Class SIPUNCULIDEA

Introduction

After Edmonds (2000)
Members of the class Sipunculidea have the tentacles arranged peripherally, encircling the mouth. Introvert hooks, if present, are simple, thorn-like and usually not in rows. The spindle muscle is not attached posteriorly, except in species of Siphonosoma and Siphonomecus. The two orders within Sipunculidea are Sipunculiformes and Golfingiformes.
