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.
The northern copperhead is a pit-viper, as are all three of Virginia's venomous snake species (northern copperhead, eastern cottonmouth and timber rattlesnake). The pit in pit-viper refers to the heating sensing pit located between the eye and the nostrils on the snake's head.opperheads are born alive and with the exception of the tail tip, they are colored and patterned the same as adults. The following four photographs are of baby/juvenile northern copperheads. Note the sulfur yellow colored tail tip. The yellow tail tip is used as a lure for frogs, lizards and other prey items.
