38,000 animals and counting

As the Academy approaches its one year anniversary in the new facility, it seems appropriate that our cuttlefish have begun laying eggs. After all, our opening last September was just the beginning. These dwarf cuttlefish (sepia bandensis) are located in the Water Planet exhibit. You’ll have to look carefully for them, since they are able to change color, and can be tough to pick out of their surroundings. There are two in the photo below, plus a large cluster of dark eggs. The species is native to reefs in the Indo-Pacific region, and they feed on small mollusks, crabs, shrimp and fish, using a pair of feeding tentacles.

On September 26-27, to celebrate the Academy’s first anniversary in our new building, we have put together a fantastic lineup of cultural music performances and live animal demonstrations (including big cats). This weekend also marks the debut of our new planetarium show Journey to the Stars. Click here for a full schedule of events.

  1. The cuttlefish are my favorite animals at the aquarium. How long do they stay in the egg before hatching? Will the baby cuttlefish be on display in that tank?

  2. Thanks for the great questions, Kathleen. Our biologists say it takes 2-3 weeks for dwarf cuttlefish to mature in the egg before hatching. The eggs can often be seen on display, but the babies are typically kept behind the scenes so they can be monitored more closely by aquarium staff.

  3. I second Kathleen’s comment! Cuttlefish are my favorite… bar none. I have a deep amazement and concern for these mysterious creatures, and i definitely recommend ordering the PBS NOVA show on cuttlefish (im sorry its not online for free, but at least the money supports pbs):
