This oblique view of the head shows the posterior eyes, which are visible dorsally, plus the anterior pair of eyes which are covered over by a flap of the prostomium. The two lateral prostomial antennae are seen to be inserted ventral to the median antenna. The anterior elytra were removed for this view.
Harmothoe imbricata, about 3 cm long. A few of the anterior elytra have fallen off this individual, revealing the segments underneath. This individual was living within the tube of another polychaete in Fidalgo marina. (Photo by: Dave Cowles, July 2009)
