Description
editE. megalocephalus grows to a total length (including tail) of 54–62 cm (21–24 in), which is relatively large in comparison to other Echis species. The head is similar to that of E. pyramidum. Midbody, there are 31 rows of dorsal scales. The ventrals number 186–202, and the subcaudals 33–37. The color pattern varies, but generally consists of a series of pale, oblique, dorsal blotches set against a darker ground color.[2]
Geographic range
editE. megalocephalus is known only from the type locality, Nokra (Nocra) Island, which is part of the Dahlak Archipelago, off the coast of Eritrea in the Red Sea.[1]
