Dear Claude
You made me smile so much when I saw your eyes closed and sides of your mouth curl up. Thanks for being a part of my life for the last 26+ years. It's been an honor to grow up alongside you!
Love, Stephanie Spencer
Dear Kelsey Paulling!
Tim and I would love to visit the Cal Academy, after two years of our not having a chance, and have you personally show us what is exciting you! In the meantime say “Hi” to the penguins! !
Love, Melissa and Tim Snyder
Dear Academy of Sciences staff.
Thank you so much for all that you do. This place was apart of the magic I’ve witnessed when I first moved to this city and it’s a place I have such fond memories. I’m so happy that magic is back.
Love, a San Francisco citizen

Dear Claude and all your wonderful animal friends at the Academy,
I love you Claude, and I love all your amazing animal friends at the Academy. You are a touchstone for me, a treasure, and it's always a joy to see you when I visit. I've been coming to the Academy since I was a small child, many years ago. Now my adult children and I visit -- they adore you too! Take care, dear friend, and please know that you are often in our thoughts.
Much love, Melissa, Lizzy and James oxox

Dear Cal Academy Team (like, everyone),
I miss going to Cal Academy more regularly. As someone born and raised in San Francisco, it was (and remains) one of my favorite places to go (not just to learn about the world and all of the incredible animals, but also) to learn how to care for myself, my loved ones, and the planet. You might be wondering or asking how? Well, it's the way everyone pulls together to create an experience that encourages me to ask questions, be curious, and learn how to do my part to love and respect the planet by learning as much as possible about its inhabitants. From the facilities crew to the docents and tour guides to the scientists to guest services, I miss it all and love how you all take care of the ecosystem that is Cal Academy so that we learn how to take care of all of the other ecosystems outside of it. Sending you all love and I need to visit soon!
With lots of love, Dorothy
Dear Butterflies!
We have missed experiencing and seeing all of you and your wonderful habitat so much! We'll be there again as soon as possible to view your fragile loveliness.
Love to you all from all the Martin family
Dear James
We miss you and all your hungry animals of land and sea! We hope to be able to visit this year. Meanwhile keep up the great work!
Love, Mom and Dad
Dear Wende,
Thank you for being the penguin of my heart
Yours always, Kuno
Dear Sea Dragons,
I never visit the Academy without stopping by your beautiful home to say hello and see how you are doing. The closure was hard for everyone, and I'm sure it was hard for you as well. Watching you floating so gracefully in your tank, peering out at the guests, is something I have sorely missed. Can't wait to see you again!! P.S. Thank you to the dedicated staff who ensure the health, safety, and comfort of all the animals at the Academy, and especially for those who care for my wonderful Sea Dragons!
Love, Ellen Hanscom
Dear CAS staff,
I just want to thank you for all the countless efforts to keep the Academy well functioning during the time you were forced to close. Thank you to all the volunteers that fed the animals and the plants!! Thank you,
Dearly, William O'Farrill
