Zebras like to roll in dirt several times a day, which helps reduce ticks and other parasites on their skin. Their rolling also helps the environment and other animals in the area. When zebras roll, they leave impressions in the dirt, displacing pebbles and leaving a layer of fine sand or soil. This creates a natural pool of water when the rainy season comes that retains moisture longer than in the surrounding areas. Thanks, zebras! 🦓 #Zebra #ZebraDay #InternationalZebraDay | Los Angeles Zoo
