Kingdom: Animalia (animals)

 Phylum: Chordata (vertebrates)

    Class: Mammalia (mammals)

      Order: Carnivora (carnivores)

      Suborder: Feliformia (cat-like)

Family: Felidae (cats)

Subfamily: Pantherinae (big cats)

Species: Panthera tigris (tiger)


P.t. tigris

P.t. sondaica

Note: The scientific name for the Tiger species, Panthera tigris, is also known as the binomial name, species name, latin name, biological name and zoological name. Some use the term 'botanical name' however that is only applicable to the plant kingdom (botany) and not the animal kingdom (zoology).

Subspecies (Lower Classifications)

Six extant Tiger subspecies (or lower classifications) were described in the Red List assessment in 2014 and three subspecies have already gone extinct:

Critically Endangered (CR)

  • South China Tiger Panthera tigris amoyensis
  • Malayan Tiger Panthera tigris jacksoni
  • Sumatran Tiger Panthera tigris sumatrae

Endangered (EN)

  • Amur / Siberian Tiger Panthera tigris altaica
  • Indochinese Tiger Panthera tigris corbetti
  • Bengal Tiger Panthera tigris tigris

Extinct (EX)

  • Bali Tiger Panthera tigris balica
  • Javan Tiger Panthera tigris sondaica
  • Caspian Tiger Panthera tigris virgata

However the last Felidae taxonomy revision in 2017 proposed only two subspecies of Tigers based on comprehensive genetic studies:

  1. Panthera tigris tigris - Mainland : larger size, paler coat with fewer stripes
  2. Panthera tigris sondaica - Sumatra : smaller size, darker coat with more stripes

*extant = still in existence

The 2022 assessment has discontinued the prior subspecies assessments and states that Tiger subspecies are still under review.

The global conservation status for Tigers is Endangered (EN) and populations continue to decline.

Tigers are the largest of all the wild cats, yet they are also the most endangered and some populations have already gone extinct. In spite of many conservation programs it is estimated the Tiger population has declined by over 95% in the past 100 years, primarily due to illicit poaching and habitat loss caused by ever increasing human populations.

The following global organizations are fighting to conserve our iconic Tigers:

Panthera.org - Tigers Forever

World Wildlife Fund WWF - Tigers TX2

Wildlife Conservation Society WCS Russia - Siberian Tiger

Wildlife Conservation Society WCS Russia - Amur Tiger

Please support these organizations with their important work if you can. No matter the size of your contribution, every bit helps!

Facts and Information

Besides being the largest of the big cats, Tigers have a unique coat pattern of only stripes. Other cats may have stripes on parts of their coats but their markings will also include spots, rosettes or blotches.
