from what I can see it looks like a cucumber of some kind...
there are many kinds of them and they each have different patterns of color and texture.
for example a "Sea Apple" is a Cuc' and they are related to starfish -- they all have 5 "sides" and some can put out feet on each side.
can you get a closer picture in focus?
the mouth end -- is it waving feeders in the water or cleaning surfaces ?
some like the sea apple are filter feeders.
others are sand feeders.
