In this view the ocelli (dark spots) can be seen on the radioles. The ocelli can sense light and dark, allowing the animal to pull rapidly inside its tube when a shadow passes over it.
In this view of the thoracic parapodia the neuropodia (above, directly facing the camera) can be seen to be short-handled, avicular uncini (or with no handles at all) that are in a straight or slightly sinuous line. The notopodia (below) have both long limbate and shorter spatulate setae. This is a view of the left side of the animal which is outside its tube. The animal's ventral side (smooth, white) is up in this photo.
Laonome kroeyeri in its tube. The tube is about 1 cm in diameter and 25 cm long. This individual was caught by otter trawl at about 75 m depth in the San Juan Channel. (Photo by: Dave Cowles, July 2008)
