Answer View answer β–Ύ

Answer: Option B β€” Australia

Detailed Solution

The koala is native to Australia and is found in the wild only in eastern and south-eastern Australia.

About the koala:

Its scientific name is "Phascolarctos cinereus".

Although often called the "koala bear", it is not a bear. It is a marsupial, an animal whose young are born very small and develop in the mother's pouch.

A newborn koala, called a "joey", is about the size of a jelly bean. It lives in its mother's pouch for about six months.

It lives in eucalyptus forests and woodlands of Queensland, New South Wales, Victoria and South Australia.

It feeds almost only on eucalyptus leaves, which are low in nutrients and poisonous to most animals. Koalas have special gut bacteria to digest them.

Because its diet gives little energy, it sleeps or rests for about 18-22 hours a day.

The name "koala" is believed to come from an Aboriginal word meaning "no water", because koalas get most of their water from leaves.

It has fingerprints very similar to human fingerprints.

Conservation status:

  • In 2022, the Australian government listed koalas in Queensland, New South Wales and the Australian Capital Territory as "Endangered".
  • Threats include loss of habitat due to land clearing, bushfires (the 2019-2020 bushfires killed many koalas), drought, disease (chlamydia), dog attacks and road accidents.

Other marsupials of Australia:

  • Kangaroo: the national animal of Australia (along with the emu on the coat of arms).
  • Wallaby, wombat, Tasmanian devil, possum and quokka.
  • Australia also has two egg-laying mammals ("monotremes"): the platypus and the echidna.

About Australia:

  • It is the smallest continent and the sixth-largest country by area.
  • Its capital is Canberra, and its largest city is Sydney.
  • It is called the "Land of Kangaroos" and the "Island Continent".
  • India and Australia are members of the Quad, and signed the "Economic Cooperation and Trade Agreement" (ECTA) in 2022.

Animals unique to other regions:

  • New Zealand: kiwi (flightless bird) and tuatara.
  • Madagascar: lemurs.
  • South America: sloths, anteaters and llamas.
  • China: giant panda.

Why not the other options?

  • βœ—New Zealand has no native land mammals except bats; it is famous for the kiwi bird.
  • βœ—South Africa has animals such as lions, giraffes and springboks, but no koalas.
  • βœ—Indonesia has orangutans and Komodo dragons, but no koalas.

Quick tip

Remember: koala = Australia (marsupial, not a bear; eats eucalyptus; sleeps up to 22 hours; "Endangered" in parts of eastern Australia since 2022); kiwi = New Zealand; lemurs = Madagascar; platypus and echidna = egg-laying mammals.

Biodiversity, National Parks & Wildlife β€” Preparation

This question tests your understanding of Biodiversity, National Parks & Wildlife, a key topic in the General Knowledge section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.

This topic covers biodiversity and its conservation: biodiversity hotspots, endangered and endemic species, the IUCN Red List, in-situ and ex-situ conservation, India's national parks, wildlife sanctuaries, tiger reserves and biosphere reserves, and wildlife conservation projects. Questions commonly ask in which state a national park is located and which animal it is known for (Kaziranga in Assam for the one-horned rhinoceros, and Gir in Gujarat for the Asiatic lion), when Project Tiger began (1973), and which regions of India are biodiversity hotspots. The number of protected areas changes as new ones are declared, so check the latest lists. Practise the biodiversity and conservation questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
