Excavating tunnels that can span up to 100 feet in a day, moles are remarkable creatures with unique adaptations. Among the adaptations that enable them to spend most of their lives underground are their strong forelimbs and claws. But have you ever wondered how these forelimbs and claws work and what they allow moles to do underground? In this article, we will take a closer Insight into the anatomy of moles’ forelimbs and claws, their functions, and the challenges they pose.
Anatomy of Moles’ Forelimbs and Claws
When it comes to burrowing animals, moles are some of the most impressive. These small creatures have adapted to living underground in ways that are truly remarkable. One of the keys to their success is their strong forelimbs and claws, which help them to dig, move, and survive in their subterranean world. In this section, we will explore the anatomy of moles’ forelimbs and claws in more detail. We’ll look at their unique structure, consider why they are so robust, and compare them to other animals with similar adaptations. For more information on the physical characteristics of moles, check out our article on the topic.
Structure of Moles’ Forelimbs and Claws
Moles are fossorial mammals that are adapted to living underground. Their forelimbs and claws are uniquely designed for digging tunnels and moving around in soil. These adaptations include several distinct structural features, such as:
- Robustness: Moles’ forelimbs are muscular and sturdy, allowing them to move large amounts of soil.
- Flexibility: Moles’ forelimbs are also highly flexible, which helps them move around in tight spaces and turn corners in their tunnels.
- Length: The length of moles’ forelimbs is another key adaptation for life underground. The limbs are relatively long compared to the animal’s body size, which enables them to reach far into tunnels.
- Sharp claws: Moles’ claws are long and extremely sharp, making it easier for them to claw through soil and roots. They also help the animal anchor itself in the dirt while digging.
- Rotatable wrists: Moles’ wrists are specialized for rotating and moving dirt efficiently. This allows them to dig quickly and avoid dirt blockages.
- Extra thumb: Moles have an extra thumb on each of their front paws, which is unique among mammals. This extra digit helps the animal grip soil while digging and moving. It also helps anchor the paw in place.
These adaptations are crucial for moles’ survival in their underground environment, but they are not unique to moles alone. Other fossorial mammals, such as gophers, also have similar adaptations to help them move around in soil. However, moles are some of the most specialized diggers and have evolved a number of unique adaptations to help them thrive underground.
Having an understanding of the structure of moles’ forelimbs and claws can also help us better appreciate the animal’s behavior and lifestyle. For example, moles’ digging behavior is remarkably efficient, with the animal able to move several times its body weight in soil each day. These adaptations also allow moles to move quickly and quietly in their tunnels, which may help them evade predators or sneak up on prey.
Why Moles Have Strong Forelimbs and Claws
Moles are adapted to a life underground, and their strong forelimbs and claws are essential to their survival. The structure of their forelimbs allows them to efficiently dig tunnels and burrows in search of food, while the sharp claws provide excellent grip and traction on the soil.
The reason why moles have such strong forelimbs and claws is simple: it allows them to navigate and survive in their subterranean environment. Unlike many other animals that burrow underground, moles do not have powerful hind legs, meaning their forelimbs serve as their primary mode of digging and movement.
Moles also have a unique bone structure in their forelimbs that allows for strength and flexibility. Their ulna and radius bones are fused together, preventing rotation of their wrists and instead providing more forceful movement. Their wrist bones have a complicated arrangement of muscles and tendons that allow for powerful digging motion.
Compared to other animals, moles have the largest forearms and hands (measured by weight) relative to their body size. This adaptation allows them to easily burrow through soil, roots, and rocks. Their strong claws, with extra bones and cartilage, are also designed for strong and efficient digging. While other burrowing animals such as gophers and badgers have strong forelimbs and claws, none can compare to the strength and agility of moles.
Understanding the physical adaptations of moles helps explain their unique behavior and characteristics. For example, their strong forelimbs and claws allows them to be excellent at snuffling around for insects, grubs, and earthworms to eat. It also makes them more challenging to control if they become a nuisance in a garden or lawn.

