Astroglypha passiflora Downey, 1971 n. comb. Figure 8A–E Downey 1971: 49; 1973: 65; Clark & Downey 1992: 283, 284; A.M. Clark 1993: 354 (checklist). Taxonomic discussion. The specimen observed below is the first sampled from the eastern North Atlantic and represents an atypically small individual (R=0.5). Although only single papular pores are present, the R:r ratio and other features imply growth related characters rather than the presence of the Pacific species in the North Atlantic. In situ v ideo images of this species were captured by the NOAA ship Okeanos Explorer during the Oceano Profundo expedition in April 2015. Both images showed this species on limestone substrate adjacent to sponges, which are a possible prey item. Occurrence. Irving Bank, North Atlantic .
