The estuary stingray, also called the estuary stingaree or brown stingray, is a species of stingray in the family Dasyatidae. Endemic to eastern Australia, it typically inhabits shallow, mangrove-lined tidal rivers, estuaries, and bays in southern Queensland and New South Wales. This yellow-brown to olive ray grows to at least 93 cm (37 in) across. It has a diamond-shaped pectoral fin disc and a mostly smooth, whip-like tail bearing both dorsal and ventral fin folds. It can additionally be identified by its long, narrow nostrils and the row of thorns along the midline of its back.
Hippocampus coronatus, commonly known as the high-crowned seahorse or crowned seahorse, is a species of fish of the family Syngnathidae. It is endemic to the Pacific coastal waters of Japan, where it lives among Zostera seagrasses. It can grow to lengths of 10.8 centimetres (4.3 in), but is more commonly 6 centimetres (2.4 in). Individuals feed mainly on small crustaceans such as gammarid amphipods and copepods, although this can vary by size, with smaller individuals consuming copepods while larger individuals feed on amphipods and mysids.

Doryrhamphus negrosensis, commonly known as Negros pipefish, flagtail pipefish, Masthead Island pipefish or Queensland flagtail pipefish, is a species of marine fish of the family Syngnathidae. It is found in the Western Pacific Ocean, from Borneo to Vanuatu and the Yaeyama Islands to the Rowley Shoals and the Great Barrier Reef. It lives in mud flats and reefs, both coral and rocky, where it is often associated with sea urchins. It is a rather solitary species which may be found in pairs or small groups. It inhabits depths to 9 metres (30 ft), and can grow to lengths of 6.2 centimetres (2.4 in). Although little is known of its feeding habits, it is expected to feed on harpacticoid copepods, gammarid shrimps, and mysids, similar to other pipefish, it may also act as a cleaner fish like other species in the genus Doryrhamphus. This species is ovoviviparous, with males carrying eggs before giving birth to live young. Males may brood at 4.3 cm.