Functions of Moles’ Forelimbs and Claws
As we delve deeper into understanding the anatomy of moles, it becomes increasingly evident that their forelimbs and claws are vital tools for their survival. Moles’ forelimbs and claws are specifically adapted to suit their subterranean lifestyle. These adaptations have enabled moles to carry out some of the most remarkable underground feats of any mammal. Let’s take a closer look at the different functions of moles’ forelimbs and claws that allow them to dig tunnels, move efficiently, and forage for food.
How Moles Dig Tunnels
Moles are known for their exceptional ability to dig tunnels. They have a specialized body structure that allows them to create elaborate tunnel systems underground. The forelimbs and claws of moles play a major role in digging tunnels.
| Feature | Description |
|---|---|
| Forelimbs | Moles have short and powerful forelimbs that are attached to a sturdy chest. The humerus bone of the forelimbs is rotated in such a way that it allows the forearms to move sideways. This motion enables them to dig tunnels efficiently. |
| Claws | Moles have strong, curved claws on their forelimbs that are designed to dig through soil. Their claws are also double-jointed, which means they can move backward and forward. This feature allows moles to burrow through soil without having to turn around in tight spaces. |
| Extra Thumb | Moles have an extra thumb on their forelimbs that is not visible on the surface. This digit provides extra support and stability to the digging process by anchoring themselves in the soil. |
Moles dig tunnels using their forelimbs and claws in a specific pattern. They first use their powerful forelegs to dig into the soil and create a tunnel. They then push the soil backward using their front legs and compact it with their bodies. Finally, they use their back legs to kick the soil out of the tunnel.
This process of digging tunnels can be repeated several times a day, depending on the mole’s needs. The intricate system of tunnels created by moles allows them to create underground dens, forage for food, and avoid predators.
It is fascinating to observe the digging process of moles using their strong forelimbs and claws.

You can also learn about mole snout behavior, which helps them to navigate and find their way around in their underground world.
How Moles Move in Tunnels
Moles are adapted for underground living and have unique characteristics that allow them to move effectively in tunnels. Strong forelimbs and claws play a crucial role in their locomotion. How exactly do moles move in tunnels? Let’s take a closer look.
| Movement Method | Description |
|---|---|
| Swimming | Moist soil is more pliable, so moles can use a swimming motion to move through it. |
| Gallop | When moving through drier soil, moles use a galloping motion, where they push off against the tunnel walls to propel themselves forward. |
| Backward Movement | Moels can move backward in tunnels as easily as forward and often exit their burrow backwards. |
Their forelimbs provide the force needed to excavate soil and push it behind them, while their powerful shoulders allow for a wide range of movement. Moles can swim through moist soil, and gallop through drier soil. They can also move equally as easily backwards as forwards in tunnels. This ability allows them to exit their burrows quickly and smoothly in case of any danger.
The unique combination of strong forelimbs, digging claws, and shoulder joints enable moles to move effectively through the tunnels they dig.
How Moles Forage for Food
Moles are insectivores, meaning that they mainly feed on insects and other small invertebrates. They can eat up to 80% of their weight per day, and their diet consists of earthworms, beetles, grubs, and more. But how do moles locate and capture their prey underground?
1. Sense of smell: Moles have a highly developed sense of smell, which allows them to detect the scent of prey. They use their long snout to move soil around, exposing insects or other prey.
2. Touch: Moles also have very sensitive whiskers, which they use to feel their way around tunnels and locate prey. The whiskers contain touch receptors that are used to navigate in dark or cluttered environments.
3. Hearing: While moles have poor eyesight, they have a keen sense of hearing. They can detect vibrations in the ground made by the movement of prey or other moles. Their ears are internal, so they can’t be seen, but they are very efficient at picking up sound waves.
Once they locate their prey, moles use their strong jaws to capture and kill it. Their teeth are sharp and pointed, which makes them perfect for catching and holding onto insects.
Fun fact: Moles have a ‘worm larder’ where they store live worms to eat later.
Moles’ strong forelimbs and claws play an essential role in their survival. Through their digging and movement, moles are able to build complex tunnel systems and forage for food efficiently.
