Update: Have you seen Dissecting Organs from the Deli? One time a parent had a butcher who gave her cow organs to dissect. They are unusually large.
Specimens for dissection are expensive. How do you get more from the dissections? First, use coloring pages to examine the parts. Here and here are sea star or starfish pages. Use online images. Make sketches of exterior and interior. Label everything! Talk about similarities and differences between the crayfish and grasshopper. In fact, ideally dissect the crayfish and grasshopper side by side. Label all of their appendages. How are they similar? Endoskeleton? Carapace? How do the appendages function? The more details the better.
