The sky gazers or star gazers (Uranoscopidae ( Gr .: "Ourannos" = sky, + "skopein" = to observe)) are a family of fish from the group of perch relatives that live in seas with a tropical and temperate climate on the sea floor at a depth of up to 500 m occurs.

Sky-gazers are coveted fine-fleshed food fish .


Sky-gazers have a beefy exterior, a slightly dorsoventrally flattened body and a large, broad and strongly ossified head. The mouth is extremely top, the lips frayed. Their name comes from the fact that they mostly lurk buried in the sandy or muddy ground and only the small eyes on the top of the head are visible. A powerful poison sting lies behind the gill cover. The gill cover hem is long, notched, and thus enables exhalation in the sediment. The body is covered with very small scales or has no scales. The sideline organ is high up, near the back. The pelvic fins are throaty and close together, they have one hard and five soft rays. The first, small, hard-radiating dorsal fin is always separated from the second, elongated one. Some species lack the first dorsal fin. The long anal fin has 12 to 18 soft rays. The caudal fin is straight or is slightly indented. Some species have more or less powerful electrical organs (originated from eye muscles). Some species use a worm-like extension on the inside of the lower jaw (mandibular valve) as bait to attract prey. To pack the prey, the head is raised strongly, for which the foremost vertebrae are differentiated accordingly.
