This closeup of the head shows the eye turret, the proboscis (top left), the chelicerae (chelifores) next to the proboscis which are two-segmented and end with a knob rather than a chela, the basal segments of the palps, and the coxae of the first several legs. Note that there is no finger-like projection on the dorsodistal part of the coxa of the first leg.
In this closeup of the posterior body, the stub-like abdomen projecting from the thorax can be seen. Several algal cells are adhered to the leg in the lower right.
Achelia latifrons found on an Epiactis prolifera anemone at Cape Flattery. The distance from the tip of the proboscis (top left) to the tip of the abdomen (bottom right) is 3 mm. Total leg span is 11 mm. (Photo by: Dave Cowles, July 2014)
