hitchhiker id

I bought some more lr last night and saw this thing that is actually living in a hole. I can not get a pic of it as it will not come out of the rocks.
Here is a description, it is either clear or tannish color, lives in a hole, it moves and is long like a centapede, it is about an inch or so long and seems to have somewhat of a tail like a shrimp, it looked like it had alot of legs, but again this was all seen behind some rocks and now he has been in his hole, hubby says he looks like a crab in the face.
Any ideas, safe or not? I have looked at all the hitchhiker pics and did not see anything like it.

sounds like it may be a mantis shrimp. bad bad bad. or it could be a pistal shrimp. I would put the rock in a bucket with a little water. see if you can get it t come put by adding a piece of shrimp. if it wont come out, try a fresh water dip.
