Animals come in all different shapes and sizes, some have tails, and others have no tails. Some animals have very long tails, whereas others have very short tails. Today, I will cover 10 animals with the longest tails.
The 10 animals with the longest tails of all are:
- long-tailed grass lizard
- whiptail stingray
- giraffe
- spider monkey
- jerboa
- ring-tailed lemur
- common thresher shark
- green basilisk
- long-tailed widow bird
- whiptail stingrays have the longest tail, 14 feet (4.3 meters)!
Some animals have a very long tail but only relative to the rest of their body. Each animal with a very long tail has one for a different reason. Below, I will provide details about each animal with the longest tail and what they use it for.
Here’s a table showing the animals with the longest tail and the ratio. I ordered them from the biggest difference between their tail length and body.
Animal | Length of Tail | Tail-to-Body Ratio |
---|---|---|
Long-Tailed Grass Lizard | 8.9 inches (22.5 cm) | 3:1 |
Jerboa | 5.9 to 6.4 inches (15 cm to 16.2 cm) | 2:1 |
Whiptail Stingray | 13 to 14 feet (4.0 to 4.3 meters) | 2:1 |
Green Basilisk | 2 (60 cm) | 2:1 |
Long-Tailed Widow Bird | 11.8 to 19.7 inches (30 to 50 cm) | 1.6:1 |
Spider Monkey | 34 inches (86.36 cm) | 1.6:1 |
Ring-Tailed Lemur | 22 to 25 inches (56 and 63 cm) | 1.4:1 |
Tufted Ground Squirrel | 1 foot (30 cm) | 1:1 |
Common Thresher Shark | 9 feet (3 meters) | 1:1 |
Giraffe | 3 feet (1 meter) | 1:2 |
It’s interesting to note that even the animals above that have a tail that is the same length as their body look like they have a REALLY long tail. Here’s a breakdown of these animals and what they use their long tail for.

#1: Common Thresher Shark
The common thresher shark is fairly small. Common thresher sharks grow to about 9 feet long. But, their tail is the same length as their entire body, so most of their length is taken up by their tail.
With a relatively small body, the thresher shark’s tail is only very long on the top fin. Their tail is a long thin triangle with a pointy tip, whereas the bottom fin of their tail is a standard length for sharks.

Tail-to-Body Ratio: A common thresher shark’s tail is the same length as its body and has a tail-to-body ratio of 1:1. Therefore, half the length of a thresher shark is in its tail.
What They Use Their Tail For
Thresher sharks use their very long tail for hunting. Sharks commonly feed on fish, which are often very difficult to catch, especially when they are in a big school making it difficult for a shark and other predator fish to decide which fish to go after.
A thresher shark swims up as fast as it can to where a group of fish is, then stops suddenly and whips its long tail over its head to stun and kill as many fish as possible. It then gobbles up any fish it managed to hit.
Here’s a video from the discovery channel that shows this unique hunting method:
#2: Green Basilisk
Green basilisks are beautiful-looking lizards that are common pets. They have been nicknamed the ‘Jesus Lizard’ because they can run across water, which is achieved by running very fast.
The male green basilisk has a fin on its back and a fin on the top of its tail, as well as interesting ornaments on its head. The females and young green basilisks look very plain and don’t have appendages on their backs, tail, or head.
Adult green basilisks can grow as long as 3 feet (90 cm), and their tail is 2 feet (60 cm).

Tail-to-Body Ratio: A green basilisk’s long thin tail is twice as long as its body. Therefore, a green basilisk’s tail-to-body ratio is 2:1.
What They Use Their Tail For
Green basilisks use their tail for balance when running and climbing trees. They are capable of running on their hind legs. When they do, the green basilisk uses its long tail to stabilize its body.
When they run across water their long tail is a counterbalance that takes most of their body weight off their legs. Therefore, their legs are very light and allow them to outrun gravity and drag their tail as they run on water.
Green basilisks eat both insects and fruits. They rely on the element of surprise to snap up insects that haven’t noticed them. They harvest berries and munch on other fruits that fall to the ground or climb trees to eat them.
#3: Giraffe
Giraffes are huge and very well-known animals and are some of the most popular animals in zoos. Giraffes have very long legs and also very long necks. Their tails are not that long compared to the rest of their body, but their tails are overall quite long.

