Cumaceans (Crustacea, Peracarida) associated with shallow-water hydrothermal vents at Banderas Bay, Mexico
Cumaceans mostly inhabit marine environments, where they play a crucial role in marine food webs and actively participate in the transfer between benthic and pelagic systems. Scientific interest in these crustaceans has been increasing, but is limited to certain geographic areas, which do not include extreme environments such as hydrothermal vents.Therefore, this study aimed to report the distribution of cumaceans in shallow-water hydrothermal vents at Banderas Bay and to identify the specimens present. Three sites were selected (20°44’54.7”N, 105°28’40.6”W; 20°44’54.8”N, 105°28’40.4”W; 20°44’54.9”N, 105°28’38.4”W) and each site was divided into three zones, based on sediment temperature. Through SCUBA diving, 27 sediment cores were collected. The samples were processed and identified in the laboratory. The families Bodotriidae T. Scott, 1901; Pseudocumatidae Sars, 1878; and Diastylidae Bate, 1856; were recorded and six morphospecies were identified. This work leaves a preliminary frame of reference for future studies related to the biodiversity of cumacean in Hydrothermal vents environments.
