収集方法

Specimens were selected from across as many taxonomic groups as possible, with duplicates of similar morphotypes avoided; thus, the aim was to increase our understanding of megafaunal diversity. A total of 55 specimens were collected during different dives in three APEIs and three different geoforms (abyssal plain, seamount, and seamount slope), 14 specimens were collected from abyssal seafloor in APEI 1; 13 from abyssal seafloor, two from the seamount slope and six from a seamount in APEI 4; and nine from abyssal seafloor and 11 from a seamount in APEI 7. In situ photographs and/or video frame grabs of each specimen were captured, with parallel lasers for scale at 15 cm spacing. Megafaunal specimens were collected with the manipulator (‘Orion’), suction sampler, or push cores, depending on the characteristics of each specimen in order to best preserve morphological characters. Specimens collected with the manipulator were placed into the biobox receptacle, while those collected with the suction sampler were stored in a suction box. Collection data were recorded at the time of capture (e.g., date and time, ROV latitude/longitude, seabed water depth, ROV waypoint name).

Method step description:

1. After ROV recovery, specimens were transferred and maintained in cold (2–4 °C), filtered seawater until processed. Following Glover et al. (2015), all specimens were photographed, given a preliminary identification and assigned a unique voucher code (e.g., CCZ_020). A tissue sample was taken from each specimen for downstream molecular analyses, and stored in 95% non-denatured ethanol at -20 °C. Specimens were fixed in 10% borax-buffered formalin and transferred to 70% non-denatured ethanol after 48 h, except for sponges, which were kept frozen at -80 °C. After the expedition, specimens and tissue sub-samples were sent to the University of Hawai’i Manoa. Specimens were archived at the Natural History Museum, London (NHMUK), and the Western Australian Museum (WAM), following taxonomic inspection.
