Skeletal systems are frameworks that support animal bodies, protect internal organs, and allow for movement. In this comparative anatomy lesson, students will learn about the three types of skeletons seen in the animal kingdom. They will then explore the difference between the exoskeleton and endoskeleton by comparing five animal specimens: the squid, the starfish, the dogfish, the pig, and the cat. Discussion of how the skeleton relates to that animal’s lifestyle will be included. In addition, students will handle and manipulate the discussed specimens.
