The glassy sprat is a type of sprat fish. The fish, when alive, is translucent, so it gets the second word in its scientific name from the Latin word translucidus, meaning transparent, diaphanous. In animal classification the glassy sprat belongs to Osteichthyes, Clupeiformes, Clupeidae, Hyperlophus. The glassy sprat is native to Australia and mainly found in Australia. It is marked as NE because it has not yet been evaluated by the World Animal Protection. It is mainly used as an economical aquatic product. In ecosystems, they are at the bottom end of the food chain, feeding mainly on plankton, which are less aggressive and very vulnerable to other fish. Glassy sprat are tiny in size and translucent with a silvery streak that extends from its tail to just behind its head. As early as a hundred years ago, Australians harvested the glassy sprat in large quantities and it featured on the table as food for a long time. Due to its poor appearance, it is not a very good ornamental fish.
The striped stingaree is a common but little-known species of stingray in the family Urolophidae, endemic to shallow, inshore waters off southwestern Australia. Reaching 61 cm (24 in) long, this species is characterized by an oval, grayish to brownish disc with darker mask-like markings around the eyes and paired blotches at the center of the disc that are extended posteriorly into horizontal lines. Its nostrils have enlarged lobes on the outer margins and a skirt-shaped curtain of skin with a deeply fringed trailing margin in between. Its tail terminates in a relatively large leaf-shaped caudal fin, and bears a small dorsal fin just before the stinging spine. The rounded, flexible disc of the striped stingaree enable it to maneuver through the rocks, reefs, and seagrass that comprise its favored habitats. The International Union for Conservation of Nature (IUCN) has listed this species under Least Concern; it is seldom caught by fisheries due to its habitat preferences.
The masked stingaree is a common species of stingray in the family Urolophidae, endemic to southwestern Australia. It prefers moderately deep areas of sand or seagrass some distance from shore, though it can be found in very shallow water or to a depth of 115 m (377 ft).
