Obscure kanji for fish. Can you read them? (1–10)
stonefish

scorpionfish
Scorpionfish are very tasty when you eat them. But as everyone knows, they aren’t exactly beautiful to look at. The kanji “虎魚” (literally “tiger fish”) seems to be an ateji, while the name okoze itself comes from “oko,” meaning ugly, and “ze,” meaning fish—so the name literally means “an ugly fish.” It’s a bit pitiful, isn’t it?
pufferfish

pufferfish
The pufferfish, known as a poisonous fish and one that inflates. I hear it puffs up as a threat display, but it ends up looking kind of cute, doesn’t it? The kanji “河豚” literally means “river pig.” It’s said to have been named that because its swollen appearance resembled a pig.
ocean sunfish

ocean sunfish
The ocean sunfish you often see at aquariums. It has a distinctive, unique appearance, but in fact it’s a very sensitive fish. It’s also sometimes written as “曼波魚.” The word “翻車” refers to a waterwheel, and it can also mean an overturned wheel. It might indeed resemble the shape of a sunfish.
anglerfish

monkfish
In fact, anglerfish aren’t good at swimming. I’ve heard the kanji are ateji (phonetic characters). The fish radical was added to the characters for “peace” and “health,” inspired by the sound of ankō. There are various theories about the origin of the name, but it’s commonly said to come from angō, a dialect word for toad, which resembles it in appearance.
Japanese amberjack (yellowtail)

gurnard
The gurnard, known for its distinctive appearance with large pectoral fins and also regarded as a high-end fish. The origin of its kanji is unclear, but as for the name “hōbō,” there’s a theory that it comes from the sound of its call produced using its swim bladder. Another way to write it in kanji is 「魴鮄」.
