Matt Landos, an ichthyologist at the Australian College of Veterinarian Scientists, investigated mutations in fish in the Noosa Basin and concluded that they were caused by chemicals from a nearby macadamia plantation. This was reported by the AFP agency.
As the biologist established, the mass death of fry in river fisheries is caused by a mutation that does not allow the fry to live for more than two days. Most often, fish hatched from eggs with two heads. The same deformity was noted in the poultry and sheep farms adjacent to the plantation. “This is the first time I've encountered such a mutation in ten years of work,” says the scientist. "The tests I ran using water from the Noosa River exclude bacteria or viruses." Matt Landos suspects that the organophosphorus fertilizers carbendazim and endosulfan, which are banned in many countries, but not in Australia, are the cause of the deformities.
Mutations in living organisms can be caused not only by chemical, but also by unfavorable biological effects. Thus, parasitic microorganisms that damaged frog eggs became the cause of the appearance of the fifth paw in frogs in some areas of the United States. The same deformity was recorded in the UK in the Nene River in Cambridgeshire. And in the Moscow River, external deformities and diseases in some species of fish make up 100% of the population (for example, the chub suffers from cirrhosis of the liver).

Twins With One Body For Two Were Supposed To Die At Birth, But Have Been Living For Two Years
The girls Kelly and Carter Torres were born with one body half below the ribcage. This type of Siamese (conjoined) twins is very rare, it is called omphalo-sciopagus and makes up only 5% of all Siamese twins. In addition, this type has a very high mortality rate and when Kelly and Carter were born, they were very weak. The doctors said it would be a miracle if they could live even a day. The survival rate of omphalo-ischiopagus is only 40%. But the other day the girls turned 2 years old. They are still needed
Alligator Fish, One Of The Most Frightening And Largest Freshwater Fish
Outwardly, this predatory monster looks like a hybrid of an alligator and a fish, for which it is logically called an alligator pike. Its official name is Mississippi carapace (Atractosteus spatula). With the exception of some fish that are found in tropical countries, the alligator pike is one of the most frightening in appearance and the largest in size of freshwater fish. But it can also be found in the salty sea waters of the Gulf of Mexico, and the fish does not feel any discomfort. It looks like an ancient prehistoric
Twins From Two Different Fathers Were Born In China
On March 25, the Taihai website posted a message about twins born to different fathers. And this is not fiction at all, but a very real story. Recently, the head of the Zhengtai Forensic Authentication Center in Fujian Province in Xiamen, Ms. Zhang, told reporters about a case she faced in her professional career. A married couple came with two twins to do a genetic paternity test for registration. Res
Two-mouth Fish Caught In New York State
New Yorker Debbie Geddes went fishing with her husband last week on Lake Champlain, near the Canadian border. At some point, Debbie felt that a fairly large prey had fallen into her bait and she happily began to carefully pull it out. “I was hoping that she would be as big as it felt. But when I pulled her into the boat and examined, I could not believe my eyes. She had two mouths!” - says Debbie. At the same time, the woman was also surprised
Two Uterus And Two Vaginas: Australian Was Born With A Rare Anomaly And Successfully Gave Birth Three Times
When Lauren Cotter, 34, from Melbourne was 16 years old, a gynecologist diagnosed her with a very rare abnormality called Uterus didelphys. This means there are two vaginas and two uterus. Moreover, everything is in working order and fully developed. Because of this anomaly, Lauren was told that most likely she would never be able to conceive and carry a baby on her own, but since then the woman has successfully given birth to children three times, including twins. This condition occurs in about one woman in 3 thousand
