Hawaiian Lizardfish

Synodus ulae

The Hawaiian Lizardfish, known scientifically as Synodus ulae, is a distinctive member of the lizardfish family found in the Pacific Ocean. It is characterized by its elongated body and fine barring on the head, with body bands that darken towards the tail. The red hue of these bands gives it the common name 'red lizardfish'. Unlike other lizardfish species, it has a higher lateral line-scale count and long dermal flaps. Typically, it has fewer peritoneal spots, averaging 11-12, which can help divers distinguish it from similar species. This species is distributed throughout the Hawaiian Archipelago, including both the main and northwestern islands, and extends to the Mariana and Marshall Islands. The northernmost sightings have been recorded near Yaku-shima Island in Japan. Hawaiian Lizardfish prefer shallow, sandy environments near reefs, often found at depths of 1 to 121 meters, with most occurrences shallower than 40 meters. They are demersal, meaning they dwell at the bottom, often camouflaging themselves in sand, coral, and rocks. As carnivores, Hawaiian Lizardfish primarily feed on fish. They are ambush predators, burying their bodies under the sand with only their heads exposed, ready to strike at unsuspecting prey. They are pelagic spawners, releasing eggs into the open water. According to the IUCN Red List, they are categorized as Least Concern.
