  The maximum total length (including tail) recorded for B. pirajai is 137 cm (54 in). It is stocky and terrestrial.
  
  ## Geographic range
  
  Bothrops pirajai is found in Brazil in central and southern Bahia. Possibly, it may also occur in Minas Gerais. The type locality given is "Ilheos, Bahia, Brazil".
  
  ## Conservation status
  
  The species B. pirajai is classified as endangered on the IUCN Red List for the following criteria: A1c (v2.3, 1994). This means that it is facing a high risk of extinction in the wild in the medium-term future due to population reduction in the form of an observed, estimated, inferred or suspected reduction of at least 20% over the last 10 years or three generations, whichever is the longer, based on a decline in area of occupancy, extent of occurrence and/or quality of habitat.
  
  The rainforest inhabited by this species is unfortunately decreasing in area and quality, while becoming increasingly fragmented through deforestation. The areas that have been cleared are mainly being used for cocoa plantations.
