Physico-chemical parameters and locality of assemblages are also identified for a black smoker assemblage (based on “Black & White”). Mega- and macro- fauna were identified using high-definition video and mosaic imagery, and were taxonomically verified from ROV-collected voucher specimens. ++, Abundant; +, present; (+) occasionally present; – absent.
