As promised, today we have a challenge for you. We have placed three new organisms below. Each organism has several structural adaptations. We will send an Antarctic postcard to anyone who posts a unique structural adaptation that has not yet been posted to the forum. For each organism there is a link to the forum for that organism and your guesses. We can't wait to see what you observe.
Remember, each guess must include the structure and the function (job that structure does).
Sea Urchin (Sterechinus neumayeri)
What structural adaptations do you see on these sea urchins?

Bonus: What behavioral adaptations do you see the sea urchins using in this photo?
