The US state of Louisiana is facing a very serious, scary threat. Swamp rats.
These rodents weigh a hefty 10 kilos, hail from South America and are eating up coastal wetlands.
The fight against these beasts has been documented in a film aptly titled Rodents of Unusual Size that'll be shown at the Doc Edge Festival in New Zealand this month.
To tell us more about it is the film's director, Quinn Costello.
