Goliath Tigerfish

The Goliath Tigerfish, found exclusively in Africa's Congo River Basin, holds a supernatural status locally due to its vicious nature. Legends describe it as being possessed by an evil spirit, striking fear into those who approach. According to Congolese culture, encountering this fish at the start of a voyage brings terrible luck. Known for its menacing appearance and lethal, eagle-tall and sized teeth resembling spiked taggers, it can grow as large as a human and boasts a bite stronger than a person's. This fearsome reputation makes it unpopular among anglers and notorious for injuring those who attempt to catch it.

Large Tooth Sawfish

The sawfish is a remarkable ray with a chainsaw like snout, among the world's most unique biological marvels. Growing up to 20 feet long and living up to 35 years, it's a formidable predator, resembling a miniature shark. Known as a rostrum, its snout serves two crucial purposes, hunting and detecting electric fields. Thousands of tiny organs enable it to sense the electric fields emitted by living organisms, functioning as its sixth sense. This adaptation allows the sawfish to navigate and hunt without relying on sound or sight. The rostrum also aids in hunting by sawing prey into digestible pieces and defending against predators like sharks and crocodiles.

Nile Crocodile

The 20-foot aquatic creature is notorious as one of the most lethal crocodilians, attacking over 200 people annually in South Africa. In 2019, near the Botswana-Zimbabwe border, Mavis was heading to a nearby church. Around 7 p.m., while crossing the Lepel River, she was dragged back by a crocodile. Friends intervened, one attempting to poke its eye with a stick. Although Mavis survived the initial attack, she succumbed to severe injuries after five days of treatment. Authorities suspect an aisle crocodile was responsible, adding to its toll of 48 fatalities before Mavis in recent years.

The White River Monster

Since 1915, Arkansas has been intrigued by a local legend known as Whitey, or the White River Monster. Believed to lurk in the depths of the White River, this creature remains unconfirmed but widely believed in by residents, leading to legislative protections against hunting or harming it. According to Corpore Indians, the monster, resembling a snake and possibly 30 feet long with a spiny backbone, allegedly overturned a warrior's canoe before disappearing. Outcomings continued into 1937, when a farmer claimed regular afternoon appearances. Despite speculation that it may have perished due to shallow waters, the existence of the White River Monster remains unproven.

The Florida Arapaima

Florida Beachgoers recently found a lifeless river monster, sparking concerns about its potential as an invasive species. Authorities fear the Arapaima, a massive Amazonian fish up to 14 feet long and weighing 440 pounds, could breed in Florida waters. However, aquatic ecologist Solomon David reassures that breeding is unlikely due to specific environmental needs. He suggests the found specimen was likely an exotic pet released into the wild, a few are imported annually for aquariums. Arapaima are conditional pets in Florida. Their unchecked population could pose serious risks due to their voracious appetite and powerful swimming ability, potentially lethal to humans.

Radiation Catfish

Giant catfish inhabit the infamous Chernobyl power plant, site of the 1986 disaster. Initially thought to be mutated due to radiation leaks, studies later showed these Vels catfish naturally grow to enormous sizes. Radiation specialist Dr. Timothy Mosso clarified that radiation typically causes different mutations, not giant growth. When Jeremy Wade of River Monsters found a catfish 16 times more radiated than normal, it raised concerns, but experts concluded it wasn't alarming. Vels catfish can reach up to 800 pounds, though they typically weigh around 350 pounds. Despite their size, they are not known to pose a threat to humans.
