Rarely caught in trawl (pelagic and benthic) and longline fisheries. The Australian specimen was probably taken by otter trawl targeting prawns (not known if taken on/near the bottom or in midwater) (McGrouther 2001). The Azores specimen was taken by pelagic trawl (Zidowitz et al. 2004) and the Brazilian specimens were collected from longline fisheries operating out of Santos in the south of the country. One specimen was retrieved attached to a hooked blue shark Prionace glauca (Sadowsky et al. 1988, Amorin et al. 1998).
