The shortbill spearfish (Tetrapturus angustirostris), sometimes called the short-nosed spearfish, is a species of marlin native to the Indian and Pacific Oceans, with occasional records from the Atlantic Ocean. This species occurs in open waters not far from the surface. This species can reach a length of 230 cm (91 in), though most do not exceed 190 cm (75 in). The maximum recorded weight for this species is 52 kg (115 lb). It is of minor importance to commercial fisheries and is also a game fish. [2] Short bill spearfish are characterized by a slim frame with a blue body that is silver underneath. Shortbill also possess a very short bill extending from their upper jaw.
Spearfishing is fishing using handheld elongated, sharp-pointed tools such as a spear, gig, or harpoon, to impale the fish in the body. It was one of the earliest fishing techniques used by mankind, and has been deployed in artisanal fishing throughout the world for millennia. Early civilizations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks.
The Caspian tern is a species of tern, with a subcosmopolitan but scattered distribution. Despite its extensive range, it is monotypic of its genus, and has no accepted subspecies. The genus name is from Ancient Greek hudros, "water", and Latin progne, "swallow". The specific caspia is from Latin and, like the English name, refers to the Caspian Sea.
The shortfin mako shark, also known as the shortfin mako, blue pointer, or bonito shark, is a large mackerel shark. It is commonly referred to as the mako shark, as is the longfin mako shark. The fastest known shark species, able to reach speeds of 74 km/h (46 mph) in bursts, the shortfin mako can attain a size of 4 m (13 ft) in length and weigh 570 kg (1,260 lb). The species is classified as Endangered by the IUCN.

The white marlin, also known as Atlantic white marlin, marlin, skilligalee, is a species of billfish that lives in the epipelagic zone of the tropical and subtropical Atlantic Ocean. They are found between the latitudes of 45° N and 45° S in waters deeper than 100 m. Even though white marlin are found in bodies of water that are deeper than 100 m they tend to stay near the surface. White marlin have been found near banks, shoals, and canyons, but they are not limited to those locations. They prefer warm surface temperatures greater than 22 °C.
The billfish are a group of saltwater predatory fish characterised by prominent pointed bills (rostra), and by their large size; some are longer than 4 m (13 ft). Extant billfish include sailfish and marlin, which make up the family Istiophoridae; and swordfish, sole member of the family Xiphiidae. They are often apex predators which feed on a wide variety of smaller fish, crustaceans and cephalopods. These two families are sometimes classified as belonging to the order Istiophoriformes, a group which originated around 71 million years ago in the Late Cretaceous, with the two families diverging around 15 million years ago in the Late Miocene. However, they are also classified as being closely related to the mackerels and tuna within the suborder Scombroidei of the order Perciformes. However, the 5th edition of the Fishes of the World does recognise the Istiophoriformes as a valid order, albeit including the Sphyraenidae, the barracudas.
The black marlin is a species of marlin found in tropical and subtropical areas of the Indian and Pacific Oceans approximately between 40 degrees North and 45 degrees South, while in some instances venturing into more temperate waters. Reaching lengths of over 4.5 m (15 ft), It is one of the largest marlins and also one of the largest bony fish. Marlin are among the fastest fish, but speeds may be exaggerated in popular media, such as reports of 132 km/h (82 mph). A 2016 study estimated maximum swimming speeds from muscle contraction times, which in turn limit the tail-beat frequency; the study suggested a theoretical upper limit for the black marlin's burst speed of 36 kilometres per hour (22 mph). Black marlin are fished commercially and are also a highly prized game fish. Black marlins were known to drag ancient Maldivian fishing boats for very long distances until the marlins tired; it would take many hours for the fishermen to row or sail back home. Due to the common misidentification of large billfish such as the black marlin, as well as its highly migratory habits and the lack of research into the species, much about populations are unknown. The species was first known as Tetrapturus indicus and later was reclassified as Makaira indica before taking on its current scientific name. One of the earliest scientific records of black marlin is its description by French zoologist Georges Cuvier in 1832.
