Abstract. The northern snakehead (Channa argus) is a large piscivorous fish that is invasive in eastern Europe and has recently been introduced in North America.n the winter (NovemberâApril), these fish moved to deeper water (~135 cm) with warmer temperatures, but habitat selection was weak at both scales. Northern snakeheads returned to shallower water (~95 cm) in the prespawn season (AprilâJune) and used milfoil and other cover.
A large, social venomous snake, the northern copperhead ranges across the eastern half of the United States. They live in habitats ranging from terrestrial to semi-aquatic. Even just-hatched copperheads have fully functional fangs capable of injecting venom. These hatchlings have venom that is just as toxic as adults' venom. The copperhead is the cause of many snakebites yearly but they are rarely fatal. Bites occur by accidentally stepping on or touching the snake, which tends to be well camouflaged with its surroundings.
