Eastern Lowland Gorillas, also known as Grauer's Gorillas, live in the eastern Democratic Republic of the Congo home, specifically two national parks and surrounding forests. It thrives in the broadest range of altitudes, from lowland tropical forests to mountainous terrains.
They are also the largest gorilla subspecies, earning the rank of the heftiest living primate. Its appearance resembles a mountain gorilla with a jet-black coat, albeit shorter on the head and body.
Despite seasonal changes, Eastern Lowland Gorillas exhibit steady nesting patterns1. However, habitats differ between adults and young, with immatures favoring tree nests, indicating vulnerability. Moreover, the absence of an alpha silverback substantively influences nesting choice, signifying the male's critical protective role.
However, our knowledge of its social patterns, history, and ecological role is currently limited. This unfortunate situation stems largely from ongoing civil unrest in the Democratic Republic of the Congo, which hinders consistent research efforts. This circumstance underscores the cross-link between human-generated strife and our ability to study and protect crucial elements of biodiversity.

The Western Lowland Gorilla is the nominate subspecies of the Western Gorillas found in Cameroon and other parts of Central Africa. It is also the smallest of the four subspecies.
This type of gorilla has black skin and coarse black hair except for the bare face, ears, hands, and feet. Notably, Snowflake, the unique albino gorilla from Equatorial Guinea, hailed from this species. Taken as a youngster to the Barcelona Zoo in 1966, Snowflake's pale form intrigued the world.
Contrary to previous beliefs that gorillas were non-territorial, studies have shown that their neighbors' locations influence their movements. They demonstrate a preference against feeding in areas visited by another group the same day, indicating a more nuanced territorial behavior4.
Interestingly, Western Lowland Gorillas show signs of tool use. A recorded instance in 2009 reveals a gorilla using a stick to gauge water depth while another used a bucket to collect water at Buffalo Zoological Gardens. This display of spontaneous tool utilization for drinking, particularly among younger females, provides a unique glimpse into gorilla cognition.
Lastly, a serious concern with western lowland gorillas is their link to zoonotic diseases. Scientists believe them to be one of the sources of HIV/AIDS transmission. This is attributed to the Simian immunodeficiency virus (SIV) in gorillas, which surprisingly resembles a strain present in HIV-1.
Cross River Gorillas live in the border zone between Nigeria and Cameroon. The habitat is broadleaf forests with altitudes ranging from 328 feet to 6,683 feet.
In physical attributes, it bears shorter skulls, smaller cranial vaults, and smaller palates than the previous type of gorilla subspecies. However, size and limb length match closely. One distinctive aspect of Cross River gorillas is their shorter hands and larger opposability index.
In general, wild gorillas are not dangerous. However, they can show aggression when disturbed. Behavioral differences emerged in a three-year study at Kagwene Mountain, Cameroon. The Cross River gorillas threw fistfuls of grass3, branches, and stones. Researchers concluded this action is a learned response to local conditions.
The nesting habits of Cross River gorillas also differ by environmental conditions. During the dry period, most nests are found on the ground, but in the wet season, they opt for tree-high nests to shield them from the rain.
They also make more day nests during the rainy season and reuse old nesting sites around 35% of the time. These patterns highlight the adaptive and intelligent characteristics of this incredible gorilla subspecies.

The Mountain Gorilla endures high altitudes within the cloud forests of three national parks, spanning across the Virunga volcanic mountains and extending its reach into one of Uganda's national parks. This species inhabits zones climbing up to 7,200 to 14,100 feet.
Unlike other types of gorillas, the Mountain Gorilla possesses thicker, longer fur designed to withstand colder climates inherent in its environment.
Despite being smaller than the Eastern Lowland Gorilla, adult male gorillas demonstrate distinctive bony crests atop and at the back of their skulls, giving them a conical appearance. These crests also anchor their powerful jaw muscles.
Starting in 1967, Dian Fossey dedicated 18 years to a detailed study of mountain gorillas. She brought new findings to light, implemented accurate counts, and introduced helpful conservation methods, like anti-poaching patrols. Her work continues through the Dian Fossey Gorilla Fund International, protecting Virunga's mountain gorillas.
Similarities in genetic makeup to humans expose mountain gorillas to human diseases2. An immune system ill-developed against such diseases results in respiratory infections, accounting for approximately 20% of sudden deaths among these gorillas.
As per the latest International Union for Conservation of Nature (IUCN) assessments, Gorilla conservation status exposes some alarming trends. Three of four sub-species of gorillas have been declared critically endangered with declining gorilla populations.
In 2013, Western Lowland Gorillas numbered 361,919, which is currently shrinking by roughly 2.7% annually. By estimates, this downward trend could result in over an 80% population decline across just three generations.
Cross River gorillas, known to us since the early 20th century, only received notable attention in the late '80s. Now, merely 100-250 mature individuals remain in the wild.
Grauer's Gorillas, valued at just 3,800, have suffered a drastic 77% population decrease since 1994.
Mountain Gorillas are not entirely clear despite their reclassification from critically endangered to endangered species5. While recent counts estimate at least 1,004 individuals, legal and illegal human intrusion into their habitats could threaten them again.
Regardless of the varied threat levels, all gorilla subspecies face common dangers. A relentless onslaught of habitat destruction, hunting, and diseases such as the ebola virus poses significant risks. In response, conservation efforts have been deployed to counteract these threats.

