Sea Otter Awareness Week

From being hunted to near extinction in the 18th and 19th centuries, to being threatened by oil spills in the 1980s, sea otters have endured many threats to their survival. Sea Otter Awareness Week (the fourth week in September) is a time to recognize this keystone species and highlight the important role they play in maintaining balance in the ecosystem.

How You Can Help


Teach: Sea Otter Educational Materials

Are you a teacher or youth group leader looking to explore sea otter biology and conservation with your class? Defenders of Wildlife has a variety of educational materials to help you teach the next generation of wildlife conservationists about these important marine mammals, including a full downloadable curriculum for grades 6-8, and a trunk of teaching aids. 


Contribute: California Sea Otter Fund

The California Sea Otter Fund allows residents to donate part of their income tax refund toward research that benefits the recovering sea otter population. These donations make it possible for scientists to monitor sea otter mortality and improve near-ocean habitats for sea otters. Defenders of Wildlife worked with California lawmakers to pass the legislation to establish this fund, and so far it has contributed to this vital research for seven years.


Celebrate: Sea Otter Success Stories

Defenders of Wildlife works tirelessly to protect sea otters and the marine habitats they rely on for survival. From eliminating a “no otter zone” created by the U.S. Fish and Wildlife Service, to helping establish sea otter conservation projects, we continue to fight for these animals that play such an important role in marine ecosystems.
