El Cuero, meaning "cowhide" or "leather" resembles a primitive stingray at most. It has wide pectoral fins and a long, whip-like tail, absent of a barb. Its eyes are on stalks and its mouth is apparently extendable, like that of a sturgeon. Eyewitness have also reported seeing a serious of razor sharp claws along the fringes of El Cuero, which the creature uses to secure its prey. There have also been suggestions that El Cuero uses hunting knives taken from previous prey as weapons against new victims. The size of El Cuero ranges from 2-5 feet across and approximately 65 pounds. Although El Cuero may be distantly related to the family of freshwater stingrays known as the Stenohaline which call South America home, there are some notable differences between South America’s freshwater stingrays and El Cuero.
El Cuero apparently hunts in the Chilean glacial Lake Lacar, which is located in the Andes Mountains.
Attacks on Humans
South American natives constantly tell that El Cuero is a voracious predator, giving it the nickname "aquatic tiger." The monster apparently surges out of the lake, like an orca, and overwhelms its prey (humans). It then uses its proboscis to puncture the skin and suck internal organs and blood.
There have been countless, yet controversial, attacks on humans. One story tells of a woman washing clothes by the lakeside; her baby slept nearby. According to her, the creature burst from the water like a crocodile and engulfed the baby. It then slipped into the water as quickly as it appeared.
Similar creatures to El Cuero have been reported to dwell in the rivers and lagoons of both Argentina and Chile, and the legend of El Cuero has circulated throughout the ingenious populations of these two nations. Some Investigators have pointed out the similarities between this animal and the vicious Hueke-Hueke, another South American lake cryptid. So similar are the reports of these two creatures that many researchers suggest that the creatures are actually the same animal.
South American mothers warn their children to stay away from lakesides, fearing "Hueke Hueke" will eat them.
