The giant snakefish
In 2002, the snakefish (or Channidae) was described as “something from a bad horror movie” by US Interior Secretary Gale Norton.
Some describe snakefish as having ”a voracious appetite, often consuming all other fish in a lake or pond and even eating its young. It can slither across land, staying out of water for up to three days, to find new sources of food.”
Norton also warns that once on land ”snakeheads can eat almost any small animal in its path…. They have even attacked people in China who got too close to snakeheads’ egg nesting areas.” According to Wikipedia, snakefish can be up to over a metre in length and over 6 kilograms in weight.
Most snakefish are 2-3 feet long. They’re also fast reproducers with no natural enemies outside of their native environments. Within their native environments, small snakefish are preyed upon by bigger fish, while full-grown snakefish are consumed by crocodiles and alligators.
Because of their ability to move into new habitats and wipe out local ecosystems (and to cross from one body of water to another and repeat the process) snakefish have been prohibited in 13 American states and other countries (e.g. Australia).
