Why Do Cephalopods Make Ink?

The most wonderful time of the year has arrived: Cephalopod Week, Science Friday’s annual tradition of spotlighting all things octopus, squid, and cuttlefish.

One of the many things that make cephalopods special is their ink. What’s it made of? Why do they shoot it at their predators? And why did they evolve this incredible skill?

To talk all about inking, guest host Annie Minoff is joined by Dr. Lauren Simonitis, research and biological imaging specialist at Florida Atlantic University.
