Question

Blue whale is placed under:
A. Endangered
B. Critically endargered
C. Rare
D. Extinct

Answer 1

Hint: A species can be any type of living thing, including mammals, trees, coral, fungi, insects, sponges, and coral.
They may live virtually their whole lives in midair, near boiling water, sulphurous sludge, frigid wastelands, underground rivers, prickly woods, and hazardous cliffs.


Complete step by step solution:
The red list, which includes 16,118 endangered species, is maintained by the IUCN.

Species that are officially categorized as Critically Endangered (CR), Endangered (EN), or Vulnerable are considered threatened (VU).

In real terms, this means:
A species that is critically endangered (CR) is one that has a very high chance of going extinct in the wild.
An endangered species (EN) is one that is thought to be in extremely high danger of going extinct in the wild.
A species deemed vulnerable (VU) is one that is thought to be very susceptible to extinction in the wild.

The blue whale (Balaenoptera musculus) is a marine animal that is a member of the Mysticeti suborder of baleen whales. It is the largest animal known to have ever existed, measuring a maximum confirmed length of 29.9 metres (98 feet) and a weight of 173 tonnes (190 tonnes). The blue whale is listed as threatened.

  Therefore option A is the correct answer, Endangered.

Note:
Since its creation in 1964, The International Union for Conservation of Nature's Red List of Threatened Species has grown to become the most thorough information resource on the state of animal, fungus, and plant species' global conservation.
Looking at the IUCN Red List can help one determine the current state of the world's biodiversity.. It is a powerful instrument to inform and spark action for biodiversity conservation and policy change, crucial to preserving the natural resources we need to survive, and is much more than a list of species and their status.
