[For Preschool & Kids] Quiz Collection on Various Fish

not

Human and animal eyelids are there so they can blink and keep their eyes from drying out. Fish live in water, so their eyes don’t dry out, and they don’t have eyelids.

gills

Humans breathe with their lungs, inhaling and exhaling through the mouth, while fish breathe with gills. Gills perform the same function as human lungs, but because water contains less oxygen than air, gills take in oxygen efficiently.

tuna

Tuna have to keep swimming at high speed to take in oxygen, so if they stop, they can’t breathe. Not only tuna but also other “migratory fish,” such as mackerel, sardines, and bonito, are companions that keep swimming.

Aequorea

Named for the way it swims with a fluffy, pure-white body, the yūrei jellyfish can grow quite large—its bell can reach about 50 centimeters across when expanded, and its total length can be around 1 meter.

tuna

The terms often heard in sushi restaurant commercials—“toro,” “chutoro,” and “otoro”—refer to cuts from the belly of the tuna. These are fatty portions that are very delicious and considered premium sushi toppings.

dorsal fin

The fin on the back is called the dorsal fin. The dorsal fin is mainly needed to change direction and maintain balance so the animal can swim well in the water. Some fish have spiny dorsal fins that they use to attack enemies.

tonguefish (also: sole; common name for marine flatfishes in family Cynoglossidae or Soleidae, context-dependent)

The fish called ushinoshita, named for its cow-tongue-like shape, is also known as sole. It’s a famous ingredient in French cuisine and a very delicious fish.
