In March of this year, staff at the Vancouver Aquarium became the proud 'parents' of 400 tiny opalescent squid. These tiny cephalopods (a taxonomic group including squid, octopus and cuttlefish) will eventually reach an adult size of 1 foot; however, they are currently no bigger than a grain of rice. The video footage shows the squid babies eating and undertaking some rudimentary jet-propulsive movement - but the most spectacular part of the video is the showcasing of the chromatophores. Chromatophores are the pigment-containing cells of all cephalopods, and they allow these creatures to become camouflaged in almost any environment. Each pigment cell is directly connected to the nervous system and several muscle groups, which allows the squid to very intricately control both the amount of pigment and the specific colors used. Cephalopods are even capable of changing the texture of their skin! Enjoy this spectacular footage - courtesy of the Vancouver Aquarium.

Happy Monday!

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
