polychaete worm

Description:

First half is a blue color with legs like a caterpillar, second half is red with paddle type things (the paddles look like they are small gills or the same structure as gills) instead of legs. It has two fairly large mandibles (if that's the right word for them) that come out of a large hole on its head.

Habitat:

It was found about a foot and a half away from the ocean front. In Valdez Alaska.
