1. Ibex

The Ibex is a familiar sight in the highlands of Europe, Asia, the Middle East, and northern Africa. It is one of the primary ancestors of the domestic goat.

There are five primary species, although according to some research if you count subspecies, there may be as many as eight. Wild goats known as ibex have long horns that bend over their backs and cloven-hooved feet. Males generally grow beards as well.

The animal can scale precipitous cliffs because of the way its hooves function as suction cups. Within the genus, the Siberian ibex has the largest horns, measuring 100–148 cm. Most males and females spend the majority of their lives in herds that are divided by gender. Ibex herds avoid “escape terrain” in the form of high cliffs.

These animals usually congregate in herds according to gender. It follows that there are separate male and female herds. Bachelor herds are a common name for male herds. A breeding season is the only time the two herds come together.

There are occasions when older males will stray off by themselves. Typically, female herds contain 10 to 20 animals. Normally, the animal would run away from people, but during rutting season, males may become especially hostile and charge.

Today, there are believed to be around 30,000 alpine ibex in the wild, making them extremely common. However, it is estimated that there are just 500 members of the Walia species left, making them an endangered species.

It is estimated that there are 9,000 Iberian ibex in the wild. According to the IUCN, the Nubian species has about 10,000 mature animals left and its population is shrinking, placing it in a vulnerable category.

2. IMG Boa

The IMG boa constrictor’s color varies with maturity, frequently turning nearly black.

Ball pythons have been drawn to designer snakes for several years. Boa constrictors, on the other hand, are less prone to color and pattern mutations, therefore, breeders are continually working to create new, stunning colors for snake fans.

Age-related melanism is referred to as having an “Increased Melanism Gene” (IMG). Boa constrictors can grow up to 13 feet in length, depending on the environment and feeding schedule. As they age, IMG boa constrictors occasionally get practically black.

Boa constrictors are at home in a variety of South American natural settings. Except for Chile and Uruguay, their range encompasses the majority of the continent, including Brazil, Bolivia, and Venezuela.

Boas can be found in rocky terrain, arid grasslands, tropical rainforests, and the Amazon Basin. These snakes appear to have developed a breeding population in southern Florida, which is harming local fauna in numerous ways.

They can consume larger warm-blooded prey, such as small deer and even native alligators., because of their huge size. In Florida, boa constrictors and Burmese pythons are hunted by wildlife management professionals and snake hunters to control their numbers.

Setting up a suitable cage for your boa would be made easier if you keep in mind the native habitats. These semi-arboreal snakes require a lot of space for climbing and on the ground. Due to their stature, adults of the species spend more time on the ground than in the trees.

However, giving them access to climbing keeps their minds engaged. These are rather active snakes, and even handling one requires more effort than handling a ball python does since boa constrictors are so curious.

IMG boa constrictors consume small mammals, birds, snakes, and lizards, just like other boas do. They are opportunistic and will consume nearly any type of prey that will fit in their mouths.

3. Imperial Moth

The royal moth doesn’t consume food, thus it does pass away soon after laying its eggs. It just has a week or so to live. The moth that resembles a dead leaf, please!

One of the most common, substantial, and attractive silkworm moths is the imperial moth. Its wingspan can be over 6 inches, and its color resembles an autumn leaf, which likely shields it from predators during the day.

This beautiful moth has a fleeting lifespan because it only exists to procreate. Even the harmless but enormous, voracious, and terrifying larvae of this moth are fascinating.

Imperial moths don’t eat. Their mouthparts are immature, and they expel their digestive systems as they emerge from the pupa or eclose. The larvae or caterpillars of imperial moths have five instars.

This means that each instar is bigger than the previous one and that they molt four times before they are ready to pupate. Even the first instar differs visually from the previous one. Instead of spinning cocoons, the caterpillars burrow into the ground to pupate.

For silkworm moths, which are known to construct cocoons comprised of glossy silk, this is rare. The claws on the rear of the imperial moth pupa help them pull themselves out of the ground.

4. Indian Giant Squirrel

A sizable rodent species that are indigenous to India is the Indian giant squirrel. It is a special variety of tree squirrels. Due to its striking colors and distinctive size, this animal differs in appearance from the majority of other squirrel species.

The Malabar gigantic squirrel is another name for the Indian giant squirrel. One of the world’s largest squirrels is this extraordinary creature. An Indian gigantic squirrel’s tail generally exceeds the size of its body.

