Description

 Golfingia vulgaris, like all sipunculid worms, has an unsegmented body consisting of an introvert and a trunk. The introvert can be withdrawn into the trunk. The mouth, which is on the end of the introvert, is surrounded by up to 60-150 tentacles in three or more circles. The trunk is at least three times as long as it is wide and is slightly shorter than the introvert. The introvert is covered by many dark brown stumpy hooks at the anterior end. These are arranged irregularly. Golfingia vulgaris may reach up to 20 cm in length. It is very variable in colour, from grey to whitish or yellowish brown.
