Question! Tuxedo urchin do be crazy...

[BuddyBonButt]

So right now, my urchin climbed my glass and I'm currently wondering... how.

How does he attach himself to the glass? I thought that maybe he has a foot by its mouth but then I saw his mouth faced up to the surface (I was feeding him nori) and realized he's gripping the glass with his side.

Does he have feet on all sides of him allowing him to walk however like Spiderman??

Urchins do be crazy...

Tube feet, like little suction cups. Same type of feet starfish have. In your picture, its the clear protrusions that extend past it's spines.

Keep watching it move, you'll see the feet move as it moves.

Wait till you find sometimes 50-60 little round balls and think what they hell are they ( spoiler alert ,there urchin poo) underneath where he grabs onto glass/rocks is mouth and on top of urchin his bum ha ha

But yeah urchins are super cool

I think I may have, I asked to hold one at my LFS but it was a baby and that's the one I picked up. I was afraid of the big one lol. I plan to carefully pick him back up when he's bigger.

Next fear to overcome are the cleaner shrimp. I just let one for like a millisecond touch my hand and I tried so hard to not freak out. I'm getting there though

(Childhood trauma with shrimp )

Whaaat. I love this hobby. Glad I chose marine biology for school. Can't say I've ever been itching to watch an animal poop before but here we are... lol

Oh yeah... I was very much warned about that

I knew their beak(mouth) was at the bottom, but thought they are similar to coral where their mouth is their anus too. You learn something new every day!

Yeah me too. Figured it was a double feature hole. Turns out it's just an encore

 

[ying yang]

Yup there you go,urchin pooing lol

 

[BuddyBonButt]

Mine hasn't been pooped yet and I've had it for like 4 days. Is it not eating enough? How often do they do the deed??

 

[homer1475]

I've had mine for years, and I have honestly never seen it poo. I have seen the little balls in the sandbed, and knew it was urchin poo, but have never actually seen him do the deed

Well I have white sand so I don't think I'll see a pile any time soon... or maybe 80 pounds of urchin poo

Couldn’t have a tank without one

Absolutely beautiful

Don't expect to see any coralline growing, it's like candy to urchins.

Also if you see it climbing the glass, strip a piece of nori and wedge it between it and the glass, and watch it eat!

I have white sand too, you can see the piles of white balls.
