List of 25 Animals with Big Eyes in the World (Largest Eyes 2024): Updated

Vision is one of the most important senses for the survival of an animal. Vision is usually achieved through a complex organ we call the eyes. The eye of every species differs in several aspects like shape, color, structure, and size. In the diverse animal world, a significant question arises, which animals have the Big Eyes? Therefore, we have come up with today’s article, list of 15 Animals with Big Eyes in the world.

The list not only focuses on animals that have the largest eyes but also on those which have large eyes in comparison to their body and head size and weight. Therefore, without much ado, let’s get going with our today’s article.

20 Animals with Big Eyes in the World

1) Colossal Squid

Colossal Squid has the largest eyes on the planet. They are one of the largest animals on the planet. With an enormous body, sometimes measuring nearly 40 meters long, they are also equipped with the largest eyes in the world.

Measuring up to 25 cm or 11 inches, their eyes are best suited for deep sea vision, where there are no traces of sunlight. Their large eyes help them to use the tiniest of light available emitted by certain crustaceans like jellyfish and use it to spot their predators, majorly the sperm whale.

  • Genus- Mesonychoteuthis
  • Scientific name- Mesonychoteuthis hamiltoni
  • Location- Worldwide distribution

2) Slow Loris

The first noticeable thing when one encounters these small endangered animals is their large rounded front-facing eyes. Slow Loris is a nocturnal hunter, and this is where their big eyes come into play.

They capture the maximum of the light available and help the animal to detect its next prey. Their eyes occupy a large portion of their head and are quite distinct in comparison to their small size.

  • Genus- Nycticebus
  • Scientific name- Nycticebus sp.
  • Location- South ane Southeast Asia

3) Ostrich


With eyes having a diameter of nearly 2 inches and occupying most of its head, the Ostrich holds the crown for the largest eyes of any terrestrial animal.

Their large eyes help them to spot predators from great distances, even up to 3-4 km away. Though beautified with large eyelashes, the eyes of an ostrich are so big that it leaves very little room for the brain.

  • Genus- Struthionidae
  • Scientific name- Struthionidae camelus
  • Location- Africa

4) Owl


Owls are undoubtedly one of the finest nocturnal hunters. Their large forward-facing eyes give them a wide field of binocular or stereoscopic vision. The pupils are large enough to allow even the faintest of lights, thus providing them with excellent night vision.

They have rod cells in abundance, which are responsible for their night vision. Owls have eyes that account for nearly 3% of their entire body weight. They can turn their heads 180 degrees, thereby achieving a 360-degree vision.

  • Genus- Strigidae
  • Scientific name- Strigidae sp.
  • Location- Worldwide

5) Blue Whale

Blue Whale

You might question our placing of Blue Whale on our list of Animals with Big Eyes, as they have relatively smaller eyes. But being the largest existing animal, the eyes of a Blue Whale are relatively much smaller.

Their eyeballs have a diameter of nearly 3 inches, which is quite large in itself. Blue Whales use their eyes to look for prey in the deep dark ocean waters or some rare cases, to swim away from predators.

  • Genus- Balaenoptera
  • Scientific name- Balaenoptera musculus
  • Location- Throughout the earth’s oceans

6) Swordfish


With eyeballs measuring up to 4 inches, the Swordfish is one of the animals with big eyes in the ocean. Swordfish’s eyes are greatly modified for vision in the deep-blue, cold ocean waters.

Their modified eye muscles can generate heat, which makes the blood going to the eyes warm, enabling the eye to catch the motion of fast-moving prey. Their visual response is so high that they can track extremely fast preys with ease, even the dim underwater.

  • Genus- Xiphias
  • Scientific name- Xiphias gladius
  • Location-Teopical and temperate parta of Atlantic, Pacific, and Indian Ocean

7) Horse


Next up, we have another terrestrial animal whose eyes rank up to one of the largest on the planet. Horses have eyes measuring nearly 2-3 inches in diameter, making them one of the largest of all mammals.

  • Genus- Equus
  • Scientific name- Equus ferus
  • Location- Worldwide distribution

8) Marmosets


The Marmoset’s eyes may not be the largest among the diverse catalog of animals, but they are relatively larger in comparison to their body size and weight.

With a diameter of nearly 11 cm, their eyes are larger than many primates in comparison to the size of their brains. Marmosets are getting increasingly popular for their ability to make highly interactive exotic pets.

  • Genus- Callithrix, Mico
  • Scientific name- Callithrix sp., Mico sp.
  • Location- South America, Central America ans Mexico

9) Tarsier


Tarsier may be one of the smallest primates on the planet, but their relatively large eyes are worth mentioning. Their eyes may be small but have a diameter of nearly 1.6-1.7 cm, which is larger than their brain.

They are nocturnal carnivorous creatures, mainly feeding on insects, and this is where their large eyes come into play. They amplify the slightest of light, aiding them greatly in their night vision.

  • Genus- Carlito
  • Scientific name- Carlito sp.
  • Location- emdemic to Phillipines

10) Chameleon


The chameleon is one of the most visually dependent predators. These slow-moving lizards have large bulging eyes, which are capable of independent 360-degree rotation.

They look like turrets that can rotate 90 degrees vertically and 180 degrees horizontally, giving them a wide panoramic vision, which can change to monocular or binocular.

Their eye slit might be small, but it’s the overall visual organ that gives them a place on this list of animals with big eyes.

  • Genus- Chamaeleoninae
  • Scientific name- Chamaeleoninae sp.
  • Location- In almost all forests of the world

11) Lemurs


Lemurs are nocturnal beings, which accounts for their large eye concerning their skulls. Their large front-facing eyes give them wide binocular or stereoscopic vision. Lemurs have tiny snouts and small bodies, which make their eyes appear even larger.

Their eye color is bright yellow or blue-eyes for some Scientific name name name name, and they lack a fovea, which distinguishes them from other creatures. These are dichromatic beings and are blind to long-wavelength colors like red.

  • Superfamily- Lemuroidea
  • Location- Endemic to the island of Madagascar

12) Tree frogs

Tree frogs

Certain tree Frog, especially the Red-eyed Tree Frogs, have bright red bulging eyes, which appear quite large, keeping in view their tiny body size.

These bright-colored bulging eyes help the frog in many ways than simple vision. They startle the predators for a few seconds, giving the frog enough time to escape. These are nocturnal beings and are therefore highly dependent on their eyes for survival.

It is the smallest fox species and has adapted to high temperatures and little water. It has a lifespan of up to 14 years in captivity and about 10 years in the wild. The fennec fox has sand-colored fur, a black nose, and a tapering tail with a black tip. Its ear to body ratio is the greatest in the canid family, likely aiding in heat dissipation and locating vertebrates.

  • Genus: Vulpes
  • Scientific name: Vulpes zerda

24. Sugar glider

The sugar glider is a small, omnivorous, arboreal, and nocturnal gliding possum, known for its predilection for sugary foods and ability to glide through the air. Its scientific name is Petaurus breviceps. The sugar glider has a squirrel-like body with a long, partially prehensile tail, and is a sexually dimorphic species, with males typically larger than females.

The fur coat is thick, soft, and usually blue-grey, with a black stripe from its nose to midway on its back. Males have four scent glands, while females have a paracloacal scent gland and a scent gland in the pouch. The sugar glider is nocturnal, with large eyes for night vision and swivel ears for prey identification. Each foot has five digits, with opposable toes on each hind foot for firmly grasping branches. The gliding membrane extends from the outside of each forefoot to the first digit of each hind foot, supported by well-developed muscles.
