Otters are a keystone species whose special adaptations, from physiology to eating habits, directly and indirectly effect the marine environments in which they thrive.
What factors have allowed sea otters to make a comeback and thrive in Glacier Bay and how will that affect the marine ecosystem?
Students will know ...
