Three-fourths of the world’s surface is covered with water, and just below the surface of oceans, lakes, and rivers, are complex webs of plants and animals. In a series of nonfiction articles, readers will learn about the ocean zones of the marine biome, and the zones of the freshwater biome.These articles are accompanied by an aquarium tour led by Claire Lake, the Snap City Aquarium docent who will educate readers about various life forms residing deep in the ocean, among coral reefs, and in and around freshwater biomes while visiting the Small-Fry Pavilion, Coral Reef Exhibit, and Amphibian World.
