what kind of snake has a yellow band around its head
Ring-necked snake Its dorsal coloration is solid olive, brown, bluish-gray to smoky black, broken only by a distinct yellow, red, or yellow-orange neck band.[6][7] A few populations in New Mexico, Utah, and other distinct locations do not have the distinctive neck band.[6] Additionally, individuals may have reduced or partially colored neck bands that are hard to distinguish; coloration may also be more of a cream color rather than bright orange or red.[7] Head coloration tends to be slightly darker than the rest of the body, with tendencies to be blacker than grey or olive.[7] Ventrally, the snakes exhibit a yellow-orange to red coloration broken by crescent-shaped black spots along the margins.[6] Some individuals lack the distinct ventral coloration, but typically retain the black spotting.[7] Rarely, do individuals lack both the ventral and neck band coloration; so the use of those two characteristics is the simplest way to distinguish the species.[6]
Snakehead (fish) Snakeheads became a national news topic in the United States because of the appearance of Channa argus, commonly known as northern snakeheads, spawning in a Crofton, Maryland, pond in 2002.[8] Northern snakeheads became permanently established in the Potomac River around 2004;[10] and possibly established in Florida.[8] in approximately 120 miles (190Â km) of river, the population has surpassed 21,000 individuals.[11]
