The study of squid impulses has led scientists to discover the electrical language their brains use to communicate (Mehta, 2012). Squid often use this electrical language to change colors. Changing colors can signal any emotion a squid feels from fear to joy. Squid also have the ability to out-smart predators by mixing mucus and ink to eject a squid shaped ink cloud, which is triggered by a network of giant axons. They can be very curious as well, and are drawn to new objects that appear in their environments such as boats, bottles, and fishing hooks (Zimmermann, …show more content…

They are masters at manipulating and mimicking their environment, and their bodies are their main tools. Squid do not have a hard shells to protect themselves from predators, so they use their bodies for protection. They can change colors to blend into their surroundings with great accuracy, either to hide or to lure or confuse prey. Squid may also shoot rust-colored ink when threatened.