The 20-foot range that the Indian giant squirrel can cover is amazing. Due to their distinctive color, Malabar gigantic squirrels are sometimes known as “rainbow squirrels.” The state animal of Maharashtra, India, is the Indian giant squirrel. Being arboreal, Malabar giant squirrels spend most of their time in trees.

These enormous squirrels can be recognized for their vibrant colors. The hues differ from squirrel to squirrel. A typical pattern consists of two to three colors, such as white or cream, brown, black, red, maroon, and occasionally dark Fuschia.

The lighter hues are found on the underside and the long, bushy tail, while the deep colors are most prominent along the body. They can firmly grab trees because of their powerful claws. This species’ males and females look remarkably similar to one another.

To set them apart from one another, they have a few distinct qualities. Females typically measure approximately three centimeters larger than males and have mammae for nursing their young.

In their natural environment, Indian gigantic squirrels utilize their colors as camouflage and their tail as a counterbalance to help them balance on tree limbs. To avoid predators, they will also stay motionless and seem flat when attacked, blending in with tree bark.

5. Indochinese Tigers

Southeast Asia is the home of Indochina tigers. They have an orange or gold coat with a black striped pattern on it. This tiger is solitary and spends most of its time in hiding. In the wild, they can live for 15 to 26 years.

Tigers from Indochina are carnivores. They hunt at night since they are nocturnal. These tigers can be found in grasslands, mountains, and tropical rainforests. On the list of threatened species is the Indochinese tiger. The maximum weight of a male Indochinese tiger is 430 pounds!

These tigers have black and orange or yellow coats. When they are seeking food in the jungle, their fur color helps to keep them hidden. Tigers are difficult to spot because their stripes mix in with the rainforest’s shadows.

The stomach, face, and neck of this tiger are all covered with white fur. These large cats hunt at night and have bright yellow or light-colored eyes that enable superb night vision.

Additionally, they have keen hearing, which aids in the detection of prey like deer, wild boar, and even monkeys.

These tigers have long, retractable claws. This implies that the tiger can retract its claws into its paws when not in use. These claws enable tigers to safely climb trees by holding onto the bark.

This tiger can leap onto tall tree branches, swim, and chase prey with ease thanks to its powerful back legs. This tiger is capable of running at speeds of up to 60 mph. Therefore, this tiger moves almost as quickly as a pitcher throwing a curveball.

These tigers live in solitude. Only when mothers are caring for pups and during the mating season will you see several of these tigers together.

These tigers are shy and prefer to remain unseen. But if another male tiger enters its territory, a male will become hostile, especially during mating season.

Have you ever witnessed a cat in your area rubbing against a tree’s bark? One method used by cats, including these tigers, to mark their territory and warn other cats to keep away from it is by doing this.

The Indochinese tiger is classified as endangered for conservation purposes. Due to poaching and habitat destruction, the population is declining.

Because Indochinese tigers are so adept at hiding, it is challenging to assess their overall population. However, it’s estimated that only 350 of them are still alive. Thailand is home to the majority of Indochinese tigers.

6. Indigo Snake

The long, black, non-venomous indigo snake, sometimes known as the eastern indigo snake, is a native of the southern and central United States. With its enormous size, iridescent blue-black scales, and brave hunting, this magnificent snake is stunning.

It is the longest native snake in the United States. Venomous snakes will be attacked and eaten by an indigo snake. It defends itself by exuding a repulsive odor. When backed into a corner or startled, it shakes its tail. An indigo snake often establishes a three-mile hunting radius. The favorite waterholes and burrows of the snake are located in this area.

During the coldest period of the winter, indigo snakes brumate. They look for other species’ burrows, particularly those of gopher tortoises, which are hiding places when the nighttime lows fall below the fifties.

They frequently use the same burrow each winter, therefore the disappearance of gopher burrows had a significant influence on their ability to survive. Indigo snakes spend the winter in the burrows of rodents, armadillos, or land crabs in places without gopher tortoises.

An annual clutch of 6 to 12 eggs is laid by the female indigo, which mates from October to February. At birth, baby indigo snakes range in length from 16 to 24 inches. Eastern indigo snakes are not dangerous to people.

The main factor contributing to the population reduction of snakes is humans. Indigo snakes have been unlawfully captured by humans for the pet trade, and as the snake’s habitat has developed, deaths from domestic animals, automobile accidents, and pesticides have occurred.

