Monthly Giving

Join the Otter Raft!

Did you know that a group of sea otters is called “a raft?” When floating at sea, otters hold hands or wrap themselves in kelp to stay connected, protected and supported. Their fluffy brown group looks like a floating raft.

Just like otters, we’re stronger when we stick together. It takes an entire community to support our marine environment. Join the Otter Raft!

When you join our Otter Raft community, your monthly gift will support the Seattle Aquarium’s longstanding conservation work and much more. Earth’s one ocean is facing many challenges. Together, we can make a difference for the ocean and the amazing diversity of animals that call it home!

Monthly donations: simple and easy

Set up a recurring gift and it will automatically process each month. You can easily change or stop your gift at any time. The best part? You’ll make an impact throughout the year in a way that works for your budget.

Take your support to the next level

All monthly donors receive special benefits—but if you give $30 or more per month, you’ll become eligible for the Friends of the Aquarium donor circle and its affiliated benefits. Join this community and meet other supporters at exclusive donor events.

Support the Seattle Aquarium

With your help, the Seattle Aquarium builds connections with our community to inspire conservation and curiosity for marine life. When you make an end-of-year gift by December 31, you'll be joining us in protecting our shared marine environment—now and for generations to come. Thank you!
