Scalicus is a genus of marine ray-finned fish belonging to the family Peristediidae, the armoured gurnards or armored searobins.

Scalicus was first described as a monotypic genus in 1923 by the American ichthyologist David Starr Jordan with the newly described Peristedion amiscus, designated as its type species.

[2] Jordan did not explain the genus name's etymology but it may be from skallo meaning "hoe", an allusion top the shovel shaped snout of the type species.

[5] Scalicus armoured gurnards have no teeth in the upper jaw, a smooth lateral margin of the head.

[4] Scalicus armoured gurnards are demersal, deep water fishes which are found in the Indian Ocean from the eastern costa of Africa to Hawaii.
