This week we are celebrating cephlapods. Not sure what they are? Cephalopods are a group of exclusively marine mollusks that include squid, octopus and nautilus. They are closely related to snails, slugs and clams. Let’s be honest, you might be most familiar with them on your plate. These intelligent but vulnerable invertebrates are fascinating. They are represented in fossil records as long ago as 500 million years. If I had to pick, I’d say squids are my favorite 8-legged species, and not just because this is Squidturday. Squids defend themselves by being agile and fast as well as releasing sepia, often referred to as ink.
