  • The second word is the species name, written in italicized, lowercase letters

Scientific Names

  • Scientific names are derived from Latin
  • This helps scientists from different countries to understand each other
  • Common names for a species vary from country to country
  • This use of Latin words avoids confusion among scientists from different nationalities
