Herring is a tasty dish for both people and animals. Many birds, animals and fish hunt herring for a bite to eat. A school of herring is a large group of herring that swim closely together. One school may contain thousands of herring, and they move quickly when humpback whales swim straight through the group with their mouths wide open. This puzzle has 140 pieces and is a little challenging for both children and adults, since the pieces are similar. Be sure to study the picture closely to memorise the details before removing the pieces. It will then be easier to put them back together, and you can train your memory at the same time.
