The Barreleye, Macropinna microstoma has a transparent head and tubular eyes (the green upwardly directed globes). It lives at depths down to 800 m. The footage was taken by an ROV (remotely operated vehicle).

The species occurs in northern Pacific waters.  About 11 species of barreleyes (family Opisthoproctidae) occur worldwide, with three species currently known from Australian waters;

  • Grimaldi's Barreleye, Opisthoproctus grimaldii
  • Glasshead Barreleye, Rhynchohyalus natalensis
  • Binocular Fish, Winteria telescopa.