Eastern indigo snakes are categorized as threatened under U.S. law even though the International Union for the Conservation of Nature (IUCN) lists them as having “least concern.” They were added to the Endangered Species Act’s list of protected species in 1978.

It is prohibited to handle a snake without specific authorization and specialized training in the United States due to the snake’s legal protection.

7. Inland Taipan

One of the world’s most lethal venoms is said to be produced by the inland taipan.

The ferocious snake, small-scaled snake, or western taipan, sometimes known as the inland taipan, can easily kill a person with a single bite, although curiously, very few fatalities have ever been documented. Only when they feel directly threatened will they attack. However, this species must be completely avoided.

One of the most intriguing facts is that it is believed that male inland Taipans fight one another to win the attention of females. Their bodies entwine at this point, and with their lips shut, they lash out at one another.

It is believed that these snakes breed in the late winter. Each female will produce a clutch of between 11 and 20 eggs. They can lay two clutches each season in captivity. After hatching from the egg, the young taipans measure about 18 inches in length.

There are not many animal predators of the inland taipan. However, it is known that the king brown snake and the perentie monitor lizard also eat young taipans.

One specimen in the Australia Zoo lived to be over 20 years old when the average lifespan of an inland taipan is between 10 and 15 years. The inland taipan is surprisingly placid and reserved around people considering how deadly it is.

They can be handled by professionals without getting bitten frequently. This snake won’t normally bite people in the wild unless provoked, cornered, or handled improperly. It will pose a threat by bending its upper body upward before flashing a warning signal. Anyone who isn’t currently working with this snake should avoid it at all costs to avoid a bite for obvious reasons.

The inland taipan is a species of the least concern, as per the IUCN Red List. Despite having a rather restricted range in central Australia, there don’t seem to be any major threats to it there. With any degree of accuracy, population estimates have never been made.

8. Ivory-Billed Woodpecker

In the American South and Cuba, the ivory-billed woodpecker is one of the most elusive species of bird.

Since the last reported sighting in 1987, people have been searching the southern woodlands and marshes for indications of this famous animal, which is thought to be extinct. The ivory-billed woodpecker was regarded as a top ecosystem engineer when it was still widespread.

They were able to bore holes in trees with their long, pointed beaks, constructing houses not only for themselves but also for other species. When woodpeckers chisel into trees, they emit peculiar noises. Experts can even tell different species apart based on the noises they produce while they burrow.

To keep out detritus when it drills into the wood, this species has tufts of white feathers around its nose. Although the ivory-billed woodpecker is a sedentary bird that stays close to home, some researchers have hypothesized that it might occasionally roam around to take advantage of recently deceased trees.

A prominent crest on the back of the head, a long ivory-colored bill, and curled black claws are the distinguishing features of the ivory-billed woodpecker. The bird has white stripes going from the wings to the side of the head and is coated in glossy black plumage.

The white color of the innermost wing feathers is also noticeable when the wings are folded against the back. The largest woodpecker in the entire United States, this bird is between 19 and 21 inches long. Overall, guys tend to be a little bit bigger than girls. In addition, their crest is red rather than black.

The ivory-billed woodpecker appears to be completely reliant on forests for its entire existence. It spends all of its time in and near trees, foraging, roosting, and reproducing. The woodpecker exhibits little violence toward other members of its species, suggesting that each mated couple maintains its distinct home range and is not inherently defensive or territorial.

Although it isn’t gregarious in the traditional sense, it has been seen gathering in groups of three or four birds at once. The majority of the day is spent searching for food with the ivory-billed woodpecker. When they emerge from the hole in the morning to preen and call for mates, their activity peaks.

After a brief lull in the middle of the day, they resume their activity in the late afternoon. When night falls, they each roost in a different cavity. Since the ivory-billed woodpecker is not known to migrate, its range is likely limited to a few kilometers around its nest. How many of these woodpeckers are still living in the wild is unknown.

This species was thought to be functionally extinct in the wild and in captivity after decades of decline in the 19th and early 20th centuries, but there is still a chance that it will one day be rediscovered in the forested swamps of Cuba, Louisiana, Arkansas, or Florida. Its status was eventually upgraded to critically endangered based on unverified sightings.

Here is a short video on some of the animals that start with I. You may find out that we’ve just brushed the surface of these animals in our article, as there are more animals that start with I than those listed in this article.


Some of these creatures are uncommon and cannot be encountered frequently. Others are widespread and are visible all around you. But every one of them is fantastic and deserves to be on our list.
