Gulf menhaden are filter feeders, which means they eat tiny plants and animals called plankton π¦ . They swim with their mouths open, filtering food out of the water. These fish have a special way of communicating! They make sounds by rubbing their bones together, which helps them stay in their large schools. Menhaden are also very important for many predators, like larger fish, birds, and even dolphins π¬. They can live up to 10 years in the wild, but many are caught by fishermen younger than that.
