Concentrations up to 100 times higher than previously reported for other marine animals
Origins of cocaine under investigation, theories include illegal drug labs or drug users' excrement and feeding on lost or dumped bundles by drug traffickers
Potential impact on marine ecosystems and inhabitants, may make sharks more aggressive and unpredictable, could damage their eyesight affecting hunting abilities
Thirteen sharpnose sharks off Brazil's coast test positive for high levels of cocaine
In recent news, a startling discovery has been made regarding the presence of cocaine in sharks off the coast of Brazil. Thirteen sharpnose sharks were tested by various research groups, including the Cape Eleuthera Institute and the Oswaldo Cruz Foundation, revealing that all samples contained high levels of cocaine in their muscles and livers. The concentrations were up to 100 times higher than previously reported for other marine animals.
The origins of this cocaine are still under investigation, with theories suggesting it may be coming from illegal drug labs or the excrement of drug users. Another possibility is that the sharks could have been feeding on bundles of cocaine lost or dumped in the sea by drug traffickers.
This discovery raises concerns about the potential impact of drugs on marine ecosystems and their inhabitants. While it is not yet known how cocaine affects sharks, some experts suggest it may make them more aggressive and unpredictable. Additionally, exposure to cocaine could damage sharks' eyesight, affecting their ability to hunt.
Further studies are required to fully understand the implications of this finding. In the meantime, it is a reminder of the far-reaching consequences of human drug use and pollution on our natural world.
Thirteen sharpnose sharks from the waters off the coast of Brazil tested positive for cocaine.
The concentration of cocaine was as much as 100 times higher than previously recorded in other marine animals.
Cocaine could make sharks more aggressive and unpredictable.
Exposure to cocaine could damage sharks’ eyesight, affecting their ability to hunt.
The drugs could also reduce sharks’ life-expectancy.

The article contains selective reporting and sensationalism. The author only reports details that support the theory of cocaine in sharks without mentioning any potential sources of error or alternative explanations. The author also uses emotional manipulation by implying that the findings are 'worrying' for the marine ecosystem and that exposure to cocaine will damage sharks' eyesight and reduce their life-expectancy, but does not provide any evidence for these claims.
Theories have emerged after sharks from the waters off the coast of Brazil have tested positive for cocaine.
There are also fears that exposure to cocaine will damage sharks' eyesight, affecting their ability to hunt.
Another theory is that they could have been feeding off bundles of cocaine that were lost or dumped in the sea by drug traffickers.

High levels of cocaine were detected in the muscles and livers of the sharks
Cocaine may harm the health and behavior of sharks, but further studies are required to confirm this

The author makes an appeal to authority when quoting Dr Rachel Ann Hauser-Davis and Dr Enrico Mendes Saggioro. The author also uses inflammatory rhetoric by describing the findings as 'worrying' for the marine ecosystem.
“We don’t get much coke at sea’
“This may be the case, as cocaine targets the brain, and hyperactive and erratic behaviour has been noted in other animals.”

The author expresses concern for the potential harm caused by cocaine to sharks and their ecosystem. However, he also mentions that the cocaine may make feeding frenzies more likely without providing any evidence or citing any scientific studies to support this claim.
The cocaine was probably harmful to the health of the animals, she said. It was not known if it affected their behaviour, rendering them more aggressive and unpredictable or making feeding frenzies more likely.
]We don't get much coke at sea[...] It's a possibility and further studies are required.[
Sharpnose sharks off the coast of Brazil have been found to have cocaine in their system, with concentrations up to 100 times higher than previously reported for other aquatic creatures.
This is the first study conducted on whether sharks are affected by cocaine presence in oceanic pollution.
All 13 Brazilian sharpnose sharks tested positive for cocaine levels significantly higher than previously reported in other marine animals.

The article contains an appeal to authority and a potential overgeneralization. It mentions the concentration of cocaine in sharks being 100 times higher than in other marine animals, but does not specify if this is a direct comparison to another specific species or an average of multiple species.
The drug was found in all wild Brazilian sharpnose sharks tested, with a concentration as much as 100 times higher than previously reported for other aquatic creatures.
