The editor from Tuliu.com will now take everyone through it.

I. How much is pufferfish per jin

The price of pufferfish is roughly around 35-100.

1. The market price of pufferfish is related to the variety and place of origin; the most common price is around 35 yuan to 80 yuan per jin.

4. Wild pufferfish is very precious and also very rare. The price is very high. Nowadays they are generally artificially farmed, with prices at around 35 to 100 yuan per jin.

II. Why pufferfish puff up

1. If frightened in the water, a pufferfish generally drinks about 35 mouthfuls of water within 14 seconds, and its volume increases accordingly. Having taken in enough water, the gill slits all close tightly, and strong valves also spring out from the upper part inside the mouth, acting as a seal. When the mouth cavity contracts, the water can only be injected into the esophagus. As the water pours in, the stomach expands to 100 times its normal volume. Its skin is also especially suited to expanding. The skin made of wavy fibers stretches freely, swelling up tight. Therefore it is a “water balloon”, not an “air balloon”.

2. If it is caught out of the water, with no water to drink, how does it puff up? At this time the pufferfish inhales air into a sac-like structure connected to the stomach, and then as described above, it expands.

III. What happens if a puffed-up pufferfish is pricked with a needle?

Next, let us discuss it by case.

1. If you stab down with a needle and puncture only the outer skin, not much will change. The pufferfish will begin to struggle.

2. If you stab down with a needle and pierce the muscle tissue, there also will not be much change. The pufferfish will struggle violently.

3. If your needle pierces the stomach, there are the following two cases:

(1) Your needle is very fine; after a small amount of water begins to seep out, because the stomach muscles have stretch and contractility, and the wound is very small, the wound quickly seals, and the amount of water seeping out is relatively small. The volume will not change much. But afterward, after it returns to normal, hmm, it will die.

(2) Your needle is very thick, as thick as a gel pen refill; the wound is very large, and the speed of water seeping out is far greater than the speed of the wound closing, so the volume will become smaller. Then it dies.

4. The result of pricking one that has puffed up by inhaling air is still as described above; gas diffuses very slowly through the damaged part, because the muscle tissue closes and the pressure inside and outside the sac instantly returns to balance.
