Phylum Annelida

Enter the segmented world of the bristleworms, found from the ocean’s depths to the high tide line. Sedentary terrebellids live under rocks in tubes, with a spectacular floral array of tentacles coming from their heads, while errant nereids meander about the mud. There are scyllid polychaetes so small, they may only be seen by teasing apart the tissues of sponges.
