We've scoured the Practical Fishkeeping news archives to dredge up some of the weird and terrifying incidents involving fish that we've covered in the past few years...
Attack of the 'willy fish'
The legendary candiru, or 'willy fish' as it sometimes less politely called, is known about well outside its native range in the freshwater rivers of the Amazon basin. These small catfish are parasites and normally live in the gills of very large catfishes, to which they're attracted by the ammonia that is excreted by the fishes' gills.Unfortunately for bathers, gills aren't the only things that can excrete streams of ammonia into water. Humans urinating while swimming also do the same. The tiny catfish home-in on the trickle of ammonia-rich wee and swim up the victim's penis or urethra, locking themselves in place with a set of sharp hooks. Once there, they leave you in immense pain and try to dine on your blood.
Although infamous, "attacks" by these fish are actually not thought to be particularly common. We covered the first confirmed and documented case of the removal of one of these catfishes from a man's penis. There's also a video, and a dramatic reconstruction of the event, if you're not too squeamish.
While candiru are normally small fish – an inch or two at most - the catfish removed in this case wasn't a little one. It measured an eye-watering six inches in length and half an inch wide! Given the choice, I think I'd personally prefer to be stung by something instead...

Flying fish jumps into man's eye
While numerous boaters have been injured by Silver carp (Hypophthalmichthys molitrix) and sturgeons leaping out of the water, most are lucky enough to come away with just cuts and bruises. However, one patient admitted to a hospital in Guadeloupe was rather unluckier.He was quietly enjoying the Caribbean sun when a needlefish leapt out of the sea and impaled his eye socket. The fish tried to flap free, causing serious damage to the man's optic nerve. It eventually snapped off its beak, leaving it stuck inside the man's eye socket.
Perhaps most amazingly, the man waited five days before popping in to casualty to have the lump of bone removed from his mangled eye socket. Consequently, even after the remove of the bone fragments and a course of antibiotics he lost the sight in the affected eye...

Steve Irwin killed by stingray
Although they're potentially dangerous, deaths by stingrays are actually relatively uncommon, so the news that television reptile expert Steve Irwin had been killed by a Bull ray while filming off Queensland was all the more shocking.Irwin was believed to have been snorkelling over some large rays when one of them whipped up its tail and its large, barbed venomous sting struck him in the chest – pretty much the worst possible place there is to get stung by a ray. Given the wound Irwin suffered when he was struck in the chest, there was probably little that could be done to save him.
However, research undertaken by scientists from the University of California, who examined clinical records on 119 people who had been stung by stingrays, suffering acute but non-lethal pain in the process, showed that most had pain relief within half an hour by submerging the wound in hot water.
Stingrays are found over a very wide area and a number of commonly kept in aquariums, especially the freshwater species from South America. Research has shown that it's actually these species that give the most painful stings, with even a small nick from the stinger enough to result in an exceptionally painful wound. Fortunately, stings from freshwater rays in the aquarium are extremely unusual because fishkeepers tend to treat them very cautiously.

Men hallucinate after eating fish
Two men got more than they bargained for when they dined on a popular local seafish in Mediterranean restaurants in 2006. The men suffered from "terrifying" visual and auditory hallucinations - seeing and hearing things that weren't really there - after eating the Salema porgy, Sarpa salpa.The fish had been eating algae containing an indole toxin with similar effects to the recreational drugs LSD (lysergic acid diethylamide) and DMT (dimethyltryptamine) which left the men suffering from a rare case of Hallucinogenic Fish Poisoning or ichthyallyeinotoxism.
Apparently, Sarpa salpa is known to be affected by this algae and was once known as the Dream fish and was even used as a recreational drug in Roman times. The men "tripped" for 36 hours after eating the fish, suffering from various hallucinations and nightmares in the days that followed...

