All organisms including animals have both common and scientific names.

The first word in a scientific name is always capitalized. The second word is not capitalized. The whole scientific name is either underlined or italicized
Examples:
Lion = Panthera leo or Panthera leo
pine tree = Pinus storbus or Pinus storbus
