Vivo cerca de un océano (There»s an Ocean in My Backyard!) [PDF ebook] 

The ocean covers about 70 percent of Earth. That makes it the planet’s largest biome! With millions of species of plants and animals living in it, this biome needs special care as climate change affects Earth. Readers learn about the five named oceans and where they are on a simple map. Important concepts from the science curriculum are introduced in age-appropriate language, including food webs, animal adaptations, and conservation. Full-color photographs of ocean life further emphasize the diversity and interconnectedness of the ocean biome.
