Are the things I circled like praying mantis legs? If so, it's a small spearer mantis.

No that is the top of its sucker mouth. Pretty bad pic I know ,its in a measuring spoon after I caught it. I have seen it on the glass and it looks just like a snails mouth. I have also seen it on my live rock. Thanks though and please if anyone has any info , links or anything that may help me id this please post
