a Skeletal motifs of deep-sea E. aspergillum, whose food particles shared similarity with oil droplets46,47. b Front and top views of bio-inspired VAF with bio-inspired hollow cylinder (BC) skeleton and flagellum-adsorbent. c Models of oil-capture matrixes for different skeletons, including solid plate (SP), solid cylinder (SC), grid hollow cylinder (GC), chequerboard hollow cylinder (CC), helical ridge-grid hollow cylinder (HC), and BC (more details in Supplementary Text 2). d–f Impact of skeletal motifs on (d) the flow pattern at supercritical regime, (e) the magnitude of flow velocity and (f) the pressure at discrete nodes in adsorption region under different Re numbers. Note: The thickness is 0.1 L for horizontal, vertical, and diagonal elements in the grids of GC, CC, HC, and BC. Source data are provided as a Source Data file.