'Salmon' kills 15 and hospitalises 115
You've got to be a little bit mad to dine on a fish like fugu that can potentially kill you. However, even eating what you believe to be salmon can be potentially deadly.
Fish suppliers in Thailand aren't legally allowed to sell puffer fish meat, as it was banned there in 2002, so some of them have been dyeing the toxic puffer fish meat and passing it off as salmon on fish markets and restaurants to unsuspecting punters.
In the space of three years, 115 people were hospitalised after eating the puffer fish meat (which is known as fugu) and 15 were left dead. The meat contains a toxin called tetrodotoxin (TTX) which is produced by bacteria living within the fish. Miniscule quantities can be deadly and there's no antidote.
However, an active part of TTX is also a pain killer some 3000 times stronger than morphine and this is being used to produce a new drug called Tetrodin to help addicts come off heroin.

Diver impaled by four-foot needlefish
In 2005, 19-year old Tonga Loumouli from Hawaii was impaled through the chest by a pointy-nosed fish while diving at night. The fish stuck its nose in his chest and then wriggle free, leaving a massive gash and one of its teeth behind.Loumouli's friend pulled him into a dinghy and then dragged him a mile before getting help from a police officer. He was taken to hospital with a serious liver injury. While in hospital, unable to speak and attached to a ventilator he scribbled a note to his mum and sister which read "I'm going to quit diving..."

Boy collapses after being stung by fish
You're not even safe if you're in the UK. One youngster, 13 year old Aaron Maughan, who was paddling in the sea at Seaton Carew in the north east of England, collapsed after he stepped on a venomous Lesser weever fish, Echiichthys vipera. This small fish, which reaches up to 15cm/6" in length, tends to spend much of its time sitting buried in the sand with only its small poison-laden dorsal fin spines sticking out.Maughan said: "I'm a blackbelt in karate and have had a lot of fights, even a broken nose, but this was something else. It felt like I had stood on a nail or glass. I looked down and there were three spikes sticking out of my foot. I started to walk back to my gran up the beach, blood was dripping out, then I just collapsed."

Fishkeeper poisoned by dead fish
The fish don't even have to be alive to cause problems. The curator of a public aquarium in the Netherlands got pricked by a dead porcupine puffer while conducting an autopsy on the fish and ended up getting poisoned.A number of pricks from the spines of the pufferfish allowed the fish's body fluids, which contain the potent neurotoxin tetrodotoxin, get into his system. He survived, but suffered from paresis (a loss of movement of the limbs), paresthesias (loss of sensation), as well as a headache, dizziness and numbness.

Man attacked with stuffed fish
Nor do the fish have to be freshly dead. An American woman used a stuffed swordfish to attack her boyfriend during an argument, leaving him with several cuts to his arms and shoulders. Ouch.More: Man attacked with stuffed fish

Piranha bites off side of man's finger
Although widely believed to be one of the most dangerous fish, according to recent research piranhas aren't usually that dangerous, unless you catch them.However, fishkeeper Mike Rizzo of Michigan suffered a nasty wound when he was moving his pet sub-adult Diamond rhombeus piranha to a new aquarium. The piranha, which is called Markov, tried to jump out of the net on the way to the new tank so Rizzo put out his hand in an attempt to block it. Unfortunately, the startled fish chomped straight into his finger, ripping off the side.
Rizzo told Practical Fishkeeping: "He got a hold of my finger damn well. He bit all the way down into my knuckle and broke the capsule my knuckle is in and chipped a piece of bone off it. The bite also went through the nerves and other stuff in my finger. At first it was extremely painful. I think that a lot of it was due to the initial shock as well as seeing the skin and flesh dangling off and seeing blood literally spurting out as my heat beat, and just forming a large pool on the floor."

