Cool Starfish Dissection Lab

Hello boys and girls. Gather around. Today we're going to talk about dissecting starfish. But before we make any cuts, here's some contextual information about the starfish. Starfish are found on the sea beds of all oceans, typically about 20,000 feet below the surface of the water. They feed on invertebrates in the area, such as clams, oysters, sand dollars, and mussels. Some starfish may also feed on decomposing plants and animals or even coral. Starfish breathe through the tube feet in their arms by diffusing oxygen through their skin. Starfish also have eyes at the ends of each arm, but it is unknown what their purpose is. Now that  we've got some context, let's talk dissection. Take a look at the pictures below where we've opened up a starfish to show you its external and internal anatomy.

Now that you've seen the final product, watch this video to see how we did it!
