Hideki's Yuruyuru Nagisahoki/ep8-"Find discomfort!" Quiz 2-

Ojisan, healed.

Hello! I'm Hideki who loves nature and the outdoors, both the sea and the mountains.

This GW has spent 5 days and 4 nights on the coast of Nishiizu, which I love, while sleeping in my favorite 4WD.
Watching the sun set over Suruga Bay and surrendering yourself to the sea breeze until the night falls, at dusk, soaking in a secluded hot spring while looking up at the starry sky healed an old man who was a little tired both physically and mentally. .

*Twilight time in Nishiizu with a view of Suruga Bay. nice time

Well, that's about it for the recent status report (I'd like to write a proper article here)
The previous"What's this? Quiz"was very well received, so this time Nagisa Houki will follow up on the previous one as "Quiz 2"!

This quiz is different from last time.
Then, please try the "2nd Nagisa Quiz"!

Question 1

As usual, I was able to find a variety of shells when I walked along the coast of my hometown, Chigasaki.
Well, here is the first quiz! ! Among the snails A to H in the photo, I'm out of the group... No, that's not a very good word. Which one of these things is the only thing that is different? While thinking about the reason, please take a good look and look for "uncomfortableness"!

*The hint is something that you may have seen before.

Let's reveal the answer!

Well, the correct answer is...?

E.  was!
The others are all conch shells that live in the sea, but only E is Seashells that live on land (snails) is
Another way of looking at it is Left turn just like this has become You who noticed this, Observation eyes are surudoi!

Most snails are right-handed. Why are most snails right-handed? The ecological reasons are still poorly understood. Snails originally have a gene that makes them right-handed, and if the gene doesn't work for some reason, there are individuals that become left-handed.

In general, many snails are right-handed, but E is thought to be a species called Hidarimakimaimai.
Even among the snail species with many right-handed snails, there are individuals with left-handed snails.

A survey of about 800 species of snails in the world revealed that the ratio of left-handed snakes is high in areas where there are snakes that eat snails, and that there are many right-handed snakes in areas where there are not. Despite the fact that right-handed and left-handed snakes cannot mate and produce offspring, the reason why left-handed snakes, which are few in number, have survived is because they cannot be eaten by snakes, which are external enemies. Snakes that eat snails are able to survive because they prefer to eat right-handed snakes because of the structure of their jaws.

By the way, in Japan, the Iwasaki Sedaka snake, a species of snake that specializes in eating snails, lives only in the Nansei Islands.
I happened to find a left-handed snail on the beach, so I was interested and researched it.

Question 2

Let's increase the types of shells and take the second quiz!

Which one of the pictures ① to ⑮ is different from the first question?
This time, there are more than conch shells! I found this many kinds of shells by walking on the beach for about an hour.

* By the way, the number of shells does not matter!

How is it, do you understand? Was it a little difficult?

May I announce the correct answer?

What is the correct answer for the second question?

③ !It was
All of them look like shells, but only ③ was not a kind of shellfish (molluscs), but a kind of barnacle shell that belongs to the same family as shrimp crabs (crustaceans).

There are times when fishermen sell freshly caught “seafood” on the beach of Chigasaki. There, turtles and barnacles are sometimes lined up as ingredients along with other seafood, with a caption (description) that says, "She's a member of the shellfish family." Every time I see it, I want to tell you, "That's not a shellfish, but a crustacean!" (laughs) By the way, I have eaten it before. It is eaten with miso soup or boiled with salt, and the taste is similar to shrimp crab.
If you are interested, please refer to this site.

Look closely at the pink seashells that look like cherry blossom petals in ⑪. This is a shell of a cherry mussel. Can you see the small holes in it? This hole is the one opened by the clawed mussel in ④. Clams secrete an acidic liquid from part of their feet to soften the shells made of calcium carbonate, and then soften the shells of clams and clams with thick shells, as well as cherry clams. It is a “bivalve eater” that opens a hole with its tongue and eats the contents of the shell.

*If you see a hole like this in a bivalve, please observe it assuming that it is the work of a clam shell.

When I was in elementary school, I saw a clam clam for the first time at a local fishmonger. When I found a strange snail in the clams in the bat, the man at the store said, "You can take it home!", so I kept it at home for a while. After that, I don't have a clear memory of what happened to that snail. By the way, I don't remember eating it lol (it seems that you can eat it)

Question 3

Well then, it's the third question of the quiz using drifting objects!

Which one of the pictures ① to ⑫ is different?
This time, as you can see, there are things other than shells.

* ④ is "baked seaweed", ignoring the bag, only the contents are subject to the quiz

What do you think? Did you find any "uncomfortableness"?

For those who say "I don't know!", let's give a big hint!
However, if you can see the hint, the correct answer is △ instead of ◎, so please observe the above photo a little more carefully.

Here's a big tip!

*The hint is that it is different from the previous photo!

Do you understand now?

What is the correct answer for the 3rd question?
・
・
・
・

⑤!It was
⑤ looks like a coin purse made of resin (with a cat face??), so it's not a "sea creature".
⑤ is the answer, including the fact that it is a land animal (mammal) and not a material derived from the sea!

Didn't the picture on the back of ⑤ look like a "crab shell"?
I came up with this quiz because I misunderstood it while walking on the beach.

*If you put them side by side, they look similar! The elliptical shape and the jagged edges on both sides are particularly crab-like!

If ⑤ is a real crab shell, the correct answer is ⑪ starfish.
The reason is that molluscs (shellfish, squid), arthropods (crabs), and seaweeds (seaweed, Ecklonia japonicus) have companions, but "there is only one starfish, which is an echinoderm." .

Question 4

Now for the final quiz! !

Which one of the pictures a to n is different?
Actually, there is a lot of garbage that is an artificial object that you do not want on the beach.

*Since it's getting late in the evening, the shadows on the beach are getting longer (this has nothing to do with the quiz lol)

The fourth question is "Quiz to explore discomfort", but the key to solving the quiz is to find common points first .
Let's derive the answer from the opposite idea!
When I think about these quizzes, I find and collect drifting objects with the keyword "common point" anyway. Here's a tip! Did you find anything in common?

We will reveal the answer!
What is the correct answer to the final question?
・
・
・
・

c was the correct answer!

The "common point" of this problem is that I collected things that can be called by the letter "ka".
Therefore, the answer is that only c is not a name that starts with "ka".

How was it?
We have delivered "Nagisa Quiz" twice, but did you exercise your brain?

For me, thinking about original quizzes based on things, taking an interest in the things I find, and researching them lead to training to train my “planning brain” and to increase the number of drawers for ideas. increase.

"Let's start with the standard questions for the first question!" Composing is not much different from what we space planners usually do. The point I always cherish is to "disappoint expectations in a good way". Don't you think it's more interesting to have an "unexpected" part that doesn't work as expected?

If you enjoyed this quiz and found it "interesting!"​
Please try the last Nagisa quiz as well!
