Being a high level predator means that the giant snakehead eats many other fishes, amphibians and even small birds, but is not preyed upon by many other species. The giant snakehead is considered gregarious, with the young often following their mother closely. There have been reports of protective mother giant snakehead attacking men who have disturbed the snakehead's school of juveniles.The species has the ability to crawl onto land, where it can survive for up to four days.
The giant snakehead is found in Vietnam, Indonesia, Laos, Thailand, Malaysia, India, and possibly Myanmar. This fish can reach a length of 7 feet.
In 2002 and 2003, three specimens were caught in Maryland, all believed to have been released pets. In 2003, a giant snakehead was caught in Rock River, Wisconsin. . Biologists were concerned that warmwater effluents could allow the tropical species to survive in the colder climate.
In 2008 , a specimenof C. micropeltes was caught by an angler while fishing for pike on the River Witham in Lincolnshire, England. It is not clear if the species is breeding in the wild, or if this was an escaped captive specimen; a source within the Environment Agency was quoted as saying “The reaction was, 'Oh s***'. This is the ultimate invasive species — if it starts breeding here it's a disaster."http://www.outdoorcentral.com/mc/pr/03/09/24c6.asp
