Given the limited number of Biswamoyopterus in existence, no one knows the extent of their ranges. All of this information is transferred to a database to calculate the density of nutria across the Louisiana coast, and the LDWF combines these data with the results from the aerial surveys to determine the number of nutria remaining in the marshes and the amount of damage they are inflicting on the ecosystem. Subsequent ecological impacts led many states to implement eradication efforts. They are larger than muskrats and smaller than beaver. Capybaras live in grassy or marshy regions with water close by at all times, while nutrias create complicated burrows along riverbanks or ponds. Speaking of rats, nutrias look similar to beavers or rats, while capybaras have a stocky and very unique body shape.
