HUNDREDS of bizarre sea creatures armed with toxins “deadlier than cyanide” have been found washed up on a beach by a Brit.
Scientist Tess Gridley made the terrifying discovery at Muizenberg Beach in Cape Town, South Africa, while out walking with her family.
Now marine experts have identified the bizarre looking creatures as lethal evil-eye pufferfish and have warned locals to steer clear.
Dr Gridley, who moved to Africa from Sheffield more than a decade ago, estimated that hundreds had become beached on the sands.
“The beach is 200 metres from our house and we were on a family walk,” she said.
“I can’t say how many were there as I only looked in a small area – I was with my kids and dog, and prepping for fieldwork so it was a short visit.
“But if you did count it would have exceeded hundreds.”
The South Africa’s Department of Environment, Forestry and Fisheries said the species carried a killer neurotoxin called tetrodotoxin.
It’s a poison more lethal than cyanide and it causes death by respiratory failure after paralysing the diaphragm.
The ministry’s statement read: “The fish mortalities in False Bay are exclusively of the evil-eye pufferfish with counts of 300 to 400 dead fish per km of shore.
“These dead fish all carry the deadly neurotoxin tetrodotoxin and should not be eaten; death comes usually by cardiac arrest.
“Beach dog walkers are strongly advised to keep their pets away from them.
“If one’s dog does eat whole or part of a pufferfish, immediately induce vomiting and rush your pet to the vet.”
One pet has already been killed as a result of the mass stranding, according to the AfriOceans Conservation Alliance, a local NGO.
Meanwhile, the cause of the incident remains a mystery.
Previous mass strandings have been caused by red tides – an algal bloom that changes the water’s colour, and which produces natural toxins.
However, the ministry statement notes that “there are no reports of any adverse water conditions or red-tide toxins that may have caused this”.
It’s also possible that the fish were blown to shore after puffing themselves up, either during a mass courtship or as a response to big waves.
In any case, Dr Gridley – who studies marine life as part of the Sea Search organisation – believes the public has a part to play in future strandings.
“Keep a look out and report what you see,” the mum-of-two said.
“Don’t be alarmed, these events happen from time to time in natural systems.
“There is now an important role for citizen scientists in reporting these events through social media. We are learning a lot more about the marine environment these days from such reports.
“If possible, collect photos and videos which can then help to identify species, and offer interesting insights into what’s living in our oceans.”

There’s a big stink along Ogdensburg’s Maple City Trail as thousands of pond fish are found dead and some are washing into the Oswegatchie River.
It’s not a pretty sight. Thousands of dead fish washed up on shore in this pond just off the Oswegatchie River – and right along the popular Maple City Trail.
“When first noticed just 20 of them, I thought that was alarming, and then to come down and see hundreds if not thousands,” said Jim McCarthy, Ogdensburg resident.
McCarthy walks the trail with his wife. He is also an avid angler, but he has never seen a die-off on this scale. He reported it to the state Department of Environmental Conservation.
“There’s carp, blue gill, bass, perch, crappies, shiners,” he said.
The DEC investigated. It says the most likely cause is a winterkill.
They’ve been seen around the state this year. Heavy snow cover on ice prevents plants below from producing the oxygen fish need. The dead fish are being seen on the Oswegatchie as well because, according to the DEC, “A culvert connects the wetland to the river and dead fish (mostly carp) are moving from the wetland to the Oswegatchie River through the culvert.”
Some people think ice buildup on the Oswegatchie a few weeks ago may also have cut off the culvert as a possible escape route for live fish.
People say the walking trail is a little less popular these days. They say the stench from these fish is really something on a warmer day.
Local wildlife is also getting in on the act, pecking and tearing at the dead fish.
“Some days it’s overwhelming. We’ve actually had to quit walking the trail for a few days because you couldn’t stand breathing in that, that…,” said McCarthy.
From here, it looks like nature will take it’s course. But it may be a while before the Maple City Trail sees its regulars again.

Hundreds of dead fish have been seen floating in the Swan River in Perth, prompting an investigation.
The Parks and Wildlife Service says at least 600 dead fish have been reported in the river near Garratt Road Bridge in Bayswater and upstream in northeast Perth.
“Significant rainfall and increased flows from the Avon River may have contributed to the fish kill,” the Department of Health and the Department of Biodiversity, Conservation and Attractions said in a joint statement on Saturday night.
“An increased amount of debris is also expected to float downstream in coming weeks following the large rainfall event.”
The fish are mostly bream.

