Squid are found in every ocean in the world and are eaten by many different predators. They are also a very important food source for people around the planet. Students will study internal and external squid adaptations: its structure and how all the parts function together to allow the squid to survive in its environment. Discussions can focus on squid adaptations and ecology, or the properties of organs, organ systems and specialized tissues/cells, depending upon class goals. High school students will dissect with greater independence and will create models to show flow and hierarchy within organs and organ systems.
