Habitat and biology
''Caulolatilus chrysops'' is found near the bottom, at depths from , where it has been recorded on a substrate consisting of a rubble of shell and coral fragments. This species associates with '' C. microps'' and '' C. cyanops''. However this species is less numerous than either of those species, it is found greater depths than ''C. microps'', but at lesser depths than ''C. cyanops''. It forages on or just above the substrate and its diet is mainly crustaceans and other invertebrates, with some small fish.[ It is long-lived, able to reach 30–35 years old.]
