Metlapilcoatus borealis is a species of jumping pit viper endemic to Mexico, named after the northernmost section of its distribution.[1][2][3] Like all pit vipers, it is venomous.[4]
Description
M. borealis is a medium-sized snake, measuring up to 66cm in males and 60cm in females. Its specific scale count can also help identification, with 22-25 rows of scales over its middle, 4-6 nasorostral scales, 130-132 ventral scales, 26-35 subcaudals, 8-10 supraoculars and 2-3 interoculabials. Genetically it can also be distinguished by three unique nucleotide sequences.[4]