The striped marlin is a species of marlin found globally in tropical to temperate oceans not far from the surface. It is a desirable commercial and game fish, although conservation measures are in place to restrict its commercial landings. An epipelagic predator, it hunts during the day in the top 100 metres (330 ft) or so of the water column, often near the surface. One of its chief prey is sardines.
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).
The black flounder, also known by the Māori language name mohoao, is a species of flatfish in the family Rhombosoleidae, found around New Zealand in shallow enclosed waters and coastal freshwater lakes. Its adult length ranges from 20 to 45 cm.
The black ruff is a medusafish, the only member of the genus Centrolophus. It is a pelagic fish found in all tropical and temperate oceans at depths of 0 to 1,000 m. Its length is typically up to 60 cm (24 in), but it may reach 150 cm (60 in). Other common names include rudderfish and blackfish.
The veiled anglemouth, Cyclothone microdon, is a bristlemouth of the family Gonostomatidae, abundant in all the world's oceans at depths of 300 – 2,500 meters. Its length is 10–15 cm (4–8 in) though the largest known specimen is 7.6 cm (3 in). It gets its name from its circular mouth, filled with small teeth: the name “cyclothone” means in a circle or around and “microdon” means small teeth. The International Union for Conservation of Nature (IUCN) has assessed the veiled anglemouth is of Least Concern due to its abundance in most oceans and the little effect human impact has on its population growth. Some of the veiled anglemouth's physical features include a brown to black body with a radiating, or expansive, bioluminescent pigment over its head and fins.
The crested bellowsfish or crested bellowfish, Notopogon lilliei, is a species of fish from the family Macroramphosidae. It is a demersal species which occurs over the continental shelf at depths of 80 to 600 m. They grow to lengths of up to 27 cm (11 in).
The elegant wrasse, Anampses elegans, is a species of wrasse native to the Pacific Ocean from Australia and New Zealand eastward to Easter Island. This species prefers lagoons and can also be found on coastal reefs at depths from 2 to 35 m. This species can reach a length of 29 cm (11 in). It can be found in the aquarium trade.
The spearfish remora is a species of remora with a worldwide distribution in tropical and subtropical seas. Remoras attach themselves to other fish with a sucker on the head and this fish is almost exclusively found living on billfishes or swordfishes, and sometimes on sharks.
The bulbous dreamer, or cosmoplitan dreamer, is a species of marine ray-finned fish belonging to the family Oneirodidae, the dreamers, a family of deep-sea anglerfishes. This fish has a circumglobal distribution in tropical and temperate oceans.
The roundscale spearfish is an Istiophoridae species of marlin living in the epipelagic zone of the Atlantic Ocean. It has long been misidentified as white marlin but can be differentiated thanks to their scale shapes that gives its name. Not much is known about this species. It could reach a length of 160 cm and 21,5 kg and has no conservation status yet due to a lack of data.
Tetrapturus is a genus of marlins commonly called spearfish, found in tropical and subtropical oceans throughout the world. Some are popular sport fish in big-game fishing.
The longbill spearfish is a species of marlin native to the Atlantic Ocean where it is found above the thermocline in open waters between 40°N and 35°S. This species can reach a length of 254 centimetres (100 in) FL and the maximum weight recorded is 58 kilograms (128 lb). It feeds on pelagic fishes such as needlefish, tuna, and jack, as well as squids. They spawn once a year. The specific name honours the Florida game fisherman and taxidermist Albert Pflueger Sr, who died in 1962.
The Mediterranean spearfish is a species of marlin native to the Mediterranean Sea where it is particularly common around Italy, although there is a probable record of one caught off Madeira. It is an open-water fish, being found within 200 metres (660 ft) of the surface. This species can reach a length of 240 centimetres (94 in) TL. The heaviest recorded specimen weighed in at 70 kilograms (150 lb) This species is of minor importance to commercial fisheries.
