Comments: Mature and immature specimens were captured by bait traps on the sea floor; apparently benthic.  This is observed to swim searching for food fallen on the bottom and frequently to stay on the acrylic glass or walls of a tank using the ventral disk from individuals on display at Tokyo Sea Life Park.  Captured together with A holosaurid (<i>Aldrovandia affinis</i>), a psychrolutid (<i>Ebinania vermiculata</i>), and 2 zoarcids (<i>Ericandersonia sagamia</i> and <i>Japonolycodes abei</i>) in the same traps in Sagami Bay, indicating the likelihood of their sharing similar habitat.  Females have an ovipositor in the abdominal cavity and it is everted to outside the body when the abdominal cavity is pressed (Ref. 75204).
