Who do eels harm?

Eels can harm various species, including fish, by preying on them or competing for food resources. Some eels, like the European eel, can also be affected by human activities, such as habitat destruction and pollution, which can harm their populations and ecosystems. Additionally, certain species of eels can be venomous or have sharp teeth that can injure humans if provoked. Overall, their impact is primarily on other aquatic organisms and ecosystems rather than direct harm to humans.