Tail-to-Body Ratio: A fully grown Giraffe’s tail is 31 to 39 inches (80 cm to 1 m) in length, and its body is about 14.1 to 18.7 feet (4.3 to 5.7m). However, most of this is taken up by their very long neck. A giraffe’s body is 7.5 to 8.5 feet long (2.2 to 2.6 m). Therefore, their tail-to-body ratio is 1:2. Their tail is half the length of their body.
What They Use Their Tail For
Giraffes’ tails have a long black tuft of fur on their end that they use to swat insects off their body. It can reach most of its hind legs and halfway up its body.
Giraffes are commonly attacked by groups of lions. When a giraffe is defending itself from lions it will curl its tail up so that lions can’t grab onto it.
#4: Tufted Ground Squirrel
The tufted ground squirrel is found on the Indonesian island of Borneo. It is very elusive and is rarely seen in the wild. It primarily eats fruits, seeds, and insects. It has a very large and long bushy tail that is the same length as its body.
Here’s a short video of this elusive squirrel caught on a trail cam:
It looks similar to the common squirrel. However, it’s slightly larger and has unusual tufts of hair on its head.

Tail-to-Body Ratio: Adult tufted ground squirrels have a body that is 1 foot long (30 cm). But, their tail is as long as their body. Therefore, they have a tail-to-body ratio of 1 to 1.
What They Use Their Tail For
Scientists are a bit baffled as to why tufted ground squirrels have such a large tail. The possible reasons that have been put forward are as a display during courtship (mating), and to confuse predators.
Using it to confuse predators seems likely. The reason is that the tail is mostly fur, so when a predator tries to grab onto it, they can’t get a good grip.
#5: Ring-Tailed Lemur
The ring-tailed lemur is a monkey-like animal that is only found on the remote island of Madagascar off the East coast of Africa. They are famously portrayed in the movie Madagascar. They have very long bushy, and beautiful tails. Their tails have black and white stripes and are very flexible.

Tail-to-Body Ratio: An adult ring-tailed lemur’s head and body are about 15 to 18 inches (39 to 46 cm) long, and their tail is 22 to 25 inches (56 to 63 cm). Therefore, their tail is significantly longer than their body. Their tail-to-body ratio is 1.4 to 1.
What They Use Their Tail For
Ring-trailed lemurs use their tails for communication. Lemurs live in groups of 15 to 30. When they are traveling along the ground, they will lift their tails up high in the air so that they can see who’s where.
They have one other use for their tail which is only used by the males. Male lemurs will rub their scent on their tails using scent glands on their forearms. Then they will challenge other male lemurs to a fight by swishing their tail in another lemur’s face. It’s a way of showing dominance, but if another lemur wants to challenge the pecking order a fight can break out.
#6: Spider Monkey
Spider monkeys are about the size of a dog. They have very long limbs and very long and strong tails. Spider monkeys are very coordinated with their tail and can use them like an arm.
Spider monkeys primarily live in trees, where they hang from their tail. They look like spiders that are hanging on by a strand of silk. A spider monkey’s tail has a skin-like area on the underside of the very tip of its tail. When they grab onto branches, their tail wraps around them a few times.
When baby spider monkeys are about 2 weeks old they will ride on the back of their mother. When they ride on their mother, they wrap their tail around the base of the tail of their mother. That way, they will never fall off.

Tail-to-Body Ratio: A full-sized spider monkey’s body is about 21 inches (53.3 cm) long, and its tail grows up to 34 inches (86.36 cm). The tail is much longer than its body, and their tail to body ratio is 1.6:1
What They Use Their Tail For
Spider monkeys live 114 feet to 164 feet (35 to 50 meters) above the ground. They also have pretty large and heavy bodies. The primary use of their tail is for grabbing and balancing. It offers an extra layer of security in case a tree branch breaks.
#7: Jerboa
Jerboas are fascinating small animals that look similar to a mouse. However, they are much larger than the size of a rat. They also have very long and thin hind legs that are almost identical to a kangaroo. When they walk, they also hop with both feet like a kangaroo but will also run alternating their feet.
Jerboas have a rat-like tail with a tuft of fur on the end that is very long relative to their body. They primarily live in deserts. During the day, they sleep in burrows.

