Amid a heat wave warning in effect, a South American sea lion on Aug. 6 eats frozen mackerel to cool off at Seoul Grand Park in Gwacheon, Gyeonggi-do Province. The best way for animals to overcome the summer heat is using water and ice. The park's zookeepers fed nutritious food to animals that have lost their appetite due to the prolonged heat.
