The Hawaiian Knifefish, also known as the sharp-headed wrasse, is a marine fish endemic to the Hawaiian Islands. It inhabits lagoons with sandy substrates, typically found at depths ranging from 5 to 119 meters. However, most sightings occur at depths shallower than 40 meters. This species is part of the Labridae family, known for their diverse and colorful wrasses. Hawaiian Knifefish are piscivorous, meaning they primarily feed on other fish. They exhibit benthic and benthopelagic behaviors, often found near the seabed or in mid-water columns. During breeding, they are oviparous and form distinct pairs, a common reproductive strategy among wrasses. Divers encountering the Hawaiian Knifefish might notice its preference for sandy-bottom habitats within lagoons. Despite being a predatory species, it poses no threat to humans and is considered harmless. The species is classified as Least Concern on the IUCN Red List as of the last assessment in 2009.
