10 of the World’s Most Dangerous Fish

Many people around the world depend on fishes or products made from fishes for their food and economic livelihood. More than 30,000 different species ply Earth’s oceans and bodies of fresh water. The beauty of many fish species is highlighted in fish stores, aquariums, and in home collections. Some species, however, have darker, more terrifying aspects. A select few of these may attack human beings, while others might deliver a dose of poison when handled carelessly or not properly prepared for consumption. Some species are maligned due to their shocking appearance or by their ferocious reputation in folklore and myth; however, one species, though cute and tiny, threatens bathers in a very, shall we say, personal way.

Rare Fish Called the ‘Nutcracker’ Eats Mens Testicles with Human Like Teeth, Caught in New Jersey Lake

A father and son fishing at a New Jersey lake may be lucky their bodies still have all their pieces after catching a fish called 'the Nutcracker' that is more commonly seen in the Amazon.

Ron Rossi, from the Philadelphia suburb of Delran, was out with his son Frank at a man-made body of water when they hooked what they thought was a piranha.

However, the rare species in Swedes Lake was actually a pacu, an omnivorous fish native to Brazil that has human-like teeth and has been reported to eat the testicles of swimmers and fishermen.

The Rossis realized the bizarre find when they went home and researched the animal after being confused at its lack of sharp, piranha chompers, they told WPVI.

Department of Environmental Protection officials said the South American fish are sometimes kept as pets, who may have dumped the pacu into the lake.

The species can grow up to four feet long and uses its molar-like teeth to crush food that falls into the Amazon River.

Many pet owners mistakenly think they are piranhas when they purchase the more famous species's cousin, which can grow up to 55lbs.

Given the fish's worldwide popularity, it turns out that the Rossis did not make the surprise catch of the century, or even of the last couple years.

A 10-inch pacu was caught in northern New Jersey in September 2013, followed by 17-incher in Washington state, a 20-inch specimen in southern Illinois two months later and a 14-inch pacu in Michigan's Lake St Clair last summer.

The fish's worldwide popularity has seen them spread far from their Brazilian homeland, with the fish being found in Paris, Scandinavia and Oceania.

In Papua New Guinea, where the fish is known as the 'Ball Cutter', a member of the species is thought to have contributed to two men's death from blood loss after it castrated them.

Scientists in Denmark said that reports of pacu eating genitalia were 'overblown' after they issued a joking warning to male swimmers to beware following a sighting of the fish, according to National Geographic.

Some wildlife experts worry that the introduction of pacu into lakes such as the one in New Jersey may endanger local fauna.

However, pacu cannot survive in colder water and the DEP urged owners of the fish to 'humanely destroy' it rather than throwing it into nearby waters.

A New Jersey man was surprised when he thought he caught a piranha, but the fish turned out to be a pacu, an Amazonian fish famous for eating men's private parts.

The Swedes Lake catch was the latest in an increasing number of pacu being found outside of their native habitat.

Fisherman Ron Rossi (pictured) researched the animal with his son, and environmental officials said that it most likely came from a pet owner who dumped it in the man-made lake

Pacu have spread around the world from their tropical home and been captured in places in northern Europe such as Scandinavia. Above left, a fish captured in Paris was about a foot long

Piranhas Make Interesting Pets: Depending on the Species, Adult Piranhas Can be 12 -16 Inches Long

Piranhas can make interesting pets with their full sets of sharp teeth and their fast and furious attack skills. Keeping piranhas is a bigger commitment than keeping other fish as pets -- they require lots of space, and they can live more than 20 years in captivity. Meanwhile, their food and water temperature needs are rather simple to accommodate.

Room to Move
Piranhas can seem cute when they're small and hiding among tank decorations much of the day, but they don't stay small. Depending on the species, adult piranha can be 12 to 16 inches long. They come from river environments and live best in large tanks -- a 100-gallon tank suits a single adult piranha; add 20 gallons for each additional piranha. Red-bellied piranhas tend to school in the wild, so you can likely keep a few in the same tank, although they might attack each other at some point. If you're keeping a black piranha as a pet, house him alone -- he's just as likely to eat another piranha as the dinner you provide him.

Ringing the Dinner Bell
Piranhas aren't strictly carnivores, although meat is definitely their meal of choice. If you have aquatic plants in your tank, you might see your fish take a few bites here and there. They also eat fish pellets and flakes occasionally, and they can benefit from the vitamin boost these foods provide. But for most of their meals, plan on feeding protein such as krill, mealworms, earthworms or feeder fish. Unless you raise your own under controlled conditions, thaw frozen versions of these foods or buy live ones from reputable fish food suppliers. Avoid grabbing insects and worms from your yard -- they might have ingested chemicals such as pesticides and herbicides, which they can transfer to your piranha. Juvenile fish need to be fed up to four times per day, while sub-adults usually need food about twice a day. Feed mature adults about once every two days.

Home Sweet Tank
Piranhas can survive in a variety of tank conditions, but they prefer a water temperature of between 78 and 82 degrees Fahrenheit and a sandy substrate. Juveniles are especially fond of aquatic plants. In the wild, they spend much of their time hiding from predators until they reach their adult sizes. However, adults enjoy swimming among the plants as well. They also like large pieces of driftwood that offer secluded places to rest.

Keeping It on the Up and Up
Before buying a piranha for a pet, check with your local and state regulations. Many states ban piranhas because people sometimes release them into the wild; introducing non-native species can wreak havoc on your local environment. Non-native species can compete with indigenous ones for food, sometimes endangering the other species' survival. Also, state governments often don't want to risk local fisherman catching piranhas unexpectedly and potentially becoming injured. Even if you have no intention of releasing a pet piranha, always follow local regulations.

Safety First
Owning a piranha means taking a few precautions to ensure he doesn't decide your hand looks tasty for dinner. Even small, a piranha has razor-sharp teeth that can easily bite through your skin; as an adult, he can bite through bone to remove entire fingers. To prevent injury to yourself, never dip your hand in the water to feed a piranha. Also, don't place a hand with a wound, even a small scratch, in or near the top of the water -- the blood might attract the piranha, who swims powerfully enough to jump out of the water. Clean the tank with long tools instead of putting your arm inside, and use a net to catch your fish when it's necessary to move him. He can bite through the net, so don't stabilize him with your hand. Instead, hold a second net under the first to catch the fish if he bites a hole in the first net and falls through. FOLLOW US!

Arkansas Game and Fish Commission Authorities Confirm: Fish Caught by Fisherman is a Piranha

A fisherman caught a piranha while fishing on an Arkansas lake last week, Arkansas Game and Fish Commission authorities confirmed.

Roger Headley was fishing on Lake Bentonville Friday when he caught the toothy fish, which he thought was a large perch.

Headley told a television station the fish actually did try to bite him when caught.

“I knew he kind of looked funny, and when I reached down and tried to take the hook out of his mouth, that's when he opened up his mouth and tried to bite me,” he said.

The Arkansas Game and Fish Commission lists piranhas among species of exotic animals that are unlawful to import or transport.

Game and Fish experts told KHBS/KHOG-TV that piranhas, which usually are dumped by former pet owners, are not a threat because they don't last long in Arkansas' cold waters.

Headley said it was luck that the fish wasn't caught by a young child.

“If a little kid would have caught him or something he could have lost a finger or anything,” he said.
