How does the puffer fish hunt its food?

Answer 1

Like many auks, puffins eat both fish and zooplankton, but feed their chicks primarily with small marine fish several times a day. The prey species of the Atlantic Puffin include the sandeel, herring and capelin.[15][16] The puffins are distinct in their ability to hold several (sometimes over a dozen) small fish at a time, crosswise in their bill, rather than regurgitating swallowed fish. This allows them to take longer foraging trips, since they can come back with more food energy for their chick than a bird that can only carry one fish at a time. In August, children from Iceland walk around the neighbourhood with boxes to help puffins that land in dangerous spots.
