Origin
Channa marulius is native to South and Southeastern Asia. Bullseye snakehead were likely introduced to the United States as a food source for human consumption.

Life Cycle
Morphologically similar to native North American Bowfin (Amia calva), the two species are often confused. C. marulius is distinguishable by having a longer anal fin than A. calva. Additionally, the placement of its pelvic fin is almost directly below the pectoral fin whereas the pelvic fin of A. calva is in the belly region. Bullseye snakehead are approximately 47 in. (120 cm) in length. Bullseye snakeheads display parental care until young are approximately 3.9 in. (10 cm) in length. C. marulius are predatory with fish and crustaceans making up most of its diet. Bullseye snakeheads prefer deep clear lakes and rivers with rocky or sandy substrate.

Distribution
C. marulius is established in Florida.

Control Efforts
The effects of C. marulius introduction is unknown, but it has the potential to impact native fish and crustacean populations.
