Researchers are quite surprised by a human-like teeth fish which was found in Petaluma Pond, San Francisco. It is believed that this species is somehow related to piranhas.
Besides wondering how the fish ended up there, scientists are fascinated by its teeth which appear as if they were human teeth. The official name of the fish is Pacu, and it was caught by angler Juan Gallo while he was fishing at Lucchesi Park.
Fortunately, the fisherman managed to prevent the marine animal from escaping and decided to donate it to the state Department of Fish and Wildlife for further research. More than being a human-like teeth fish, its appearance was also very unusual, according to Gallo. Plus, he confessed that he had never seen such a fish in his entire life.
The Pacu fish originates from the freshwater of the Amazon River. Furthermore, as mentioned before, it is associated with the terrifying piranhas. Even if they are illegal in The Golden State, the human-like teeth fish were sometimes sold as exotic pets.
Nevertheless, it is not the first time someone catches a Pacu fish because another fisherman caught a specimen in Roberts Lake, Rohnert Park last year in June. Besides its unusual appearance, the Pacu has a bad reputation in the Amazon being known as a testicle eater of male swimmers. Its reputation spread after this idea (it might not be true) was presented in an episode of River Monsters, broadcasted in 2011 on Animal Planet.
According to the show presenter, Jeremy Wade, two men died of bleeding after their testicles were eaten by the fish. Plus, the area is dirty and hot, so people and their children usually go to the water to swim or take a bath being completely oblivious to the danger represented by this unusual fish.
Invasive species are known to cause an imbalance in the ecosystem. In Florida Nile crocodiles and Burmese pythons were reported as a possible danger. It was established that around 98 percent of the opossum population and 99 percent of raccoon population from south Florida were wiped out because of invasive species.
Plus, the Great Lakes were invaded by a massive population of golden carp, known as goldfish, and the Asian carp. Fortunately, the golden harp turned out to be one of the few invasive species that helped the ecosystem whereas the Asian carp was a pest. Hopefully, the human-like teeth fish won’t become one of the new invasive species.
