Piranha in aquarium for Saturday Critter

 

“Piranha” — the word itself felt serrated in childhood, passed around in playground whispers like a warning. It conjured murky rivers, thrashing water, and bones picked clean in seconds. I heard the stories again and again: a buffalo missteps at the riverbank, a cow wades too deep — and in a frenzy of silver flashes, the water boils, and all that remains is silence.

Years later, in Taipei, I stood before a glass tank at an aquarium and met the creature behind the legend. The piranha hovered in suspended stillness, its body compact and muscular, flanks gleaming like hammered metal beneath the artificial light. Most striking was the jaw — underslung, purposeful — lined with interlocking triangular teeth, each one razor-edged and perfectly aligned, designed not for chewing but for shearing. Even at rest, the mouth seemed tense with potential energy.

Native to the river systems of Amazon River and other South American basins, piranhas are schooling fish, acutely sensitive to vibration and scent. Contrary to the childhood mythology, they are not perpetual killing machines. Many species are opportunistic omnivores, feeding on fish, insects, crustaceans, carrion, and occasionally plant matter. The infamous feeding frenzies are typically triggered by scarcity, blood in the water, or confinement — heightened survival responses rather than constant savagery.

Yet knowledge did little to quiet the unease.

In the dim aquarium light, their eyes seemed to watch with a measured intelligence. They did not thrash or snap; they waited. Their stillness was more unsettling than chaos — a collective patience, as if the river itself had learned to hold its breath.

Childhood imagination had rendered them monstrous, all teeth and turbulence. Reality revealed something more precise: a fish exquisitely adapted to its ecosystem, efficient, alert, and disciplined. But even now, when I recall the old stories — the sudden churn of water, the vanishing mass of muscle and bone — I feel again that small shiver from years ago.

Some names never quite lose their edge.

Piranha in Taipei Aquarium for Saturday Critter

 

While visiting an aquarium in Taipei, I came face-to-face with a creature that’s as infamous as it is fascinating — a piranha. Nestled behind the glass of its tank, the fish hovered with a stillness that somehow made it even more unsettling. Its sleek, silvery body shimmered under the tank lights, but what truly drew my attention were its teeth.

Razor-sharp and tightly packed, the piranha's teeth looked like something out of a horror movie. Even from behind glass, they gave off a sense of menace. It wasn’t hard to imagine how they earned their reputation — built for tearing flesh with frightening efficiency, they seemed almost too intense for such a small creature.

Despite their fearsome appearance, I found myself captivated rather than afraid. There was something mesmerizing about the contrast between their calm, quiet movement and the violence their teeth implied. In that moment, I realized why the piranha has such a legendary place in the natural world — it's a perfect example of nature’s balance between beauty and danger.

It has been raining heavily in Swan Hill, and the inclement weather is expected to persist throughout the weekend. I have just completed watching the entire series The Penguin. It is a most riveting production, steeped in anguish and tragedy, and peopled with eccentric, often unpredictable characters.
