Eunice Eunice aphroditois

Form:

Photo of a Eunice wormEunice is a long, multi-segmented, robust bodied predatory worm and one of the largest polychaetes in the world.

It has two eyes and five tentacles. Its unusual feeding structure, called a pharynx, or proboscis, turns inside out, like the finger of a glove, to capture prey. Sharp mandibles, at the pharynx end can give a nasty bite.

There are numerous body segments which look like joined-together rings. On the both sides of each ring is a pair of movement lobes called parapodia. Each parapodia is tipped with bundles of bristles, called setae or cirri.

"Para" means "like" and "podia" means "legs"..

Colour:

Overall colour is is dark purple-brown to red-brown, with a purple iridescence. There is a white ring around the fourth body segment.

References:

This species name is now in question. The common form in southern Australia is called Eunice aphroditois in most references, but Edgar is uncertain, and thinks it may be something else. Edgar is using the name Eunice tentaculata.
