Collecting Echinoderms

Echinoderm

If you are adventuring through our brand new unit, Taxonomy of Living Things: The Five Kingdoms of Life, meander with me for a moment…

Echinoderm? Whoever said, "It's all in a name," sure got it right. Echinoderms got their name because they are spiny-skinned marine animals. They possess radial symmetry, and many possess 5 arms (or multiples of 5). Sounds oh so scientific, but we've all seen these animals- sea stars, urchins, and sand dollars. 

 
Why not begin an echinoderm collection like we did to get a closer look?  
 
It's easy to collect real echinoderms if you live near the ocean. But if not, you can purchase the skeletons of these familiar creatures easily enough online. 
 
With a collection you can observe intricate details and similarities between species. You can also observe dissimilarity. You can record your observations with drawings and notes in an observation journal. So have a look see, you'll be glad you did. And after you do, explore the poetic possibilities here.
