Crayfish are an intermediate dissection specimen. Also known as 'crawdads', these animals are widely distributed around the world in lakes, streams, rivers, and creeks. Crayfish have an exoskeleton and a variety of well-developed organ systems. Unlike some of the beginning dissection specimens, in a crayfish, we will begin to see organs as we know them....fully functioning brains and hearts. 

At the beginning of class, we will review the dissection kit tools and their uses. We will also observe the external anatomy of the preserved crayfish before beginning the dissection. As the dissection begins, students can expect to observe the crayfish cephalothorax, stomach, gills, heart, intestines, nerve cord, green glands (rudimentary kidneys), and appendages.

Students need to have either taken Beginning Dissection or have previously used a dissection kit in order to take this class. If they have not, please take my Beginning Dissection class prior to this one. Dissection tools are sharp! Your student must be able to maturely handle these tools during class. 

Recommended Order of Dissection Classes:

Students also need to have their own dissection kit, preserved crayfish specimen, and a clean place to perform the dissection. Some students also prefer to wear gloves while dissecting as well. 

Please note, fewer numbers of students may result in a shortened class time. 

There will be no refunds issued for a student(s) missing class.
