Unique Island Animals

The world is an incredibly diverse place. There are billions of unique lifeforms within millions of different types of species and subspecies. And life exists in almost every type of terrain and climate on earth!

Certain species that live on islands have adapted in different ways from similar creatures on the continents. Due to their isolation, some of them have developed cool and unique features that aren’t found in their continental cousins.

One of the most unique places in the world for animals that you won’t find anywhere else is the Galapagos Islands of Ecuador. Located way out in the Pacific Ocean off the coast of South America, these groups of islands have some amazing creatures. Several of them make our list below, as well as a few others from other islands around the world. Let’s dive in and learn about these cool, unique island animals!

Marine Iguana

This iguana has a face that only a mother could love. While they generally look like other iguanas around the world, they have smashed in noses, eyes set wide apart, and what look like colorful, salt-encrusted heads! The famous scientist Charles Darwin, who spent many years in the Galapagos, described them as “hideous looking” and “the most disgusting, clumsy lizards.” That’s not very nice, Mr. Darwin!
Also known as the Sea Iguana, these fierce looking lizards are actually gentle herbivores. They’ve developed unique features on their bodies that make it easier to live on an island in the middle of the ocean.

For example, their tails are flattened laterally, similar to a crocodile, which allows them to be great swimmers. They also have long, sharp claws that allow them to cling to rocks underwater when there are heavy currents.

So, what do they like to eat? Almost exclusively seaweed and algae. Their short, blunt snouts and razor-sharp teeth make it easy for them to scrape these tasty treats off rocks. They’ve even developed an extra gland that helps to clean their blood of all of that salt they ingest while eating. Pretty neat!

Blue-Footed Booby

This funny-looking bird has a funny name to match, doesn’t it? While these birds can be found along the coasts of North and South America, the majority of them return to the Galapagos Islands during mating season to hatch their babies.

Their famous blue feet belong to the males, and they use them in an elaborate mating dance to attract a mate. (Maybe they were the inspiration for Elvis Presley’s song, Blue Suede Shoes?) Once they have chosen a partner, the egg is not laid in a nest but rather on the open ground, where the parents alternate sitting on it until it’s ready to hatch.

The Blue-Footed Booby is a great fisherman. They normally fish in flocks, and it’s quite the site to see a big flock of these birds circling in the sky before they dive into the water! An added benefit of their big blue feet is that once they dive in, they can swim for some time underwater as they go after their prey.

Giant Tortoise

The Giant Tortoise is probably the most famous turtle in the world. While they can be found on several different islands, the ones that most people know are from the Galapagos. They’re known not only for their giant size but also for their very long lifespan, with an average life of 100 years!
The oldest recorded Giant Tortoise was Tui Malila, a Madagascar Radiated Tortoise, who is said to have been 165 years old when she passed away in 1965.

Giant Tortoises are herbivorous and love to eat things like grass, cactus leaves, and fruits native to the Galapagos. There are two types of tortoises on the islands – one has a saddle-backed shell while the other has more of a dome-shaped shell.

Unfortunately, there aren’t many Giant Tortoises around anymore. They were hunted for food and trophies for most of the last two centuries, and only about 60,000 survive in the wild today. Lonesome George (pictured), for example, was the last of his particular species of Giant Tortoise to live. Thankfully, they are a protected species, and scientists and conservationists are optimistic that most species of Giant Tortoise can make a comeback.

Sally Lightfoot Crabs

These colorful little guys are known as the garbagemen of the Galapagos beaches – they’re responsible for eating anything and everything that washes up on shore! This is an important part of the island ecosystem to keep things clean and fresh. They even pick ticks off marine iguanas!
The rumor is that they got their name from a famous Caribbean dancer because they are extremely quick and agile. They can jump from rock to rock with ease and even are able to climb vertically!

The females carry their eggs on their stomachs, and when she’s ready to lay them, she swims into the ocean and lets them go in the water. The baby crabs spend their first couple of days eating phytoplankton until they transform into juvenile crabs and swim back to shore.

Bonin Flying Fox

This animal is not what you might think it is – it’s not a fox, but a bat! These furry flyers live on the Ogasawara Islands of Japan.

They are different than other types of bats because, instead of relying on echolocation to fly around at night and find food, they tend to feel their way around trees, moving slowly from branch to branch. Because of this, they mostly eat plants and fruits (a.k.a. herbivorous).

They also prefer to be by themselves instead of in great big bat colonies, though that changes when winter comes. Then they don’t mind being so close together and make a huge ball of bats to stay warm!

Pebble Toad

This toad is tiny and super cute! Barely over an inch long, the pebble toad is true to its name because it is dark and brown, and when it wants to get away from danger, it folds its arms and legs around its body and turns into a rolling pebble!

Not only is turning into something that can roll away useful to get away from predators like tarantulas and snakes, but it also allows them to hide in plain sight. Because of their color and shape, they also look like tiny rocks and therefore are able to camouflage right into their surroundings. This is good news for the pebble toad because it can’t move fast or jump far with its legs.

You can find the pebble toad on the islands just off the coast of Venezuela in South America.

Pygmy Three-Toed Sloth

This slow and sluggish animal was only recently classified as its own species of sloth, getting the distinction in 2001. It’s only found on Isla Escudo de Veraguas, a small island off the northern coast of Panama in Central America, and it’s considered a critically endangered species due to the destruction of its natural habitat and hunting by humans.

Also known as the monk sloth or dwarf sloth, it is significantly smaller than other types of sloths. A normal-sized male is about 20 inches long and weighs less than 8 pounds – that’s about the size of a small cat!
