”
8. The native name for “capybara” is おにてんじくねずみ.

Word Notes

1. Dugongs and manatees are collectively often referred to as 海牛.

2. モモンガ and ムササビ are technically different species of flying squirrel with the latter being much larger. モモンガ also has the rare Kanji spelling of 摸摸具和 and ムササビ has the rare Kanji spelling of 鼺鼠. ムササビ may alternatively go by ノブスマ(野臥間・野衾) depending on the region.

3. There is a species of civet native to Japan known as ハクビシン(白鼻心), which is translated into English as the “masked palm civet.”

4. ライオン and タイガー are commonly heard for “lion” and “tiger” respectively.

5.  The word レイヨウ doesn’t quite refer to just “antelopes” but to any of the many closely related species such as gazelles, impalas, etc. In older Japanese, the native reading カモシカ was also applied to these animals as they looked like longer leg versions of the native animal that bears that name. 

6. 麒麟 may also refer to the “quilin” which is a mythical creature from Chinese folklore often described as the ‘Chinese unicorn.’ Though the Kanji both have a high-stroke count, this spelling is very popularized. 

7. 獏 may also refer to the “baku” spirit in Japanese folklore know for devouring dreams and nightmares, which is the inspiration behind the Drowzee-line in Pokémon.

8. 鯱, when read as しゃちほこ, refers to a mythical creature in Japanese folklore.

1. 野生のが山から下りてきた。
The wild bear came down from the mountain.

2. オオカミ(狼)がいないと、ウサギ(兎)が滅びてしまう。

Word Notes:
1. In older language, かげろう could also mean “dragonfly,” which is why 蜻蛉 can either be read as とんぼ or かげろう. 
2. Bees/wasps go by many names in the English-speaking world as is also the case in the Japanese-speaking world. Due to the heightened danger that bee species pose to humans in Japan, it’s best to get your bees-ness in check when in Japan.

2a. アシナガバチ and スズメバチ both relate to wasps, hornets, or yellow jackets by English speakers, but the former has long legs as the name suggests. 

2b. クマ(ン)バチ may regionally refer to “yellow jackets,” but their English name is more accurately “Japanese carpenter bee,” whereas キイロスズメバチ is the native species of “yellow jacket,” which happens to be far more dangerous. Given its dangerous nature, it also goes by the regional names カメバチ (瓶蜂), トックリバチ (徳利蜂), and アカバチ (赤蜂). 

2c. “Giant hornets” are referred to as オオスズメバチ (giant hornet)

2d. 花蜂 may refer to any bee which feeds on larvae and spreads pollen. 
2e. 丸花蜂 refers to “bumblebees.” 

2f. クロスズメバチ and シダクロスズメバチ are native wasps of Japan known for building their nests in the ground. Other regional names for them include ジバチ (地蜂), ドバチ (土蜂), ハイバチ (灰蜂), ヘボ (used in the 東海地方), or スガレ・スガリ (used throughout 東北). 

39. クモ(蜘蛛)の巣は飛んでいるを捕まえる罠です。
spider web is a trap to catch flying insects

40. たまにを手で殺した時に血が付着するけど、あれって僕らの血なの?それともの血なの?誰か教えてください!
Occasionally blood gets on me when I kill a mosquito with my hand, but is that our blood? Or, is it the mosquito‘s blood? Someone, please tell me. 

41. アリ(蟻)を殺すと雨が降る。
When you kill an ant, it rains. 

42. の寿命は長くても数ヶ月程度です。
The lifespan of a butterfly, at most, is around several months. 

43. ハチ(蜂)やスズメバチ(雀蜂)に気をつけましょう!
Be careful of bees and wasps

Word Note: “Bee-sting” is 蜂刺され, and “to be stung” by a bee is: 刺される (to be stung), 噛まれる (to be bitten), or 食われる (to be bitten).

Fish-related Kanji are particularly diverse in number, and many fish have several Kanji associated with them. Moreover, there are many fish with regional names as well as fish names that do not refer to the same fish depending on region. Even for the spellings listed above, this is by no means exhaustive.

Word Notes:

1. One such word that is very common but difficult to ascertain is ゴリ.  Written in Kanji as 鮴, it most often refers to freshwater goby, which may also go by the name ヨシノボリ(葦登). In some regions, though, it may refer to “sculpin,” which is generally カジカ(鰍) in Standard Japanese. Yellowfin goby (マハゼ・真鯊), on the other hand, which is common on sushi menus worldwide, is usually differentiated as such despite being a kind of goby. 

2. スルメ(鯣)refers to “dried flying squid,” whereas スルメイカ(鯣烏賊)refers to the living creature.

3. When sea urchin is used in seafood products, it may be spelled as 雲丹, but this spelling is not preferred when referring to the live animal. 
4. Confusingly, the Kanji 鰒 may both refer to abalone (アワビ) and the pufferfish (フグ), though the latter meaning is rare.

5. Confusingly, the Kanji 鰍 may refer to sculpins (カジカ) as well as loaches (ドジョウ),  but it can also even more confusingly refer to hamachi (young amberjack) in which case it is read as イナダ. Usually, it refers to カジカ with the other fishes being spelled normally as 泥鰌 and イナダ respectively. 

