Look at this guy!

I know very little about him but apparently he's a polychaete worm in the the Phyllodocidae family, also known as paddle worms. That means he's probably an active predator who wanders the sea floor in search of small prey.

Paddle worms range greatly in size and this one looks like he's on the smaller side of the scale.

Others get much bigger.
