Creature Feature – Northern Anchovy

Even though anchovies are small in size, they play a vital role in the marine ecosystem. 

Northern Anchovies are small fish that are an essential part of the marine food chain, serving as a key food source for many ocean creatures. Despite being near the base of the food chain, they feed on microscopic organisms. To evade predators, anchovies swim in large schools—sometimes numbering in the thousands. With so many fish moving together in a tight cluster, it’s difficult for predators to single out and target one individual. 

Anchovy or Sardine? Many people confuse anchovies with sardines due to their similar appearance. Anchovies are often seen swimming with their mouths open to gather microscopic food. Sardines, on the other hand, have a distinctive row of black spots along their sides. Their schools tend to move in quick, darting motions, while anchovy schools form vertical funnels or swirling patterns.
