Distribution: Various species inhabit NSW waters including the large-toothed and small-toothed Flounder that are found throughout as well as long-snouted and greenback flounder, found in southern NSW. They are commonly found in bays and estuaries on sandy or silty bottoms.
Size: These fish range in total length about from 34cm to approx. 55cm.
Characteristics: These fish are laterally flattened bottom dwellers with both eyes on one side. They have distinct colouration such as spots, irregular blotches and rings on one side of their body with the other being pale.
Confusing species: Flounder are often misidentified as sole.
Distribution – There are more than 20 species of leatherjackets found throughout NSW waters and, depending on the species, can be caught in estuarine, coastal and offshore waters to depths of 250m or more. In estuarine waters these fish are often found around artificial structures such as pylons and wharfs or are found near seagrass beds e.g. fan-belly, six spine and rough leatherjackets. In coastal and offshore areas they can be found on rocky reefs, sand/mud bottom or in sponge beds e.g. six spine, yellow-finned, black reef, velvet and chinaman leatherjackets.
Size – Are generally found under 1kg in weight but some offshore species can grow to 3kg.
Characteristics – Several features set leatherjackets apart from other fish species, these include: a small mouth with beak-like teeth, rough sometimes sandpaper like skin, small gill openings, and a single serrated spine on the top of the head that fits neatly into a groove. Most leatherjackets are considered opportunistic feeders and readily feed on many different items including algae, crustaceans, molluscs, fish and polychaete worms.
Confusing species - could be confused with Triggerfish, however these fish have a dorsal fin rather than a single, serrated dorsal spine.
