News of a particularly unfriendly species of fish - known colloquially as "frankenfish" - being spotted in a Pennsylvania county has sparked concern among officials that the voracious predators could disrupt the local ecology.
The northern snakehead is an aggressive species that typically eats other fish. Nicknamed the
"frankenfish," the invasive species could wreak havoc on the environment if it's allowed to spread, according to a
fact sheet on the species authored by the US Geological Survey.
"Should snakeheads become established in North American ecosystems, their predatory behavior could drastically disrupt food webs and ecological conditions, thus forever changing native aquatic systems by modifying the array of native species," the agency wrote of the bloodthirsty fish.
The cannibalistic ecology-wrecker has no lack of scary features. For one, it is said to be able to
"walk" on land - although it's actually more like wriggling or snake-like slithering and it mostly does so to get back to water, not to crawl into your house and murder you while you sleep.
