The man eating pomfret is native to the Amazon River basin in South America. Currently distributed in countries such as Brazil, Argentina, Bolivia, Colombia, Paraguay, etc. Feed on small fish, shrimp, amphibians, aquatic invertebrates, etc. The man eating pomfret is a high-risk invasive species, and once it establishes a population in an invasive area, it becomes a top animal in the water food chain, strongly occupying the habitat of native aquatic animals. In order to prevent ecological disasters caused by "biological invasion", relevant departments in China have banned its imports, controlled its breeding in professional and research institutions, and prohibited its circulation in the market.
