ea otters are an essential keystone species in a marine ecosystem. They help to keep down herbivore populations to keep kelp happy and they keep sea urchin populations down. Sea otters are mammals that live in oceans often around california kelp forests. They live in chilly waters but have no blubber (Picky Eaters, p.1). Instead they have a thick coating of fur. This fur is thought to be the thickest fur of any mammal. The kelp forests that they live in range in temperatures of 42- 72 degrees Fahrenheit and 5-20 degrees Celsius. These waters are nutrient rich allowing kelp to grow. One other thing that helps them to maintain a steady internal balance is their food consumption. Sea otters eat 20 to 30 percent of their body weight every day
