The Truth About That Fish That Climbs Into Urethras

The video explores the myth of the candiru fish, which is said to swim into human urethras. This tale, originating from 19th-century explorers, is debunked by scientific research showing that the fish is not attracted to human urine and cannot physically enter a urethra. The video discusses a 1997 incident that claimed a candiru entered a man's urethra, but this account is likely a hoax due to numerous inconsistencies. The video concludes that while the Amazon is dangerous, the candiru is not a threat to humans.
