Not Just a Pretty Face
What makes sea otters so vulnerable to disturbance and why is it so important for us to protect them? Sea otters are the most recently evolved marine mammals and have a number of physiological characteristics that make them an easy target for disturbance by humans. Yet some of these same physiological characteristics, such as exceptionally high daily calorie demands, also make them critically important to our coastal ecosystem health. To learn more about the unique vulnerabilities of sea otters to disturbance and also about their status as ecosystem superheroes, explore the following pages.
