Northern snakehead fish are non-native to the US, but recently a fisherman caught the northern snakehead fish in a pond in Maryland. It is suspected that live fish were intentionally released to the pond. This fish is considered a delicacy in some cultures. Snakeheads are top predators, with 90% of their diet being other fishes. These snakeheads can breathe out of water and travel short distances (about 100 feet) across land. Females can lay more than 100,000 eggs per year. Juveniles have been identified in nearby rivers, such as the Potomac. Based on the information provided, what classification and description best details the impact of this species in Maryland freshwater ecosystems? A) Snakeheads are keystone species and will increase biodiversity.
B) Snakeheads are invasive species and will decrease biodiversity in local ponds.
C) Snakeheads are primary producers and will improve the water quality of local ponds.
D) Snakeheads are primary consumers and will decrease the producer biomass in local ponds.
