Recently, on the beach in Nova Scotia, Canada, someone found that a 13-meter giant whale stranded . At first, there were some signs of life, but the body was very weak. The local Marine Animals Association quickly came to rescue, but the treatment was ultimately unsuccessful.
In order to study the cause of death of this giant whale, after the experts conducted an anatomical investigation, it was a male sperm whale . The appetite of whale is filled with marine garbage, and fishing nets, ropes, thread piles, plastic cups, packaging bags and other items were cleaned up. The weight of is about 300 kilograms. It is these fishing gear that fills the whale's stomach, hinders the sperm whale's digestion , causing serious obstruction in the digestive system of the giant whale, and eventually leading to the death of these whales.
Staff of the Marine Animal Association published a video picture of "The cause of whale stranded death is that the stomach is filled with fishing gear", hoping to attract people's attention to marine garbage, especially sperm whales and other whales can easily swallow marine garbage . The existence of garbage and other plastic problems in the ocean can easily lead to the death of marine organisms.
1. How harmful is marine garbage to whales
In recent years, more and more whales have been stranded. There were more than 900 whale stranding incidents last year . The big reason is that they are injured by entanglement of fishing nets or impacted by ships, and swallowing a large amount of plastic, which causes them to digest.
For example, there are statistics. Taking blue whale as an example, a blue whale consumes a maximum of about 10 million microplastic particles per day, which means that in about one quarter, the plastic microparticles consumed by blue whale can reach 1 billion . The estimated weight of these plastic microparticles is between 0.23 and 4 tons. Blue whale consumes such a large amount of plastic particles , which can easily cause them to get sick and injured.
In December 2019, in the Outer Hebrides of the UK, a sperm whale of more than 20 tons stranded and died. After dissection, the sperm whale's appetite includes fishing nets, ropes, plastic cups, backpacks, gloves, packaging bags, tubes and other items, and it weighs about 100 kilograms of garbage, which will inevitably have an adverse effect on its digestive ability, blocking its digestive system and causing death.
In May this year, a whale about 5.3 meters long stranded and died of stranding in its appetite for more than 15 kilograms of plastic garbage . Whether it is a whale or other marine life, microplastic damages to marine life. Therefore, in order to reduce marine garbage, the use of plastics should be reduced, and plastics should not be discarded. Also, pay attention to missing, discarded and discarded fishing gear.
2. Sperm whales and ambergris
ambergris can be used as a high-end spice. It is very expensive, but it is also very rare and difficult to obtain easily, because ambergris not all whales have . It is a wax-like substance that occasionally forms in the intestines of sperm whales. This substance is relatively rare and needs sperm whales to prey on the king squid.
When a sperm whale preys on giant squid , it swallows the prey in one bite. It is difficult for sperm whales to digest the parrots of giant squid , which also includes the squid's berries of squid, octopus's squid's squid's parrots, etc. They gradually form a viscous dark substance in the small intestine, which will form solid with secretions in the intestine and then be excreted or spit out. This is the origin of ambergris, but not every sperm whale has ambergris , and the probability of ambergris is about 5%.
If you want convenience, hunt sperm whales and take them out directly from their intestines, it will be more of a sausage. The "amberg" that is directly removed cannot be considered a real ambergris, so hunting sperm whales directly is like "killing chickens to get eggs". The price of intestines like is not as high as ambergris . In addition, the sperm whales population has been included in the list of protected animals, and illegal fishing is prohibited.
