Seafood Surgery

Add to list Go to activity
In this hands-on activity, learners discover the similarities and differences between a vertebrate and invertebrate by dissecting a perch and a crawfish. This can be a very rich and time consuming (and messy) activity! Having a good set of diagrams or dissection guides is essential, as well as a sharp pair of scissors.
