Taxonomy and regeneration of a newly recorded Polychaete Capitella teleta (Annelida, Capitellidae) in the coastal water of Shandong, China
The polychaete species of Capitella are widely distributed in the China seas, however little is known about Capitella taxonomy, and specimens collected from China have been identified as Capitella capitata (Fabricius, 1780) for more than 50 years. C. capitata was considered to be Arctic and subarcti...
