Endangered Species | Animals

The conservation status of a species indicates the species’ likelihood of becoming extinct. An endangered species is very likely to become extinct in the near future, either worldwide or in a particular jurisdiction. Endangered species are at risk due to factors like habitat loss, poaching, and invasive species.

The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species. In 2012 the IUCN Red List listed 3,079 animal species and 2,655 plant species as endangered. There are laws in many nations that protect conservation-reliant species like forbidding hunting and restricting land development.

How can we protect endangered species?

We can protect endangered species by learning more about the endangered species around our surrounding communities, minimizing the use of pesticides, and reducing our consumption of water within the home. Other ways to protect endangered species include recycling, not littering, and not purchasing products that are made from endangered animal species.

What is the most endangered species in the world?

The most endangered species in the world include the southern rockhopper penguin, snow leopard, savanna elephant, polar bear, and olive ridley turtle. Other endangered animal species are the marine iguana, loggerhead turtle, and hippopotamus. The greater one-horned rhino, greater white shark, giant tortoise, giant panda, and dugong are also considered endangered animal species.

Why are species endangered?

Animal species are endangered due to loss of habitat which happens either through human actions or naturally as well as loss of genetic variation. Other reasons for species being endangered include loss of genetic variation, which can sometimes occur naturally or happen due to human activity.

Red Panda (Ailurus fulgens)
Dimensioned comparison drawing of the Red Panda compared to similar Mustelid species

The Red Panda (Ailurus fulgens), also known as the Red Bear-Cat is a mammal known for its resemblance to a raccoon and excellent climbing skills. The Red Panda is covered by reddish-brown fur, has a long shaggy tail, and its 2 front legs are shorter than its back legs giving the Red Panda a waddle-like gait. The Red Panda is native to the eastern Himalayas and southwestern China. Typically, the Red Panda eats bamboo and at times birds, flowers, and berries. The Red Panda is considered in danger of extinction due to habitat loss.

The Red Panda has a body length in the range of 20”-25.2” (51-64 cm) and total weight of 8-17 lb (3.6-7.7 kg). Red Pandas have a shoulder height between 11”-13.4” (28-34 cm), body width of 5.5”-7.1” (14-18 cm), and tail length of 11”-19.7” (28-50 cm). The typical lifespan of the Red Panda is between 8-22 years.

Javan Rhinoceros (Rhinoceros sondaicus)
Dimensioned comparison drawing of the Javan Rhinoceros compared to simliar species of Rhinoceros

The Javan Rhinoceros (Rhinoceros sondaicus) shares a lot with the Indian rhinoceros, such as one horn, though much smaller, less apparent skin folds, and a smaller head. It is only males that have horns. The skin is dusky gray and is almost the same size as the black rhinoceros. It is also known as the lesser one-horned rhinoceros or Sunda rhinoceros. The Javan Rhinoceros is found in Java, India, China, and Sumatra. The upper lip is long and pointed, showing that it is a browser. It has a good sense of smell and hearing. Besides, it is a solitary animal except during breeding or mothers with calves.

Javan Rhinoceros' have a total body length between 9.8’-11.2’ (3-3.4 m), standing shoulder height of 4.9’-5.6’ (1.5-1.7 m), body width of 3’-3.3’ (.9-1 m), and typical weight in the range of 3,307-4,409 lb (1,500-2,000 kg). The horn of the Javan Rhinoceros has a length between 7.9”-9.8” (20-25 cm). Javan Rhinoceros' have lifespans between 30-45 years.

Black-Footed Ferret (Mustela nigripes)
Dimensioned comparison drawing of the Black-Footed Ferret compared to similar Mustelid species

The Black-Footed Ferret, Mustela nigripes, is a mustelid species native to North America; it is also known as the American polecat. Due to its small and restricted populations, it is listed as an endangered species by the IUCN. The main differentiation between the black-footed ferret and the European polecat, is the American polecat has a greater contrast between its dark limbs and pale body, and a shorter black tail-tip length. The species is largely nocturnal and solitary with exception of when breeding and raising litters. 91% of its diet is prairie dogs.

The Black-Footed Ferret has a body length in the range of 13”-18.1” (33-46 cm) and total weight of 1.3-3.1 lb (.6-1.4 kg). Black-Footed Ferrets have a shoulder height between 3.9”-5.9” (10-15 cm), body width of 2.6”-3.5” (6.5-9 cm), and tail length of 4.3”-5.1” (11-13 cm). The typical lifespan of the Black-Footed Ferret is between 4-9 years.

Green Sea Turtle (Chelonia mydas)
Size comparison drawing of the Green Sea Turtle compared to other turtles and a person

The Green Sea Turtle (Chelonia mydas) is one of the largest species of sea turtle in the world with a habitat range in both tropical and subtropical waters, distinct in both Atlantic and Pacific Oceans. Its common name is derived from the color of its skin rather than its shell, which is olive-brown. Aside from its color, the Green Sea Turtle is distinguished by its heart-shaped shell and its paddle-like flippers that make for smooth swimming. Much like other sea turtles, it will travel lengthy distances to find sites to feed as well as to lay eggs.

The Green Sea Turtle has a carapace length between 36”-48” (91-122 cm), carapace width of 27.5”-36.2” (70-92 cm), body height of 14.2”-18.9” (36-48 cm), and weight in the range of 243-419 lb (110-190 kg). The typical lifespan of the Green Sea Turtle is between 60-75 years in the wild and 80-120 years in captivity.

Sumatran Rhinoceros (Dicerorhinus sumatrensis)
Scale illustration of an average Sumatran Rhinoceros compared to other species of Rhino

The smallest rhinoceros in the Rhinocerotidae family is the Sumatran Rhinoceros (Dicerorhinus sumatrensis) found mostly in the Indian subcontinent and southwest China. It is also called the Asian two-horned rhinoceros or hairy rhinoceros, preferring rainforests, cloud forests, and swamps. It has two horns in the snout but is much smaller than those on the African continent. The hide is dark red-brown. There are also patches of a clump of hair along the ears, and the end of the tail. You may also find folds of skin around the neck, before the hind legs, and behind the front legs. It is agile, and an expert climber of steep slopes and riverbanks. The Sumatran rhinoceros is solitary and considered the most vocal among all rhinoceros.

Sumatran Rhinoceros' have a total body length between 7.9’-9.8’ (2.4-3 m), standing shoulder height of 4.4’-5.4’ (1.35-1.65 m), body width of 2.5’-3.1’ (.75-.95 m), and typical weight in the range of 1,102-2,094 lb (500-950 kg). The front horn of the Sumatran Rhinoceros has a length between 9.8”-31.5” (25-80 cm) while the rear horn has a length of 2”-3” (5-7.6 cm). Sumatran Rhinoceros' have lifespans between 30-35 years.
