Mackerel is a common name applied to a number of different species of pelagic fish, mostly from the family Scombridae. They are found in both temperate and tropical seas, mostly living along the coast or offshore in the oceanic environment.
Carpet sharks are sharks classified in the order Orectolobiformes. Sometimes the common name "carpet shark" is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae.

The longnose houndshark is a houndshark of the family Triakidae. It is found in the western Pacific off northern Australia and Vanuatu, between latitudes 9° S and 26° S, at depths between 250 and 475 m. It can grow up to a length of 75 cm.
The deepwater sicklefin houndshark or the darksnout houndshark, is a houndshark of the family Triakidae. It is found in the western central Pacific, in the Coral Sea off Queensland and in the waters off New Caledonia.
The sicklefin houndshark is a rare houndshark of the family Triakidae, endemic to Western Australia. The holotype was collected from a depth of 150 m. Its reproduction is ovoviviparous.
The western spotted catshark is a cat shark of the family Scyliorhinidae found only around southwestern Australia, at depths between 100 and 400 m. Its length is up to 60 cm. The reproduction of the western spotted catshark is oviparous.
The variegated catshark is a cat shark of the family Scyliorhinidae, found off New South Wales and Western Australia at depths between 30 and 200 m. Its length is up to 41 cm. The reproduction of this catshark is oviparous.
The blotched catshark is a catshark of the family Scyliorhinidae, the only specimen, the holotype, being found off West Australia at 144 m. Its length is 44 cm and its reproduction is oviparous.
The southern sleeper shark or Whitley's sleeper shark is a deepwater benthopelagic sleeper shark of the family Somniosidae found in the southern Atlantic, Indian, and Pacific oceans. It is known from depths of 400 to 1,100 m. Its length is up to 4.4 m (14 ft). It feeds primarily on cephalopods, especially squid and fish; its stomach contents also less commonly contain remains of marine mammals and birds. Based on its generally sluggish nature and the speed of its prey, it is thought to be an ambush predator. A 3.6-m-long female caught off the coast of Chile had a whole southern right whale dolphin in its stomach. This dogfish is sometimes taken as bycatch in the orange roughy and Patagonian toothfish fisheries; whether this poses a threat to the species is currently unknown.
The longtail seamoth is a species of fish in the family Pegasidae. It is found in Australia, Bahrain, China, India, Indonesia, Malaysia, Mozambique, Myanmar, the Philippines, Saudi Arabia, Singapore, Taiwan, Tanzania, and Thailand. This fish is used in Chinese medicine and in the aquarium trade.

Hemiscyllium galei, the Cenderwasih epaulette shark, is a species of bamboo shark in the family Hemiscylliidae. Together with H. henryi, it was only scientifically described in 2008 by Gerald R. Allen and Mark V. Erdmann. At present, H. galei is only known from depths of 2 to 4 metres at reefs in the Cenderawasih Bay in West Papua, Indonesia. The largest known specimen was 56.8 centimetres (22.4 in) long. It can be separated from its relatives by the combination of seven relatively large dark spots along the side of the body, white markings on the edge of its dark dorsal saddles and other scattered white spots on the upper side.
Campichthys is a genus of pipefishes native to the Indian and Pacific Oceans.
The tiger pipefish is a species of pipefish native to the marine waters around Australia at depths of from 2 to 27 metres. This species grows to a length of 29.6 centimetres (11.7 in) SL. This species is the only known member of its genus.
The ring-backed pipefish is a species of pipefish found in the waters of the Indian Ocean off the southern coast of Australia. It occurs on reefs in beds of red and brown algae down to depths of 15 metres (49 ft). This species grows to a length of 22 centimetres (8.7 in) SL. This species is the only known member of its genus.
Bhanotia fasciolata is a marine fish of the family Syngnathidae. It is found in coral reefs, tidepools, and muddy/silty substrates in the Eastern Indian Ocean and Western Pacific. It inhabits at a depth range of 3–25 metres (9.8–82.0 ft), where it can grow up to 9 centimetres (3.5 in). It is ovoviviparous, with the male carrying the eggs in a brood pouch until they are ready to hatch.
Campichthys nanus is a species of marine fish of the family Syngnathidae. It is known from its type specimens that were collected at Pinda, Morrumbala District, Mozambique in the Western Indian Ocean, although there have been unverified reports of its occurrence in the South China Sea as well. This species reaches maturity at 2.5 centimetres (0.98 in) and is one of the smallest tail-brooding pipefishes, with males carrying eggs before giving live birth. Habitats and feeding habits of this species are unknown.
Campichthys tryoni is a species of marine fish of the family Syngnathidae. Little is known of this species, but the specimens that have been collected were found on the Queensland coast off of northeastern Australia. It is a rare mainly tan coloured pipefish with brownish markings, it has a white blotch over the eyes, a pale patch above the operculum and it has small white dots along its back and tail. The males frequently show irregular dark barring along their ventral surface. This species is ovoviviparous, with males carrying eggs in a brood pouch until giving birth to live young. The largest known specimen is 7.2 centimetres (2.8 in) long, while males may brood at roughly 6–6 centimetres (2.4–2.4 in). The species was described by James Douglas Ogilby in 1890 from a specimen collected in Moreton Bay, Queensland in 1886 and the specific name honours his friend, Mr Henry Tyron, with whom he enjoyed a collecting trip in Moreton Bay. It is a listed Marine species in Australia under the Environment Protection and Biodiversity Conservation Act 1999.
Choeroichthys suillus is a species of marine fish of the family Syngnathidae. It is endemic to Australia, occurring from Perth, along northern Australia, to southern Queensland. It lives in coral reefs to a depth of 14 metres (46 ft), where it can grow to lengths of 6 centimetres (2.4 in). This species is ovoviviparous, with males carrying eggs and giving birth to live young. Within the reef it is found among coral rubble.
