With an average head length of 4’11 ft (150 cm) and a shoulder height of 2’11 ft (90 cm), these magnificent animals are built for the rugged terrain they inhabit. Female ibex weighs approximately 88 lb (40 kg), while males can tip the scales at over 220 lb (100 kg).

2) Iberian frog

The Iberian frog, known for its unique call, is a precious species that resides in Portugal and Spain. It’s a sad reality that their population is vulnerable due to several factors like deforestation, climate change, water pollution, and others that are taking a toll on their habitat. They deserve to thrive in their natural environment but are forced to adapt to changes that are beyond their control.

3) Ibis

The Ibis, a bird revered by the Ancient Egyptians, was highly respected for its unique characteristics. Known for its ability to feast on almost anything edible, the Ibis has a unique diet that includes insects, small fish, and even aquatic animals.

In their early days, these dogs were used for hunting rabbits, but they were also known to hunt for food in Egypt. Despite their hunting instincts, Ibizan Hounds make excellent family pets that are loyal and affectionate. However, if you have cats, it might not be a good idea to introduce them to each other, as these dogs have a strong instinct to chase smaller animals.

Fun fact: The first two Ibizan hounds brought to the United States were owned by Colonel and Mrs. Consuelo Seoane.

5. Icefish

The white-blooded fish, also known as Chionodraco hamatus, is certainly a unique and fascinating creature. These fish call the southern ocean home, specifically around the icy region of Antarctica. But what truly sets them apart is their white blood.

Their striking appearance is one reason why they’re so popular as pets. Iguanas come in a range of colors, from earthy browns to bright greens and yellows.

8. Immortal Jellyfish

The Benjamin Button Jellyfish, also known for its incredible ability to regenerate and live indefinitely, is truly one of the most fascinating aquatic creatures in the world. Not only are they some of the oldest living animals documented, but their unique name also adds to their allure. These jellyfish have the ability to reverse the typical aging process, making them seem as if they are growing younger as time goes on. But what’s even more extraordinary is their ability to hitchhike on cargo ships, traveling vast distances without much effort at all.

9. Impala

If you ever find yourself on a safari in Southern or Eastern Africa, keep an eye out for the graceful Impala. These beautiful animals are herbivores that have a discerning palate when it comes to their water source – they prefer clear lakes or rivers to murky ponds. During the rainy season, they gather in herds, adding to their already impressive spectacle. Fun fact about male impalas: their horns can grow as long as their body height, making for an intimidating sight.

10. Imperial Moth

Imperial moths are a sight to behold with their vibrant exoskeletons that come in a variety of colors. Their coloration is particularly interesting, as it mimics that of a dead leaf, providing a natural camouflage against predators. What’s even more fascinating is that despite their short lifespan of just one week, these insects never eat.

11. Indian Cobra

The world is home to a wide variety of snakes, but there is one in particular that stands out as one of the most dangerous. This particular snake, which can live for an astonishing 24 years, can grow to be between four and seven feet long. Though it is a protected species in India, it is often used by snake charmers due to its important place in Hindu mythology. Despite its potential danger, there is no denying the allure of this fascinating animal.

12. Indian Palm Squirrel

In India, there is a special type of rodent that is considered to be sacred. The Indian Palm Squirrel is a native of India and Sri Lanka and holds a special place in Indian culture. These squirrels are known for their small size, bushy tails, and adorable faces. While they are omnivores and can eat a variety of foods, they have a particular preference for nuts and grapes. What makes these squirrels even more unique is that they don’t hibernate like other squirrels do.

13. Indian Rhinoceros

The one-horned rhino, also known as the Indian rhinoceros, is a magnificent creature that was on the brink of extinction. These herbivores have unique leathery skin that comes in stunning shades of brown, grey, and black. This remarkable animal can weigh up to a whopping 3,000 kilograms, making them one of the heaviest land animals in the world! While the one-horned rhino is still under threat, their numbers have been steadily increasing over the past few years. It’s amazing to know that this once-endangered species has now moved from the “endangered” to the “vulnerable” category.

14. Indian Star Tortoise

The Indian Star Tortoise is a fascinating creature that has captured the attention of many in the exotic pet trade. This species of tortoise is known for its distinct star-patterned shell, which makes it easily recognizable. Although they are native to Sri Lanka, Pakistan, and India, their ability to adapt to different climates has allowed them to thrive in other parts of the world as well.

15. Indochinese Tiger

The Indochinese Tiger, a majestic mammal that roams the secluded mountain forests of Southeast Asia, is a sight to behold. Its strip pattern is unique, and no two tigers possess the same markings. Despite its solitary nature, this animal can reach remarkable speeds for its size and mass, making it a formidable predator during nocturnal hunts. Sadly, the Indochinese Tiger is now listed as an endangered species, with some reports suggesting its extinction in China.

16. Indri

The Indri is truly a unique animal. As the largest species of Lemur, they are an impressive sight to behold. With specialized toes and fingers, they have the ability to climb efficiently and effortlessly through trees. However, Indri’s beautiful home is under threat due to habitat loss. These amazing creatures are now classified as endangered, making them all the more precious. And if that weren’t enough, the Indri is also an exceptional leaper, able to jump up to 10 meters between vertical branches.

17. Irish Setter

The Irish Setter is a beloved breed found in Europe that is sure to steal your heart with its sweet and fun-loving nature. Known for their energetic personalities, these furry friends love to play and run around with their owners. Not only are they great companions, but they also have quite a long lifespan, living up to 16 years on average.

18. Irish Wolfhound

The Irish Wolfhound is a magnificent breed of dog. These furry friends are known for their impressive size, towering over most dogs. They are incredibly friendly with their owners and make great family pets. However, don’t let their docile nature fool you, these dogs have a fierce hunting instinct that they won’t hesitate to use when needed. In fact, back in the day, Irish clans used the breed as war dogs! It’s no wonder the breed got its name from their role in controlling the wolf population.

19. Italian Greyhound

The breed of dog that we’re talking about goes back centuries and has been around since the Roman empire. These dogs were especially popular among the wealthy during the Italian Renaissance. One of the things that makes them so unique is their coat – they come in a variety of colors including red, black, brown, and even yellow and blue. While they can be found all over Europe, they are especially popular in certain countries. And if you get one of these pups, you’ll be blessed with many years of loyal companionship as they can live up to 15 years.

20. Ivory-Billed Woodpecker

The Ivory-Billed Woodpecker was once a thriving species across the Southeast of the United States and Cuba. Unfortunately, their impressive ability to drill into wood with their beaks wasn’t enough to keep their population safe from deforestation. Hollow trees are crucial for these birds to build their nests and secure their survival. Sadly, this crucial part of their natural habitat has been disappearing at an alarming rate, putting their existence in jeopardy.
