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]
List of dangerous snakes The Inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD50 value of 0.025 mg/kg SC.[6][90] Ernst and Zug et al. 1996 list a value of 0.01 mg/kg SC, which makes it the most venomous snake in the world in their study too. They have an average venom yield of 44 mg.[90] Bites from this species have a mortality rate of 80% if left untreated, although it is very rare for this species to bite. This species is known to be a very shy, reclusive and a laid-back snake that will nearly always slither away from disturbance. It is not an aggressive species and rarely strikes. No recorded incidents have been fatal since the advent of the monovalent (specific) antivenom therapy.
