When a clam is put in water, it can see that its tongue is alive.

When selecting, we should pay attention to the following points:

1. Choose the shiny shell. Different varieties have different colors, white clams are whiter, and flower clams are darker.

2. A clam that opens its mouth in the water may have been dead for a long time.

3. Choose the one that sticks out its tongue, and when it touches it, it will retract to show that it is alive, and the meat tastes delicious.

Introduction to the aged clam

On November 13th, 213, the actual age of the oldest creature in the world was more than 1 years older than previously estimated. But unfortunately, this 57-year-old "old" mollusk has been accidentally killed by scientists.

Found

This kind of clam named "Ming" is a deep-sea round clam. In 26, researchers fished it from the bottom of the North Atlantic and put it in a freezer for further research. However, when researchers pried open its shell to analyze it, the signs of life gradually disappeared.

age calculation

Paul Butler, a marine scientist at Bangor University in the UK, said: "The first time we made a mistake, maybe we were busy publishing our findings and were a little hasty. But now we can absolutely confirm that we have got the correct number. "

By calculating the growth ring number on the inner shell of this mollusk, the researchers initially estimated the surprising result. Ming is 45 years old! This result has been certified by Guinness World Records.