Woman badly bitten by piranhas
If you're leaving your piranhas in the care of your mum, you'd think it would be a good idea to let her know what she was dealing with. However, one mother wasn't quite so lucky and suffered a nasty wound after one of her son's "goldfish" latched on to her hand while she was cleaning out its aquarium. Doctors said she lost all of the skin from two of her fingers and was lucky not to have lost her hand in the incident.More: Woman badly bitten by piranhas
Statistician stung by scorpion fish
A British man who works for the Office for National Statistics was stung by a scorpion fish and nearly died while on holiday on the Greek Island of Rhodes. What are the chances of that happening?Rod Lawson from Cumbria picked the fish up and got speared in the finger, then got jabbed again as he was putting it back in the sea. Lawson said: "[My arm] was like an elephant's trunk - four times its original size from the fingers right up to the armpit. It looked absolutely terrifying. It was very, very scary because the pain was intense and within just a short space of time I was drifting in and out of consciousness. Apparently it was touch and go for quite some time."

Woman killed by leaping eagle ray
Spotted eagle rays, Aetobatus narinari, which can reach several metres across, don't jump out of the sea that often, so Judy Kay Zagorksi of Michigan was exceptionally unfortunate to have been hit by a 1.5m wide specimen earlier this year.The massive ray leapt from the sea and collided with Zagorski while she was in a boat with her family off the Florida Keys. Although the species is potentially venomous, it's thought that the weight of the fish hitting Zagorski was the cause of death in this bizarre accident.

600lb Marlin "attacks" angler
An 18-year old angler on a game fishing trip off Panama was attacked by a massive 600lb Marlin after it jumped into the boat he was fishing from. Stephen Schultz was knocked to the floor and had blood pouring from his nose and mouth.He was flown to hospital were x-rays showed that his sinus walls had been broken in four places. He also suffered an inch and a half cut in the back of his throat and had numerous lacerations inside his cheeks after the Marlin's sword smacked him in the face. The Marlin was returned alive.

Man impaled by giant fish
Ian Card was less lucky. He was fishing in an International big game fishing tournament off Bermuda when he hooked a 14' Blue marlin, Makaira nigricans. The fish, which weighed around 360kg/800lb leapt out of the water, impaled him through the chest with its 90cm/3' long sword and jumped into the sea with him still attached.The fish swam down deeper, but miraculously, Card managed to push himself off the sword and resurfaced 50m from the boat with blood pouring out of his chest. Amazingly, he survived.

Girl critically ill after eel jumps into mouth
A three-year old girl in Taiwan became critically ill after a bizarre incident involving some live eels. Her father caught a number of eels and took them home alive to cook them. While he was killing one of the eels it made a bid for freedom and jumped into the girl's mouth, where it became lodged in her oesophagus.Her father managed to pull the fish free, but ruptured her oesophagus in the process, resulting in surgery to fix the wounds, as well as a secondary infection.

Puffer fish kills eight and hospitalises 170
In a single week, eight people were killed by eating toxic puffer fish meat, while another 170 were hospitalised and survived. Cats, dogs and crows who ate the scraps also died.140 of the people went down with puffer fish poisoning after eating a fish ball soup at a funeral in Thailand. After the meal, the guests started to vomit and were complaining of numbness of the tongue and shortness of breath. A single puffer fish contains enough toxin to kill 30 people, and there's no antidote.

"Speaking as someone who has experienced bad cuts from bass, perch, and even from the gill rakers of a flounder as I carefully returned it, I think this speaks volumes about care and compassion when handling any fish and the importance of knowing plenty about the local wildlife and any fish that you keep or are considering keeping.
Even the defence mechanisms of smaller fish are there to stop them getting eaten, that is bodily swallowed, so it's no wonder they can deal with a couple of fingers wrapped around them..."

"I suppose there is a degree of what some would call karma here. People reeling in a 600lb fish, a fairly unpleasant hook in it's mouth, struggling, not for sport, but from fear, from pain at the very least, will struggle to survive. The implication that these people (and I speak specifically to those cases of fishing in general, and not to obvious accidents), are somehow victims is preposterous in the extreme. Quite honestly, it is nothing short of a very minor victory for these fish, despite the fact that, unlike humans, they did not seek to maim with concious malice, but only to live.

