Macro video of Tripneustes gratilla

Grabbed this video of my urchin today, while it was eating some algae from the glass and thought it was interesting enough to share. Looks like something from another planet if you ask me

that's really cool! i have 3 urchins in my 75g reef. i notice the back glass will get quite a bit of algae on it and then one day, it'll just be gone. awesome critters!

Yes. Very awesome indeed
I have an older video in poorer quality of the same urchin scarping off coraline algae. If you turn up the sound you can actually sense the scraping sound
