The Seychelles wolf snake (Lycognathophis seychellensis) is a species of snake in the family Colubridae. It is monotypic within the genus Lycognathophis.[citation needed] The New Latin name, Lycognathophis, is derived from the Greek words λύκος (lykos) meaning "wolf", υνάθος (gnathos) meaning "jaw", and όψις (ophis) meaning "snake", referring to the snake's dentition.[5]
