Introduction to Dissection for Anatomy Study

Crayfish are an excellent option for dissection because they represent a unique group of organisms called arthropods. Arthropods are the most diverse and abundant group of animals that have specialized anatomy like jointed appendages, exoskeletons, and body segmentation. Discover the adaptations among a diverse selection of marine life.

Understand Body Organization and Comparative Anatomy

Because of their specialized appendages, crayfish are the perfect specimens for students to learn the relationship between structure, function, and the environment. Crayfish make the perfect specimen for an introductory dissection experience because you can leverage more basic/safe tools during the dissection, like scissors. Students can observe the external anatomy of a crayfish, including the exoskeleton and structures such as the carapace, pairs of walking legs, cephalothorax, antennae, antennules, swimmerets, abdomen, cheliped, compound eyes, maxilliped, maxillae, cervical groove, uropod, telson, rostrum, and more.
