[2] The specific name nudifrons means "naked forehead" referring to the occipital and interorbital regions in juveniles and adults lack of scales compared to L. mizops which Lönnberg thought this taxon was a subspecies of.

[4] Males of this species are one of the most brightly-colored fishes of the Antarctic, with a warm orange-brown body color and brown bars, orange first and second dorsal fins, silvery white belly and a large black spot and short yellow bars on the dorsal fins.

[1] Lindbergichthys nudifrons mainly feed on polychaetes, amphipods and isopods as adults, however, fish eggs and shrimps are also taken.

Spawning takes place from April to October, with sexual maturity reached at 9 cm (4 in) SL.

As much as 6,886 eggs of up to 2.5 mm (0.1 in) diameter are laid under the cover of rocks and guarded by the male for about four months.
