help identify cocoon

Jenneric222 · Feb 13, 2016

Had my saltwater tank for about a year now and normally through great sites like this I can identify things or find the answer to most of my questions but this time I have had no luck. Hopefully someone on here can help me. I have this ball like cocoon looking thing that has been on my rock for a while now and can't figure out what it may be. It is soft to the touch sand the color is white with some brown scales on it. It could be nothing at all but has had me searching for hours. Does anyone know what it might be?? I have attached photo. Thanks so much!

Maybe a sponge? Hard to tell from pic

Sponge times 3!

You have a FTS (full tank shot) of your tank?

Thanks everyone so much! Looks like a sponge wins! After some researching it does appear to be a Puff Ball sponge. Being new to this I had no idea that sponges could be hijackers too so I never even considered that. I am definitely learning something new everyday with this tank but I love it!!! It is so addicting! Thanks so much for all the help!
