Dissection is a great way to give students hands-on experience with marine organisms. The National Science Teacher Association (NSTA) supports dissection as "one of the most effective methods of achieving many goals outlined in the National Science Education Standards (NSES)." This dogfish dissection will be part of our ichthyology unit and give students a chance to compare bony fish with a chondrichthyan. It is important to note that sharks, in general, are being decimated, one study estimates 100 million sharks are killed every year. However, the shark we are dissecting, the Pacific Spiny Dogfish, are low-level consumers that are above target population levels according to NOAA fisheries. These sharks are very abundant and are taken mostly from bycatch (accidental catch when fishing for other target species). This activity will give students the opportunity to engage with a shark up close and personal and allow them to build a relationship with this beautiful group of organisms. This may inspire students to help these creatures' relatives in the wild and dispel harmful misconceptions about sharks.