6. To complicated matters, many communities across Japan have developed numerous names to refer to the same fish but for different stages of growth of said fish, and these words in turn can also differ from community to community. Such fish are known as 出世魚(しゅっせうお). Many of these words have become quintessential in marketplaces as well as sushi/Japanese-themed restaurants across the world. The greatest example of this involves the amberjack, known as ブリ(鰤) when fully grown. When not fully grown, its name differs by dialect.

SizeEast JapanWest Japan
Small Fry モジャコ(藻雑魚) モジャコ(藻雑魚)
20 cmワカシツバス
40 cmイナダ(鰍)ハマチ(魬)
60 cmワラサ(稚鰤)メジロ
80 cm+ブリ(鰤)ブリ(鰤)

モジャコ may also refer to small fry of another species of amberjack known as the カンパチ(間八)- the “greater amberjack” in English – which also finds itself on sushi menus. It, too, is so important that its younger versions have different names based on the growth stage of the fish. In the Kanto (greater Tokyo area), it goes by: ショッコ(35 cm or below) → シオゴ(汐子)(35-60 cm) → アカハナ (60-80 cm) → カンパチ (80 cm+).

7. The bass (スズキ) is a 出世魚: コッパ (0-10 cm) → セイゴ(鮬)(10-25 cm) → フッコ (25-35 cm) → スズキ (35- 60cm +) → オオタロウ (old fish). 

8. The striped mullet (ボラ) is a 出世魚: オボコ (0-10 cm) → イナッコ (10 cm)・スバシリ (10 cm)  → イナ (10-30 cm) → ボラ (30-50 cm+) → トド (old fish).

9. The sardine (イワシ) is a 出世魚: シラス(白子)(0-1 cm) → カエリ (1-10 cm) → コバ(小羽)(10-15 cm) → チュウバ(中羽)(15-20 cm) → オオバ(大羽)(around 20 cm). 

10. The words 鮫 and 鱶 are not examples of 出世魚. Rather, the latter exclusively refers to large-sized sharks, which is popularized by shark fin (鱶鰭). 

11. 海牛 when read as ウミウシ and when read as カイギュウ do not refer to the same animals. The former is “sea slug” and the latter refers to “manatees/dugongs.”

12. Just as with other words ending in ~類, 貝類 refers to all “shellfish” as a group of animals. In everyday speech, they may be simply referred to as 貝. 

13. Though snails are not typically viewed as sea-dwelling, there are such thing as sea snails, and snails are actually a kind of mollusk, which is why they are listed along with other mollusks. 

14. 魚 is marked with an asterisk because of how it is the overall word for fish, and thus, wouldn’t typically be written in カタカナ. As for the reading うお, this actually derives from the original native word for “fish,” which was いを in earlier stages of the language. うお can still be seen in many set phrases. 

44. 近い将来、海のが絶滅状態になるかもしれない。
In the near future, the fishes of the sea may become extinct. 

45. 引き上げる度に、10~20匹ずつ網にカニが付いてくる。
Each time I lift the net up, 10-20 crabs are in it. 

46. 東京の葛西臨海水族園に訪れた人たちは勢いよく群れで泳ぐマグロ(鮪)の姿を楽しんでいました。
The people who visited the Kassai Marine Aquarium in Tokyo were enjoying seeing the schools of tuna swimming energetically. 

47. フグ(河豚)を食べる国は日本以外にはどれくらいありますか?
How many other countries are there aside from Japan where people eat puffer fish?

48. 妊娠中にはイカ(烏賊)やタコ(蛸)を食べてはいけない。
You mustn’t eat squid or octopus while pregnant. 

49. うなぎ(鰻)釣りの餌は何がいい?
What sort of bait is best for fishing eels

50. サメ(鮫)は滅多に人間を襲わない。
Sharks seldom eat people.

Word Notes:

1. There are several reasons as to why certain plants have multiple Kanji. Some may be most common when used as surnames, whereas the large majority of the diversity is due to the creation of Kanji by Japanese people overtime to write native plant life. Species of oak particularly have the most available Kanji. 
2. Words with an * are shown in ひらがな as opposed to カタカナ because they are not species names but plant-related words that are especially common.
3. 海藻, as well as 藻 (algae), which is not listed, are not all technically plants but they are related to them nonetheless.
4. The “lotus” has various other names: 芙蓉・水芙蓉・不語仙・池見草・水の花.
In Buddhism, it is referred to as the 蓮華.
5. The technical word for “grass” is 草本.
6. The technical word for “tree” is 木本. You will also see the Sino-Japanese 樹木, which is synonymous with 木・樹. 

51. バラ(薔薇)の咲く楽園へようこそ。
Welcome to paradise where roses blossom. 

52. その畑には多くの樹木が並んでいました。
Many trees were lined up by each other in the field. 

53. 庭にを植えたいです。
I want to plant bamboo in my yard.  

54. 家の庭に果樹を植えてはいけない。
You can’t plant fruit trees or cherry blossom trees in your yard.

Fungi Kingdom (菌界)

It would be remiss to not mention fungi given that they are in our everyday lives in the form of mold and most importantly mushrooms. Many of the fungi mentioned below are endemic to Japan, and both edible and poisonous species are listed.

Word Notes:

1. Although a very rare Kanji, 醭 specifically refers to mold found on liquids. 

2. The Kanji 菌 originally means “fungus” and was later purposed in words such as 細菌 to mean “bacteria.”
