The longsnout boarfish (Pentaceropsis recurvirostris) is a species of marine ray-finned fish, an armourhead from the family Pentacerotidae. It is endemic to the temperate waters of the southern coast of Australia including around the island of Tasmania. It is found over the continental shelf at depths from 3 to 260 m (9.8 to 853.0 ft), though usually at less than 40 m (130 ft). It is carnivorous and its diet consists mostly of polychaete worms, brittle stars, and brown algae. It is trawled throughout its range, though is not a commercially important species and catch rates are low. [1] It is the only known member of its genus. [2]
The longsnout boarfish grows to a maximum length of 70 cm (28 in). It has a large, spiky dorsal fin with 10-11 spines and a slightly forked tail. Its snout is almost tubular with a small mouth. The fish is white in colour with two dark angled bands on both sides and another band running from the snout tip to dorsal fin.
The longsnout dogfish is a little-known deepwater dogfish, found in the Atlantic and Indian Oceans from Namibia to Mozambique and in the South Pacific off southern Australia and New Zealand.
The banded bellowsfish, banded yellowfish, banded snipefish, or bluebanded bellowsfish, is a species of fish of the family Macroramphosidae, found in southern oceans at depths of 35 to 1,000 m. Its length is up to 30 cm (12 in).
Pentacerotidae or armourheads are a small family of ray-finned fishes in the order Acropomatiformes. They are native to the Indian Ocean, western and central Pacific, and southwestern Atlantic. They are generally found at rocky reefs below normal scuba diving depths, although several species occur in low densities at shallower depths.
The longfin boarfish, also known as the blackspot boarfish, is a species of marine ray-finned fish, an armourhead from the family Pentacerotidae which is native to the coasts of southern Australia, Tasmania and New Zealand. It can be found over the continental shelf and the continental slope at depths from 25 to 540 m. This species can reach a length of 40 cm (16 in). It can also be found in the aquarium trade, and is currently the only known member of the genus Zanclistius.
The striped boarfish, also known as whiskered boarfish, Japanese boarfish, sailfin armourhead or whiskered armorhead, is a species of marine ray-finned fish, an armourhead of the family Pentacerotidae, which is native to the Pacific Ocean from the Hawaiian Islands westward to the coast of Asia and Australia. This is a reef-dwelling fish found at depths between 18 and 193 m. It can reach a total length of 90 cm (35 in). It is currently the only known member of the genus Evistias.
Pentaceros richardsoni, the pelagic armourhead, Richardson's boarfish or southern boarfish, is a species of marine ray-finned fish, an armourhead from the family Pentacerotidae. It has a wide distribution in the oceans of the southern hemisphere. It is commercially important as a food fish.
The graceful shark or Queensland shark is a species of requiem shark, in the family Carcharhinidae, found in the tropical Indo-Pacific, from the Gulf of Aden to northern Australia. It is a midwater species that has been recorded to a depth of 50 m (160 ft). A stoutly built shark growing up to 1.7 m (5.6 ft) long, the graceful shark has a short, wedge-shaped snout, large, sickle-shaped pectoral fins and first dorsal fin, and black tips on most fins.
The hardnose shark is a species of requiem shark, in the family Carcharhinidae, so named because of the heavily calcified cartilages in its snout. A small bronze-coloured shark reaching a length of 1.1 m (3.6 ft), it has a slender body and a long, pointed snout. Its two modestly sized dorsal fins have distinctively elongated rear tips. The hardnose shark is widely distributed in the western Indo-Pacific, from Kenya to southern China and northern Australia. It inhabits warm, shallow waters close to shore.
The creek whaler is a common species of requiem shark, and part of the family Carcharhinidae, endemic to northern Australia. It frequents shallow waters close to shore, including estuaries. This small, stocky shark usually grows to 1.0–1.3 m (3.3–4.3 ft) long and is brownish in color without conspicuous fin markings. It can be identified by its long snout, large, triangular pectoral fins, and large, anteriorly positioned first dorsal fin.
The spot-tail shark, or sorrah shark, is a species of requiem shark, in the family Carcharhinidae, found in the tropical Indo-West Pacific Ocean between latitudes 31°N and 31°S from the surface to a depth around 72 m (236 ft). This shark grows to about 1.6 m. It is fished commercially over much of its range and the IUCN considers it to be near threatened.
The Japanese bullhead shark is a species of bullhead shark in the family Heterodontidae found in the northwestern Pacific Ocean off the coasts of Japan, Korea, and China. This benthic shark occurs at depths of 6–37 m (20–121 ft) over rocky bottoms or kelp beds. Measuring up to 1.2 m (3.9 ft) long, it can be identified by its short, blunt head, two high dorsal fins with anterior spines, and pattern of irregularly shaped, vertical brown bands and stripes. The Japanese bullhead shark is a docile, slow-swimming species that feeds mainly on shelled invertebrates and small bony fishes. Reproduction is oviparous, with females laying spiral-flanged eggs in communal "nests". This species is of little interest to fisheries.
The weasel sharks are a family, the Hemigaleidae, of ground sharks found from the eastern Atlantic Ocean to the continental Indo-Pacific. They are found in shallow coastal waters to a depth of 100 m (330 ft).
The blind shark is one of two species of carpet sharks in the family Brachaeluridae, along with the bluegrey carpetshark. Found along the coast of eastern Australia, this nocturnal, bottom-dwelling species is common in rocky areas and seagrass beds from the intertidal zone to a depth of 140 m (460 ft). It often roams in tidal pools where it may be trapped by the receding tide, and can survive for an extended period out of water.
Prognathodes aculeatus, the longsnout butterflyfish, is a species of butterflyfish found in tropical West Atlantic waters. It is also known as the butterbun, the Caribbean longsnout butterflyfish or Poey's butterflyfish. This species should not be confused with the banded longsnout butterflyfish.
The deepbody boarfish, or robust deepsea boarfish, is a species of marine ray-finned fish belonging to the family Caproidae, the boarfishes. This fish is found in the warmer waters of the Atlantic, Indian and Pacific Oceans.
The Indonesian angelshark is a rare species of angelshark, family Squatinidae, known only from a few specimens collected from fish landing sites in southern Indonesia. It is thought to inhabit the deep waters of the continental slope. Reaching at least 1.34 m (4.4 ft) long, this species has a flattened, ray-like shape and a well-developed tail and caudal fin. It is characterized by the absences of fringes on its nasal barbels and thorns down the midline of its back, as well as by its relatively plain grayish-brown dorsal coloration with dark saddles beneath the dorsal fin bases and a black leading margin on the underside of the pectoral fins. The International Union for Conservation of Nature (IUCN) has classified it as Critically Endangered due to significant fishing pressure.
Heniochus chrysostomus, also known as the threeband pennantfish, threeband bannerfish or pennant bannerfish, is a marine ray-finned fish, a butterflyfish from the family Chaetodontidae. It is found in the Indo-Pacific region.
Capros, the boarfish or Zulu fish, is a monospecific genus of marine ray-finned fish belonging to the family Caproidae. Its only known species is Capros aper. The boarfish is found in the northeastern Atlantic Ocean and the Mediterranean.

Lepidotrigla papilio, the spiny gurnard, butterfly gurnard, Eastern spiny gurnard or Southern spiny gurnard. is a species of demersal marine ray-finned fish belonging to the family Triglidae, the gurnards and sea robins. This species is endemic to Australia.
