Dawson (1982) noted that there are two distinct color patterns of this species with no definite intergrades. Some authors are of the opinion that these color extremes represent two different species and should this be true, Dawson stated that Kaup's vittatus has priority over ensenadae with AMNH 7792 documenting the Bermuda occurrence of Micrognathus vittatus.Conservation status (IUCN)Not EvaluatedThreat to humansHarmlessResilienceHigh, minimum population doubling time less than 15 months (Preliminary K or Fecundity.)
