Southern Broad-footed Mole

Fascinating facts about the Southern Broad-footed Mole

• A southern broad-footed mole's front feet are wider than its head and studded with claws that point sideways — built not for digging down but for swimming through soil like it's water. The animal literally breast-strokes through the earth, pushing soil behind it rather than excavating tunnels, which means it creates minimal surface disruption. This swimming motion is so efficient that a mole can tunnel 15 metres in a single night, never surfacing.
• Moles are born with sealed eyelids that may never fully open in their lifetime. Their eyes, buried beneath fur and thick skin, have shrunk so much over evolutionary time that they're essentially useless — the animal instead navigates by touch alone, using sensory hairs called vibrissae that detect vibrations in soil the way a bat detects sound. In perpetual darkness, sight became ballast.
• A mole's metabolic rate is three times faster than a mouse of similar size, driving it to hunt almost non-stop: it must eat roughly half its body weight every 24 hours or starve within 12 hours. This relentless appetite means a single mole will devour thousands of earthworms and beetle larvae each year, making it a linchpin of soil ecosystem engineering — turning over and aerating earth as it hunts.
• The southern broad-footed mole's range barely overlaps with human settlements, which has kept it off most people's radar despite occupying the same landscape as millions of people across California, Oregon, and Nevada. This invisibility — spending nearly its entire life underground in moist soil where humans rarely notice — means its population dynamics remain largely unknown. What we don't see shapes what we don't protect.
• Male moles produce a pungent scent from glands along their flanks during breeding season, a chemical signal so powerful it can saturate a female's tunnel network and attract her from metres away underground. This fragrance highway works in three-dimensional soil space, where odour plumes branch and fade unpredictably — yet females navigate them with precision, finding mates in a world where sight would be useless anyway.

About the Southern Broad-footed Mole

In the shadowy realm of the underground, the Southern Broad-footed Mole navigates with ease, its powerful front legs and long, claw-like nails propelling it through the dense earth with a slow, deliberate rhythm. As it moves, the mole's sensitive snout twitches, detecting the faint vibrations of unsuspecting insects and worms, its prey in this subterranean world. With each gentle heave of its muscular body, the mole reshapes its surroundings, crafting a hidden network of tunnels and chambers that remain a secret to all but the most discerning observers.