In recent days, bad luck has happened in Japan. First an earthquake and then large-scale dead fish appear off the coast of Tokyo. Does the appearance of these large-scale dead fish have anything to do with the earthquake in Japan? Why are fish dead on the coast? What did these fish go through? Is this a bad omen?
Japan is an island country, although with a small area, the coastline is 29,751 km long. The mass death of fish also seems to happen regularly in Japan. In June 2012, tens of tons of sardines appeared on the coast of Chiba Prefecture, Japan, the entire port was almost full of dead fish, the beach The sea looks like a rug made of sardines.
In January 2018, a large number of sardines appeared on the coast of Aomori prefecture, Japan, covering a coastal area more than 40 kilometers long. This incident also happened quite strangely, after all, cases of sardines on such a large scale are rare and of unknown cause. But experts tend to believe that the sudden drop in seawater temperature is the main cause of the mass death of sardines.
With the exception of Japan, widespread fish deaths occurred on the coasts of the United States and Indonesia. The phenomenon of fish death on the coast of Tokyo, Japan is basically the same as before and experts have not given the exact cause of this phenomenon.

Wildlife officials say cold temperatures from Winter Storm Uri are likely what left thousands, perhaps millions of dead, smelly fish floating in residential canals on North Padre Island.
Marvin Jones has been leading the clean up effort of the island canals the past few days.
“So far in the last few days, we’ve managed to scoop up and bag and haul off about 15 to 18 tons (of fish,)” said Jones, president of Padre Island Property Owner’s Association.
The association is responsible for the clean up because it owns the canals.
He estimates the clean up will take another week or two to return the canals to pre-storm conditions.
“There’s still thousands and thousands of dead fish,” he said.
City Manager Peter Zanoni said the city has been helping by throwing away fish residents have collected.
“We’ve been taking bags and bags and fish to the landfill,” he said.
City staff started working Friday afternoon to identify equipment that it could use to help collect fish from the canals.
“The amount of fish washing up is greater than what it was earlier in the week. It’s almost too much for them to handle by themselves,” Zanoni said.

A police report has been lodged against a factory along the Prai River here after thousands of dead fish, including catfish and spotted scats, surfaced.
Seberang Prai city councillor P. David Marshel said residents in Taman Kimsar alerted authorities to the problem on Tuesday afternoon (Feb 9).
He said Prai assemblyman Dr P. Ramasamy, who is also Deputy Chief Minister II, and councillor K. Jason Raj arrived at the scene and found the riverbank covered with dead fish.
“The council’s Crisis Department was immediately alerted.
“Water samples and fish carcasses were taken to the Department of Environment (DoE) for tests.
“The cause of the deaths is still unknown, but we received information regarding the release of untreated water into the river by a factory operating beside it.

Thousands of tilapia cultivated in Ngebel Lake have died since Monday (8/2/2021) yesterday. Residents suspect that tens of tons of fish suddenly died of sulfur gas poisoning from the bottom of the lake since Sunday (7/2/2021) night. The head of the Milled Fish Cultivation Group, Yoso Ngebel, Pujo Widodo, said that the phenomenon of sulfur gas coming out of the bottom of the lake occurs almost every year. However, usually sulfur gas does not come out during the rainy season. “Before the sulfur gas comes out, usually the farmers have emptied their kerambanya,” said Pujo to Kompas.com , Tuesday (9/2/2021).
However, the community missed predicting the time for sulfur gas to come out from the bottom of the lake. Sulfur gas comes out when farmers are about to harvest tilapia. As a result, thousands of tilapia fish died suddenly and floated on the surface of the water. According to Pujo, a group of farmers could lose up to tens of millions of rupiah, depending on the number of cages they have. Most of the dead fish were used as catfish food. Meanwhile, fish that can be saved are sold cheaply. Not only tilapia, many residents cultivate carp and catfish in Ngebel Lake. The two fish commodities were able to survive even though gas bursts came out of the bottom of the lake.

When Fiskejournalen talks to Greger Johansson on Monday morning, he has already sat on the phone and talked to lots of people who have heard from him, since he posted the pictures on Facebook. The discovery of the dead fish quickly became a snack bar, and the big question is of course what caused the mass death?
There must have been at least 20,000 fish, maybe more. I have never experienced anything like this in my entire life, so it is clear that I was surprised, says Greger Johansson.
Now he wonders if there are more fish scattered on Fårö’s beaches, or if it is only at the current location? He himself is of the opinion that something extensive must have happened.
A friend has seen lots of trawlers north of Fårö, so maybe something has happened in connection with it, maybe that something has broken? In any case, it is terribly sad, says Greger Johansson, who hopes that the mystery will clear up when the event becomes known to a larger circle.

Terrible the panorama that was appreciated this Monday in Bellavista beach in the municipality of Guasave where thousands of fish, apparently sardines , flooded the sand for three kilometers.
Walkers from the receivership of La Brecha who went to the resort were able to document through a video recorded with their cell phone, the impact that high seas fishermen who circulate in the maritime zone off the coast of Guasavense are apparently committing .
When questioned in this regard, some fishermen in the area say that it is possible that some of the larger vessels have discarded the fish that were trapped in their nets and that, since it was not commercially attractive, they only threw it into the waters and was finally expelled by the sea.
At the site there was also a dead turtle, so he tells the family that he took the shots and they do not know if it was a natural phenomenon or an ecological damage committed by the fishermen.
