Spotted Paca

Fascinating facts about the Spotted Paca

• A spotted paca can hold a full mouthful of fruit inside cheek pouches so large they extend back past its shoulders — then retreat to a burrow and spit the load out later, like a furry squirrel with a storage locker the size of its head. This ferrying system lets it exploit fruit trees faster than competitors can strip them, turning an afternoon bonanza into a week of meals.
• When a paca is cornered, it doesn't fight or flee in a straight line. Instead it bolts toward water and dives to the bottom, staying submerged for up to an hour by slowing its heart rate and metabolism to near-hibernation levels. A jaguar or caiman waiting on the bank will eventually give up and leave a meal uneaten.
• The spotted paca's alarm call is a low-pitched drumming sound made by rapidly striking its hind feet against the ground — a vibration that travels through soil and roots so effectively that other pacas up to 100 metres away feel the warning through their feet before they hear it. It's an entire language written in vibrations, invisible to predators watching from above.
• A paca's back teeth never stop growing throughout its 13-year lifespan, and each tooth is shaped like a cylinder with sharp ridges — a design that can pulverize the hardest seeds and nuts in the rainforest. Some seeds are so armour-plated that only a paca's jaw has the leverage to crack them open, making the paca a silent architect of forest regeneration.
• Unlike most rodents that scatter and breed year-round, spotted pacas form monogamous pairs that stay together for life and defend a shared territory of up to 60 hectares. Both parents guard the burrow and the single offspring born once yearly — a family model so rare in rodents that biologists still debate why a relatively solitary rainforest forager evolved such loyalty.

About the Spotted Paca

In the dappled shadows of the tropical forest, the spotted paca moves with quiet purpose, its large, dark eyes ever-vigilant as it navigates the underbrush with a gentle rustle of leaves. With each deliberate step, its sturdy legs propel it forward, the distinctive spots on its back blending seamlessly into the mottled landscape as it forages for the tender shoots and fruits that sustain it. As it pauses to sniff the air, its whiskers twitching with sensitivity, the paca embodies a serene and unhurried existence, a testament to the enduring charm of this unassuming, yet remarkable creature.