They make their burrows in the sand where they can keep cool from the scorching temperatures during the day. They go foraging and hunting at night when temperatures are cooler. They eat seeds, insects, and plant pods.
There are many different types of Jerboa, such as the Egyptian jerboa and the long-eared jerboa.
Tail-to-Body Ratio: There are many different species of Jerboa, so I’ve chosen the long-eared jerboa to measure the body-to-tail ratio. A jerboa’s body is 2.8 inches to 3.5 inches (7 cm to 9 cm). Whereas their tail is double the length of their body, 5.9 inches to 6.4 inches (15cm to 16.2cm). Therefore, the tail-to-body ratio of a jerboa is 2 to 1.
What They Use Their Tail For
Jerboas primarily use their tail for balance. When jerboas are standing still, their tail is bent and the end sits on the ground. It acts like a minor 5th leg, helping a jerboa to balance. As a jerboa is running and jumping, its tail moves and flicks around behind them very fast.
It does this in response to minor variations in the terrain as they jump to allow them to stay balanced in the air, and land in an optimal way to jump again.
#8: Whip-Tailed Stingray
Whiptail stingrays are a type of stingray. All stingrays have a large, rounded, and flat body, and a whiptail stingray is no different. Whiptail stingrays have longer tails than other stingrays, and their tail is capable of delivering a painful sting.
Stingrays have mighty jaws that can crack open oysters and other shellfish. They also feed on crabs, other small animals, and sometimes fish.

Tail-to-Body Ratio: A whiptail stingray’s body is 6 to 7 feet wide (1.8 m to 2.1m), and its tail can grow as long as 13 to 14 feet (4.0 to 4.3 meters). This means their tail is about twice the length of their body. So, their tail-to-body ratio is 2 to 1.
What They Use Their Tail For
The primary purpose of a whiptail stingray’s tail is for defense against predators. Many stingrays don’t sting from their tail, but rather from a barb that is close to the base of their tail. However, many stingrays have spines along their tail. When they need to defend themselves, their tail can whip about and strike a potential predator.
#9: Long-Tailed Grass Lizard
Long-tailed grass lizards are a common pet. They have the longest tail-to-body ratio. In appearance, they look like other lizards apart from their incredibly long tail. They are reasonably small lizards.

Tail-to-Body Ratio: Their body is only 3 inches long (7.5 cm), while their tail is 8.9 inches (22.5 cm). Their tail-to-body ratio is 3 to 1.
What They Use Their Tail For
A long-tailed grass lizard uses its tail for defense. If a predator gets close enough to eat them, they will drop their tail and regrow it. A predator will eat their tail which is a more leisurely meal, and the long-tailed grass lizard can get away.
#10: Long-Tailed Widow Bird
The long-tailed widow bird is a small to medium-sized bird that is black all over, except for two red and white patches, one on each shoulder. It has unusually long tail features. In total, they have about 6 to 8 large and long tail feathers. They are native to a few African countries such as South Africa, Zambia, and Kenya.

Tail-to-Body Ratio: Male and female long-tailed widow birds are very different. Females don’t have the very long tail that the males have. Therefore, I will use male long-tailed widow birds for the tail-to-body ratio. The body of a male long-tailed widow bird is 7.5 inches to 8.3 inches (19 to 21 cm). Whereas, their tale is 11.8 to 19.7 inches (30 to 50 cm). So, their tail-to-body ratio is about 1.6 to 1.
What They Use Their Tail For
A long-tailed widow bird’s tail is primarily used for ornamentation and as a way of showing that a male long-tailed widow bird is a good mate for female long-tailed widow birds. Female long-tailed widow birds, by comparison, are yellowy-brown in color, much smaller, plain looking, and don’t have a long tail.
