Hazeus profusus

Hazeus profusus is a small reef fish from the family Gobiidae, found in the tropical waters of the Western Pacific, including regions like Papua New Guinea, the Solomon Islands, the Philippines, and Indonesia. This species is characterized by its maximum length of 2.9 cm. Its body is generally tan to whitish on the underside with 5-6 diffuse brown saddles on the dorsal side. A notable feature is the five large rectangular dark-brown spots along the sides of its body, accompanied by numerous smaller dark-brown and white spots on the head and upper body. The third dorsal spine is the longest, and it typically has 10 segmented dorsal and anal rays, with 16-18 pectoral rays. Hazeus profusus inhabits sandy-bottom environments, where it exhibits a sand-dwelling behavior. The species is demersal, meaning it lives close to the sea floor. The body is covered with ctenoid scales, except for cycloid scales on certain areas like the prepelvic region and the base of the pectoral fins. The head is fully scaled, with a 'mixed' pattern of sensory papillae. This species is assessed as 'Least Concern' by the IUCN Red List. Divers encountering Hazeus profusus may find it in sandy areas, where its small size and coloration help it blend into its surroundings, making it a subtle but interesting find.
