Figure 8 in Sleeping with the enemy: unravelling the symbiotic relationships between the scale worm Neopolynoe chondrocladiae (Annelida: Polynoidae) and its carnivorous sponge hosts

Figure 8. Stable isotopic values (mean and standard deviation of δ15N and δ13C) of the different hosts (Acanella arbuscula and Chondrocladia robertballardi) and annelids (Neopolynoe acanellae and N. chondrocladiae) collected in this study. Zooplankton values correspond to a mixture of species of crustaceans (copepods, ostracods, amphipods, and cumaceans) and chaetognaths.
