The false boarfish (Neocyttus helgae) is a species of fish in the family Oreosomatidae (oreos).

[4][5] The false boarfish is dark grey in colour, with a maximum length of 30.5 cm (12.0 in).

It is diamond-shaped, with a protruding small mouth and large spiny rays present at the anterior edges of the fins.

[6][7] Neocyttus helgae is bathypelagic, living at depths of 915–1,829 m (3,002–6,001 ft) in the North Atlantic Ocean,[9] being found off Madeira and Ireland and in the Cantabrian Sea.

[10][11][12] The false boarfish feeds off zooplankton and raises its dorsal spine as a territorial display.
