Which Species Are Close to Extinction?

It's no mystery—humans pose the greatest threat to many of Earth’s species. Habitat encroachment or destruction, an increase in the severity of weather events (hurricanes, flooding, fires, etc.), poaching (the black market—fur trade, ivory trade, medicine, delicacies, etc.), and our fossil fuel dependency (including use for agriculture) are some contributing factors.

If you are living in this 21st century, you already know that many of today's species are currently vulnerable, threatened, or endangered.

As of 2020, there are only 2 white rhinos left in the world. The last male died in captivity.

Here we will take a look at:

  • Whales
  • Whale Sharks
  • Elephants
  • Tigers
  • Gorillas
  • Rhinos
  • Dolphins
  • Sea Turtles
  • Leopards
  • Red Pandas
  • Pangolins
  • Orangutans

International vs. Regional Populations

In 1964, The International Union for Conservation of Nature’s Red List of Threatened Species became an incredibly useful resource for gathering information about the status of species—animal, fungi, and plants—internationally. You can find valuable information on the IUCN website regarding the current status of most species. Keep in mind, however, that populations differ by region. A threatened population in one area of a country may be endangered in another. So, which species are currently close to extinction? Let's take a look.

What Does It Mean When a Population Goes Extinct?

Dictionary.com defines extinction as: "—the state or process of a species, family, or larger group being or becoming extinct." Extinction essentially means to disappear. It can happen to a species entirely, meaning that all species are lost (wild and in captivity). Or, extinction might refer to wild populations. Often, in efforts to conserve or save a species, all wild ancestors will be extinct but a critically endangered species may be raised in captivity in an effort to save the population.

How Many Whales Are Left?

Species

  • Blue whale (Balaenoptera musculus) endangered

The fin whale comes in as the second largest mammal in the world. Fin whales (65-80 feet; 80 tons) can be distinguished from other whale species by their "razorback" appearance—a ridge behind their dorsal fin. Fin whale populations currently number between 50,000-90,000. They are found in the waters of California and the Arctic.

North Atlantic Right Whale

Only 300-350 right whales remain. They can weigh up to 70 tons and reach 45-55 feet in length. They inhabit the Atlantic and areas near Iceland, Greenland, and the UK. They feed primarily on plankton.

Bengal Tigers

The Bengal tiger is the most numerous of all tiger species. They are primarily found in India, but there are only 2,500 currently left in the wild. Their habitat, the Sundarbans, are currently disappearing due to rising sea levels.

Less than 400 Sumatran tigers of Indonesia exist in the wild. They face deforestation (habitat loss) and poaching and loss of prey. They are especially wanted for their fur, teeth, claws, and meats/organs for believed medicinal properties.

Alexander—I agree. I love these amazing creatures. We spend so much time trying to replicate their natural gifts—sonar, flight, etc. Beautiful.
