In April 2021, a Scottish woman shared on social media a series of eye-catching photos taken on a beach in the Hebrides Islands outside England, showing a vertebrae winding through the sand, with a section of vertebrae, very large and nine meters long.
The photo quickly sparked heated discussion, with some believing it to be a prank, others believing it might be a work of art, and some even thinking it might be a legendary keel, but experts eventually identified it as a whale backbone, and before the incident had passed, another strange thing happened on the western coast of the United States.
A large number of cakes appeared on the beaches of Oregon, usa, and some of them were still moving
In August 2021, thousands of round cake-like objects suddenly appeared on the beaches of Oregon, some of which were still moving, visually measuring about 8 to 10 centimeters in diameter, scattered on several square kilometers of sand, looking like someone was deliberately drying okara cakes, but in fact it was not artificial, it was an abnormal natural phenomenon.
Visitors to the beach are curious, what is going on? A set of photos taken by someone and posted to the Internet, according to experts, the round cake-shaped object is actually a marine animal called "sand money", because sand money looks like a coin, also known as sand coin, sea money.
Sha qian belongs to the sea urchin family and has long lived in the intertidal seabed, even distributed in the seabed at a depth of 3,000 meters. Although sand money is located in the marine food chain, very few creatures are interested in sand money, only a fish called the ocean fish, which sometimes eats sand money that is difficult to swallow.
But somehow, this time, thousands of sand money were suddenly washed up on Oregon beach by the tide at once, and when the tide receded, they were left on the dry beach, and some were still moving.
Sha Qian is not an amphibian, can not walk on land, at most is slowly moving on the beach containing seawater, burying his body in fine sand, after being washed ashore by the sea, in the sun, generally dehydrated and died within a few minutes. So it's suicide.
Is it a sign of climate change?
Why is there suddenly a lot of sand money on Oregon's Sleep Bar Beach? Netizens are talking about it, and even experts from the Oregon Aquarium are confused, because this phenomenon is the first time this phenomenon has appeared in Oregon beaches. Therefore, it has once again aroused heated discussion.
Some people suspect that this abnormal phenomenon may be a sign before the earth's climate changes, because there are too many bad climatic events in 2021, high temperatures, droughts, tornadoes, floods, wild burns, many people are about to become "birds of fright", as soon as they hear that there are strange things happening, the first thing will ask: The climate is going to change again?
So, is the stranding of a large amount of sand money a sign of climate change? There are no facts to prove this claim correctly, and after a large amount of sand money has been stranded, there have been no events related to climate change, and it seems that it is a sign of climate defecation.
However, professionals have provided two speculations for your reference, one may be the cause of the serious pollution of this ocean, resulting in a large number of deaths on the seabed sand money, and then washed onto the coastline by the tide, and second, it may be the reason for the rapid change in sea temperature, resulting in the shallow water sand money being cooked.
In June 2021, the sea temperature also became very high due to the hot weather, and a large number of marine animal carcasses stranded along the coastline of the United States were cooked by excessively high seawater.
Experts warn
Sha Qian is small, furry and looks so cute that it may cause some tourists to have the impulse to take it home, but experts warn about it: don't take live sand money home for two reasons.
First, the United States has a clear rule that it is not allowed to take live sand money from the beach home, and in Florida and South Carolina, if a piece of live sand money is taken from the beach, it can be punished with up to $500 and possibly imprisonment. Second, sand money is easy to die after leaving the ocean, and live sand money has an odor, which will cause indoor air to become very bad.
Live sand money can secrete a pigment called "echinoderm pigment", the body color from dark brown to bright purple, so to determine whether it is dead, you can put it in your hand first, if the color of our hands changes, it means that sand money is still alive. If the color of the hand does not change after holding for a minute, it is dead.
The beach has run aground several times for strange objects
In the world, beaches have repeatedly stranded strange objects, and in 2017, a large amount of yellow sponge-like foam suddenly appeared on the beaches off the northern coast of France, and no one knows what it is, but experts remind tourists that it is a wise thing not to touch unknown objects, because there is no certainty whether it is poisonous for the time being.
In 2019, an object with a white skeleton appeared on the beach in North Carolina, usa, and it was impossible to determine what it was, it looked very strange, what kind of animal was it? Some speculate that it is a sick tube worm, the lesion makes it grow a white skeleton, and some people think that it is the remnants of the puffer fish after decomposition.
