Mammals
What animal has hands like shovels, fur like velvet, and builds an underground city while you sleep? It's the mole! These small, furry mammals spend almost their entire lives underground. Moles are incredible diggers that can tunnel through soil at amazing speed. They build complex networks of underground tunnels where they live, eat, and raise their babies. Most people have never seen a real mole-only the mounds of dirt they push up in yards and gardens. Let's dig into the secret world of moles!
Moles have round, tubby bodies with velvety dark fur! Their fur is special-it can lie flat in any direction. This lets moles move forward or backward through their tunnels without getting stuck. Most moles are dark gray, brown, or black. Their fur is so soft and smooth that people once used mole pelts to make clothing. Moles are about 5 to 7 inches long-roughly the size of a hamster!
A mole's front paws are its most amazing feature! Each front paw is like a wide, flat shovel with strong claws. Moles have an extra thumb bone that makes their paws even wider. Their powerful front legs and shoulders are built for pushing through earth. A mole's arms are rotated outward, with palms facing out-perfect for scooping dirt. They're like tiny, furry bulldozers!
Moles have tiny eyes and no visible ears! Their eyes are very small and covered by fur-some species can barely see at all. But moles don't need good eyesight underground. Their ears are just small openings hidden in their fur. What moles do have is an incredible sense of touch. Their snouts are covered in thousands of tiny sensors that detect vibrations, movement, and even electrical fields from prey!
Moles live underground in tunnels they dig themselves! Eastern moles are the most common species in North America. European moles are found across Britain and Europe. Star-nosed moles live in wet areas of eastern North America. Moles prefer areas with soft, moist soil that's easy to dig. Gardens, lawns, fields, and forest floors are all perfect mole habitats!
Mole tunnel systems are surprisingly complex! A single mole can dig up to 18 feet of new tunnel in one hour. Tunnel networks include shallow feeding tunnels just below the surface and deeper permanent tunnels. Moles build a special nesting chamber lined with dry leaves and grass. They also create "larders"-underground pantries where they store live worms for later meals!
Those lumps of dirt in your yard are called molehills! When moles dig deep tunnels, they push the extra soil up to the surface. A single mole can create several molehills in one day. The raised ridges you see running across lawns are shallow feeding tunnels just below the surface. Even though molehills can be annoying, moles actually help gardens by aerating the soil and eating pest insects!
Moles eat earthworms, grubs, and insects found underground! Earthworms are their absolute favorite food. A mole can eat its entire body weight in worms and grubs every single day. That's like a person eating 150 pounds of food daily! Moles also eat beetle larvae, ants, centipedes, and other soil creatures. Their constant eating keeps pest populations under control!
Moles have a clever trick for saving food! When they catch more earthworms than they can eat, they bite the worm's head to paralyze it. Then they store the living-but-helpless worms in underground larders. One mole larder was found containing over 470 earthworms! The worms stay alive and fresh until the mole is ready to eat them. It's like having a living refrigerator!
Moles need to eat constantly to survive! Their high-energy digging lifestyle burns calories fast. If a mole goes more than a few hours without eating, it can starve. This is why moles are active day and night, digging tunnels and hunting for food around the clock. They typically eat every few hours, taking short naps between meals!
Mother moles give birth to 3 to 5 babies called pups! Baby moles are born in a special nesting chamber deep underground. The nest is lined with soft, dry grass and leaves. Newborn moles are tiny, pink, hairless, and blind. They're about the size of a jellybean! Baby moles depend completely on their mother for warmth and milk!
Mole pups grow incredibly fast! Their fur starts growing within a few days. By 2 weeks old, they have a full coat of soft gray fur. Their eyes open at about 3 weeks, though they'll never see very well. Baby moles start eating solid food at about 4 weeks old. Mother moles bring earthworms and grubs to the nest for the growing pups!
Young moles leave home at about 5 to 6 weeks old! They venture above ground-one of the few times moles are on the surface. This is the most dangerous time in a mole's life. Above ground, they're vulnerable to cats, owls, hawks, foxes, and snakes. Young moles must quickly find soft ground and start digging their own tunnel systems!
Moles are solitary animals that live alone! Each mole maintains its own tunnel system. They only come together to mate. If two moles' tunnels connect, they usually avoid each other or fight. Males may travel above ground during breeding season to find females. Moles can breed in their first year of life. In the wild, they typically live 3 to 6 years!
Moles are some of the most specialized mammals on Earth! They've spent their entire existence adapting to life underground. Every part of their body is designed for digging, tunneling, and hunting in the dark. Moles show us that amazing animals can thrive in places we barely know exist!
Moles are actually great for gardens and ecosystems! Their tunnels aerate the soil, which helps plant roots grow. Their digging mixes nutrients throughout the soil. Moles eat huge numbers of pest insects and grubs that damage plants. While molehills might look messy, the moles beneath them are doing important work for the health of the soil!
The star-nosed mole shows us how incredible animal senses can be! Its nose tentacles are the most sensitive touch organs in any mammal. It can detect and eat food faster than any other mammal. And it can smell underwater-something scientists didn't think was possible! The star-nosed mole proves that there's always more to discover about the natural world!
Moles remind us that an entire world exists beneath our feet! Millions of moles live out their lives just inches below the surface, and most people never see them. Their hidden world of tunnels, nesting chambers, and worm pantries is just as fascinating as any habitat above ground. The next time you see a molehill in your yard, remember the amazing little engineer that built it!