"Just to add to the fish "horror stories"
Last August I came home from work and gazed into my 6ft tropical aquarium, as you do! I was thoroughly annoyed to see the larger of my 2 sorubim lima shovelnose catfish half way through dining on my very large ghost knife fish. Half of the knife fish was still hanging out of the fish but was almost certainly dead. I didnt want the lima to choke on it and die because it was stuck so decided I had to remove the fish from its mouth. I opened the lid of the aquarium and proceeded to herd the catfish into one corner with my right hand so that I could then net the fish and transfer it into a large bucket.
Before I could get the net close to it the shovelnose had flipped and body slammed me in the hand. I was in immense pain and although I didnt realise it at the time it had stuck it's pectoral fin into me which had then snapped off and proceeded to travel through into the palm of my hand. I was in incredible pain but decided I had no choice but to drive to hospital with my hand inflaming more and more by the minute.
Once I arrived at hospital and had waited in A&E for 2 excruciating hours I was given an X-Ray. The doctor said that there was nothing present on the X-Rays. I insisted to look at the scans and could clearly see the spine further down in my hand, around 2" away from the entrance wound. The doctor was astounded and they instantly took me up to the ward and insisted that I had to stay the night and would have to have my hand operated on the next day.
The following morning i was dosed up with some rather lovely pain relief medication and into surgery I went. They put me under a general anesthetic as the surgery was quite complicated as they had to negotiate all the nerves, tendons, muscles etc in my hand to remove the fish's pectoral spine but also clean the entire entrance wound.
I am now left with a scar starting on my index finger and stretching back to the middle of the back of my hand. To this day it is still numb although thankfully has not restricted my hand's movement or dexterity!

"Hello,
yesterday, on an Algarve beach two boys were stung by a Portuguese warship. They have mistaken it for a inflatable toy floating very near the sand. They both were hospitalised, with severe skin injuries, one of them is still in intensive care but out of danger. The hospital where they were taken had to contact the Central for toxic injuries because they did not know the antivenom that they had to administer. I suppose its not often that something like this happens, although it's a jellyfish that is endemedic of our coast."

"Hello Matt and Nicola,
Superb article. I teach epidemiology, environmental issues and foodborne illness at the University of Salford and would like to use your article as a handout. Would you please give permission to do so? The article would be photocopied and all references and acknowledgements would, of course, be included.
As for fish, my life is ruled by two goldfish who don't like to be ignored. They like being stroked, fed and watching the monitor. They have found a great trick to get attention if you ignore them. They come to the edge of the tank and suddenly dive. The resulting plume splashes water on the keyboard and guarantees that you stop typing and take an interest in them.
Best regards
Chris"

"I did not know of the existence of the weever fish until one day, on a day trip to a beach, a person near me was stung by one.
They were in absolute agony and I ended up calling an amblulance. However the life guards on the beach knew exactly what do do.
I would like to see more widely held information about this fish along with first aid methods for those who are unfortunate enough to be stung
I still occasionally go into the sea without flip flops, but not in such a carefree manner as I used to...

"Hi all
Reading all these stories of people being killed or injured by fish reminded me of an incident that happened to me in 1984 whilst working on a deep sea trawler in the bay of Biscay.
Whilst gutting monk fish I slipped and some how managed to get the fish I was gutting hooked onto the inside of my lower lip.
It was removed by the Skipper and as we were at sea for another 15 days I was treated with antibiotics.
A case of the Fish bites back methinks, I can still feel the row of lumps left by the teeth to this day, on the same trip I also managed to get two large eating crabs one on each thumb, the first nipping me as I went to pick it up, the second as I put my weight onto the fish table in an attempt to shake the first off.
Hence me keeping Koi a much safer option I believe lol."
