Dear biologists,
Thank you for taking care of penguins.

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
Dear Pierre and friends,
I miss seeing you all swim and play! During the pandemic I’ve been reading the book about you and your wetsuit to my 1 year old daughter. She loves it and I love sharing the magic, inventiveness, and and wonder that the Academy delivers. It’s a truly special place that is near to my heart!
Love, Marina Kohler
Dear Claude,
I love you Claude, you're the best. I drew you this picture of you.

To everyone at Cal Academy,
I miss everything about the California Academy Of Sciences and I miss attending NightLife. It’s been way too long since I visited. Can’t wait to return and visit again.
Sincerely, Hajji
Dear Butterflies,
Thank you for allowing me to visit your home in the rainforest. Your beauty always makes me smile. It has been difficult not seeing you this past year and a half. But thoughts of you during these troubling times warms my heart. I can't wait to see you again.
Love, Karen

To everyone at CatAcademy.
We visited from U.K. 2 years ago this week. The academy was one of our hilights in San Francisco and our visit was far more interesting and informative than we imagined it would be. The deliverance of science wonders of the world are sometimes hard to convey but we found the balance perfect!
Kind regards - Anne, Roddy & Damon
Dear Rainforest fish tunnel,
We love sitting on the benches to watch all the fish swim over head & search for the turtles as we enjoy a snack. We have even visited the Academy only to have lunch under the tunnel. Can't wait to see you again
Love, Liz & family
Dear Cal Academy Scientists & Staff
While I grew up just outside the Bay Area, visiting San Francisco was something my mother and I did all time growing up. I’ve always been a big fan of museums and I think Cal Academy’s interactivity with guests (and Claude, we can’t forget him!) was something that always kept me coming back. I love hands-on stuff and feeling like I’m included in what’s happening, so visiting has always been and will continue to be a blast. The California Academy of Sciences also greatly influenced how I see and value the planet and those living on it. I’ve just graduated this first week of June (2021) and my plan now is to move to San Francisco with my girlfriend so that I can study zoology or marine biology (I still haven’t decided). My dream job is to work with Cal Academy one day to inspire other children the same way the Academy’s expansive team has inspired me! Joining the team I revere so deeply is my next step in life, hoping I can make it come true!
With Love, Mac Tengonciang
