Never Swim Without Knowing About the Candiru Fish! Discover the Hidden Dangers of the Amazon!
Fundacion Rapala – The candiru fish, native to the Amazon rainforest, is a creature shrouded in mystery and fear. Known as the “vampire fish,” this tiny but potentially dangerous fish has earned a reputation that few are aware of outside the depths of the Amazon Basin. Despite its small size, the candiru fish is one of the most feared inhabitants of the Amazon’s waters—not because of its appearance but due to its parasitic habits and behavior toward humans. Before taking a dip in these exotic yet perilous waters, here’s what you should know about this fascinating and fearsome fish.
The Candiru Fish: What Is It?
The candiru fish, scientifically known as Vandellia cirrhosa, is a parasitic freshwater fish native to the Amazon Basin. Measuring only 2.5 to 5 cm (about 1-2 inches) in length, it is almost transparent, making it difficult to spot in the murky waters of the Amazon. The candiru primarily feeds by attaching itself to the gills of larger fish and consuming their blood, hence the nickname “vampire fish.” Despite its small size, the candiru is known for being particularly aggressive in its quest for a blood source.

Why Is the Candiru So Feared?
The candiru’s parasitic feeding mechanism doesn’t typically pose a threat to humans. The candiru has developed the ability to detect traces of ammonia and urea in water, chemicals found in fish gills and human urine. According to some reports, the fish may mistakenly enter the human body in search of a host. While these occurrences are exceedingly rare, they’ve contributed to the candiru’s alarming reputation among locals and adventurous travelers.
The Candiru and Human Interactions: Myths and Facts
For years, stories have circulated of the candiru swimming up the urethra or other bodily openings of swimmers. The idea that this fish could parasitize a human has turned the candiru into a near-mythical creature. Many scientists argue that while it’s theoretically possible, the chances of such an incident are extraordinarily low.
How to Protect Yourself from the Candiru
If you’re planning a trip to the Amazon, there are several precautions to consider if you intend to swim in the rivers. Wearing protective swimwear like snug-fitting swimsuits or swimsuits with additional coverage can also reduce the risk of a close encounter with the fish. Some experienced travelers and locals even advise against swimming in particularly murky or slow-moving water, where fish activity is higher.
