Did you know that some animals have eyes that are so small they’re barely visible? From tiny rodents to elusive sea creatures, the animal kingdom is full of fascinating animals with small eyes. If you’re curious to learn more about these unique animals and their adaptations, you’ve come to the right place.
In this article, we’ll explore some of the most intriguing animals with small eyes and explore the reasons behind their unique features. So, let’s dive in and discover the fantastic world of animals with small eyes!
Wild Boar
Wild boars have a typical domestic pig shape with a long, blunt snout and a small head. Their eyes are small relative to their head; they have coarse hair.
Wild boars are omnivorous and feed on various food, including roots, tubers, fruits, and small animals. They are known to be very adaptable and can survive in a wide range of habitats, from forests to grasslands.
Wild boars are known for their aggressive behaviour, especially when they feel threatened or when they have young piglets. They have sharp tusks that they use to defend themselves.
Panda
Pandas have small eyes with large round black spots surrounding each eye, making them look even smaller. Pandas have a nearsighted vision and are thought to have limited colour vision. They make up for it with their excellent sense of smell.
Pandas are best known for their love of bamboo, which makes up almost all of their diet. They have a sixth digit, an enlarged wrist bone that helps them grasp bamboo stalks. Pandas also have a very slow metabolic rate, which means they do not need to eat as much as other animals of their size.
Scorpions
Scorpions are arachnids with small eyes and poor vision. They use their eyes to distinguish between light and dark and detect movement. Scorpions are predatory animals primarily consuming insects, spiders, and other scorpions. They are opportunistic predators that eat any small animal they can capture.
Scorpions have eight legs, and they are easily recognised by a pair of grasping pincers and a narrow, segmented tail, with its characteristic forward curve over the back. There are over 2,500 species of scorpions worldwide, with the majority living in deserts and other arid regions.
Despite their small eyes, scorpions have an impressive ability to detect prey and predators. They use their sense of touch, vibration, and smell to locate prey and avoid danger. Scorpions are nocturnal animals, and they are most active at night. They spend most of the day hiding in burrows or under rocks to avoid the hot sun.
Elephant
Despite their large bodies, elephant eyes are only about 1.5 inches in diameter. However, they have long eyelashes that help keep dirt and debris out of their eyes.
Elephants have poor eyesight and can only see up to 20 m. However, they make up for this with their excellent sense of smell and hearing. Elephants primarily orient themselves with their trunks rather than their eyes.
Despite their limited vision, elephants are emotionally intelligent animals. They can detect and respond to the feelings and emotions of others, making them empathetic creatures. Elephants live in herds and have strong social bonds, which is likely due to their ability to understand and communicate with each other through a variety of methods.
Pygmy Marmoset
The pygmy marmoset is the smallest monkey in the world, weighing just over 100 grams. Naturally, they have small eyes, about one-third the size of a human eye.
Thanks to their long, slender fingers and toes, they are highly agile and can move quickly through the trees. They can also turn their heads almost 180 degrees, allowing them to spot predators and other potential threats.
Pygmy marmosets are primarily arboreal, meaning they spend most of their time in the trees. They are active during the day and spend their time foraging for food, which includes insects, fruit, and nectar. They are also social animals and live in family groups consisting of a breeding pair and their offspring.
Poison Dart Frogs
These brightly coloured amphibians are known for their toxic skin secretions, which indigenous people in South America use to poison the tips of blowdarts. Their skin secretions contain a variety of toxins, including alkaloids, which can cause paralysis or death in predators.
They are small, the biggest measuring no more than 1.5 inches. There are 200 species of poison dart frogs, most of which are brightly coloured and patterned. They have small, beady eyes on the sides of their head.
Humpback Whale
When you think of whales, you might imagine them with big, expressive eyes. However, humpback whales have relatively small eyes compared to their massive bodies. The eye of a humpback whale is about the same size as a cow’s eye.
They are located on the sides of the whale’s head and allow them to see objects in their peripheral vision. This is useful for spotting predators or prey while swimming through the ocean.
Their best sense is hearing. They use echolocation to locate food and communicate with other whales. They also have a streamlined body shape, and powerful tail flukes that allow them to swim quickly and efficiently through the water.
Whale Shark
The whale shark is a gentle giant of the sea and is known for its large size. However, it also has relatively small eyes compared to its body. The whale shark’s eyes are located on the sides of its head, giving it a wide field of vision. This allows it to see predators and prey from a distance.
Despite their small size, the whale shark’s eyes are still functional. They can distinguish colours and shapes, which helps the shark find food. Whale sharks have a unique spiracle behind their eyes, which is an evolutionary remnant of their common ancestry with bottom-dwelling carpet sharks. This spiracle helps the shark breathe while feeding near the water’s surface.
The whale shark’s eyesight is not its primary sense. Instead, it relies on its sense of smell to locate food. The shark can detect the scent of prey from up to one kilometre away.
Eurasian Water Shrew
The Eurasian water shrew is a small mammal known for their long, pointed snouts, small eyes, and ears. Eurasian water shrews are found in wetland habitats such as rivers, streams, and ponds. They are excellent swimmers and can dive for up to 30 seconds. Their dense, velvety fur is waterproof, which helps them to stay warm and dry while swimming.
Eurasian water shrews are carnivores and feed on a variety of aquatic animals such as crayfish, water snails, small fish, and insect larvae. They have a high metabolic rate and must eat frequently to maintain their energy levels. Eurasian water shrews are one of the few venomous mammals in the world. They produce a toxic saliva that paralyses their prey and helps them to subdue larger animals.
Caterpillars
Caterpillars have small, light-sensitive eyes called stemmata. They have six tiny eyelets arranged in a semi-circle on each side of their head. One of the six eyelets is usually offset and located closer to the antennae. An insect with 12 eyes would have excellent eyesight, but that’s not the case. Despite having a large number of eyes, caterpillars have poor vision.
Caterpillars use their antennae to detect food and use their eyes to detect light. They can tell the difference between light and dark but cannot see colours. Some caterpillars have false eyes on their heads to deter predators. These false eyes look like natural eyes and make the caterpillar appear larger and more intimidating.
Caterpillars come in many shapes, sizes, and colours. Some caterpillars are hairy, while others are smooth. Some caterpillars are brightly coloured, while others blend in with their surroundings.
