For the last day of International Cephalopod Awareness Days: Cheers to the cephalopods that once reigned our ancient seas! 🎉
Thanks to the fossil record, more than 17,000 species of extinct shelled cephalopods have been identified, like the three ammonites in the photos above. Compared to the 800+ shell-less species alive today, the ocean used to have one shell of a lot of cephalopods!