Fun Fact: Did you know the Eastern Gorilla is the largest gorilla subspecies? These massive apes can reach up to 6 feet tall when standing upright. With their muscular build and powerful arms, they can weigh up to a whopping 400 pounds.
The Eastern Diamondback Rattlesnake is a large venomous snake native to the southeastern region of the United States.
It can grow up to 8 feet long and has a unique zigzagging diamond pattern in bright yellows and earth tones on its back. This colorful pattern warns other animals of its lethal venom. Its dark skin allows it to blend in with fallen leaves and shadows.
The Eastern Diamondback lives in various habitats, from North Carolina to Louisiana, from pine-clad flatwoods coastal scrub habitats to barrier islands.
Despite their menacing appearance, they are not typically aggressive. Besides its prey, the Eastern Diamondback only attacks other animals when the snake feels threatened. Its venom paralyzes its victims and aids in digestion.
Before biting, the snake will shake its rattle, made from the same keratin found in hair and nails, to warn intruders.

The Eastern Diamondback Rattlesnake is the largest species of rattlesnake in the Americas and the heaviest venomous snake.
It can grow to a maximum length of eight feet and has diamond-shaped dark brown, black, and yellow markings. Its head is triangular, with a dark stripe running through each eye.
They use their rattle at the end of their to hunt prey. Rattlesnakes of this kind are solitary creatures that seek out other rattlesnakes only during the breeding season.
The Eastern Gray Squirrels live in woodlands and urban areas throughout the eastern and midwestern US and eastern provinces of Canada2.
These agile creatures are most active during sunrise and sunset. Eastern Gray Squirrels also store food in secret stashes, which benefits them and the environment by spreading seeds far and wide.
One of their most impressive tricks is their unique agility. For instance, their ankles can rotate 180 degrees, allowing them to make a death-defying head-first descent down trees.
The eastern long-necked turtle is native to swamps, lakes, and inland waterways in Eastern Australia. It is a carnivorous aquatic animal that feeds on small fishes, tadpoles, and invertebrates.
The unusual animal has a long neck up to the length of its shell. It also has webbed feet for digging and swimming. The long-necked turtle releases acrid liquid from its armpit and groin whenever it feels threatened.
The Eastern Newt, living in eastern North America, inhabits small lakes, ponds, streams, and adjoining wet forests. It is also called the Red-spotted Newt.
It has a unique three-stage life cycle; it begins as aquatic larvae, transforms into land-dwelling juveniles known as 'efts,' and eventually returns to the water as mature adults. During the eft stage, their skin turns bright orange-red, which warns predators about the toxic chemicals in their skin.
The eastern newt secretes tetrodotoxin, providing a chemical defense against predatory fishes and invertebrates. However, bullfrogs are unaffected by the toxin and readily consume the creature. Therefore, newts still sustain high predation levels2 in fish-containing habitats due to bullfrogs.
The eastern box turtle is endemic to the Eastern part of the United States. Eastern box turtles are slow and terrestrial. The turtle’s shells are high and dome-shaped, with colors ranging from brown to black. There are yellow and orange lines or spots on their carapace. Furthermore, a male eastern box turtle has red irises, while females have brown irises.
These turtles can grow up to 8 inches long with horned beaks. They are omnivores, feeding on a variety of animals and plants. Their diet contains earthworms, slugs, snails, mushrooms, beetles, flowers, and grubs. They avoid stressful environmental conditions as they prefer moderately wet forest areas with good drainage.
A close relative of these guys, the ornate box turtle, is the other terrestrial turtle native to the US.
The eastern mud turtle, also known as the common mud turtle, is native to the United States. However, it can be tricky to identify these aquatic species because they do not have any markings or patterns on their shells, unlike the striped mud turtle also found in the US.
In addition, they only grow up to 4 inches in length. Eastern mud turtles have a yellowish-grey chin and throat, their limbs and tail are grey, and their eyes are yellow with dark clouds.
They also have webbed feet. They are omnivorous and feed on insects, crustaceans, mollusks, amphibians, and aquatic vegetation. They prefer to live in freshwater regions in the Southeastern and Northeastern United States.
Eastern cottonwood is another widely distributed tree in America. It is a large tree that grows along streams, rivers, and lowland areas. It is the oldest and largest hardwood tree in North America, reaching a height of 100 feet and width of 75 feet. The tree species got its name from its seeds, which resemble cotton.
Eastern white pine is a native species of North America. This Maine and Michigan state tree has gray-brown barks, broad ridges, and scaly plates. It can grow between 50 to 80 feet tall.
