Last Valentine’s Day, we teamed up with the @AquariumPacific, @calacademy, @sandiegozoo and the @SunStarLab to achieve an extraordinary conservation milestone: the successful spawning of #SunflowerSeaStars! ⭐ Check out our work featured in @NatGeo ⬇️ nationalgeographic.com/anima…

Saving the world's largest sea star from extinction just got interesting

Scientists are racing to save sea stars from extinction through breeding. Here's what they're learning about the different species—from arm-wrestling bat stars to bloodless blood stars.

As the temperatures drop, we know it’s harder to get out of your warm bed (or chrysalis). However, visiting our white morphos in the 85°F climate-controlled Osher rainforest might be worth venturing out into the cold.

This seagull definitely heard we’re looking for sea stars this month… All iNaturalist observations of CA sea stars count towards the 2024 Solstice Sea Star Search, but maybe avoid replicating this bird’s invasive approach. More at bit.ly/seastar24 © Ellyne Geurts

Low tides are coming, and it’s the best time of the year to go tide pooling! Use our app, bit.ly/TideFinder, to see when your nearby coastlines will be most navigable, and upload any photos you take to iNaturalist, to help with our #SolsticeSeaStarSearch 🌊🪸🐚⭐🧪

What would really happen if you filled the Roman Colosseum with great white sharks? We called Steinhart Aquarium director @SteinhartBart, on his vacation, to break down *that* scene from “Gladiator II.” (It did not go as expected.) 🦈🔱💯 @calacademy sfchronicle.com/totalsf/arti…

We asked a marine biologist about that ‘Gladiator II’ shark scene

Could great white sharks really live in the Roman Colosseum? We asked a San Francisco marine biologist to break down the most unbelievable action scene in “Gladiator II.”

Pinyon jay populations are declining drastically throughout the SW — despite living in an ecosystem that spans 100 million acres. Learn more about the relationship between a little bird & its favorite pinecone in @bioGraphic here: bit.ly/3AjWxYe 📷: Christina Selby

Last week, our @calacademy_ssi interns presented their research posters at the @SACNAS #2024NDiSTEM conference in Phoenix. 2 of our students, Keily and Dylan, took home awards for their posters! 🏆 Congrats to all of our interns! (Including the ones that used more than 3 words.)
