still cant tell!

[umbrellacorp]

i still cant tell if this is a majano or an urchin. In a little over a month its almost quadrupled in size. It moves around on the live rock a lot and hides in holes. Ive been talking to Jenn about it.. next time it comes out im going to try to grab it and see if i can pull it off the live rock. Can Majanos sting?

If it moves around it's likely an urchin. All the pix it seems to be in the same spot.

Why not just pull the rock out of the tank and take a closer look?

You won't feel a mojano if it tries to sting - the skin on your hands is too thick for it to do anything.

If it's an urchin, it's probably too small to pick through the skin on your hands either - but it's more likely to stick you if you try to remove it with your fingers.

Get a tweezer. Pick it off. If it's squishy and gelatinous it's a mojano. If it's crunchy and hard, it's an urchin.

My $2 still says it's an urchin.

This "thing" is entirely lacking the oral disc of the typical anemone, so I am ruling that out...

its in its hole right now.. the reason i cant accept that its an urchin is because it doesnt have spikes everywhere. it is definitely hard i just poked it again in its hole. i guess its just some kind of urchin i havent ever seen before.

Urchins don't have to have spines everywhere. They don't even have to have spines at all. Sand Dollars are a type of urchin, and they don't have the typical spines you think of as relating to other urchins.

Hard to tell from the pic's but it looks kind of like a Pencil Urchin to me.

Not a majano.

poke, it. Is it soft or hard?

Looks like a baby spiny or pencil urchin. Hope your rock is secure. Once it gets big, it will knock loose stuff around. I like mine best in the sump:yes:

Oh ok I didn't know that. I always wondered about people keeping sand dollars but I think that's about impossible isn't it? Next time its out ill pick it off with some tweezers. Thanks guys.

yep it just came back out... i touched it with my finger its definitely hard. I tried to pull it off with some tweezers but it wouldnt let go and i didnt want to forcefully pull it off and kill it. So ill let it be and see what kind of urchin it grows up to be.

i think its a Arbacia punctulata (purple urchin)
