Chemosymbiotic faunal communities of the Karambusel vent field (A-D), Mussel Cliff (E, F), and Edison Seamount (G, H). Karambusel: (A) focused, warm vent (~ 29 °C) with dense populations of syboglinids, Bathymodiolus mussels and Shinkaia crabs, (B) Shinkaia crabs, Alvinocarididae shrimps, Bathymodiolus mussels, gastropods (Phymorhynchus and Paralepetopsis), (C) Microbial mats on altered volcanic rocks with Lamellibrachia curly tube worms, Paralepetopsis limpets and Archinome hairy worms, (D) microbial mats on sediment with Desbruyeresia gastropods. Mussel Cliff: (E) Dense population of Bathymodiolus mussels on carbonate crust; Associated fauna are Munidopsis squat lobsters, Paraescarpia tube worms, Paralepetopsis limpets), ophiuroidea fam. indet., holothuria (Chiridota); Note the dispersed Paraescarpia tube worms with clusters of Leucolepas stalked barnacles in the background; (F) Similar faunal assemblage to (E) but occurring as an isolated patch around a small fluid outlet; Sabellidae feather duster worms are surrounding the Bathymodiolus population. Edison Seamount: (G) dense cluster of Calyptogena gen. inc. vesicomyid clams on volcaniclastic substrate, Alvinocarididae shrimps, Munidopsis squat lobsters, Leucolepas stalked barnacles and Bathymargarites gastropods are associated, (H) Close-up of the Spionidae ‘worm carpet’ populated by Alvinocarididae shrimps.
