The terrible legend about silurus glanis cannibalism can be traced back to15th century, but in 2008, a big fish attacked people in Schlachtensee Lake outside Berlin, and a young man and two girls were attacked while swimming in shallow water near the shore. Some silurus glanis were caught in Russia, and they had human remains in their stomachs. Many people believed that the attacker was a 5-foot-long silurus glanis. But most experts believe that the victims drowned before being swallowed by catfish, which only ate human bodies. However, during their mating season, silurus glanis showed extremely aggressive behavior, so it is believed that if someone entered their territory at that time, silurus glanis would attack humans.
