A tuna is a saltwater fish that belongs to the tribe Thunnini, a subgrouping of the Scombridae (mackerel) family. The Thunnini comprise 15 species across five genera, the sizes of which vary greatly, ranging from the bullet tuna up to the Atlantic bluefin tuna, which averages 2 m (6.6 ft) and is believed to live up to 50 years.
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.
Herring are forage fish, mostly belonging to the family of Clupeidae.
Wobbegong is the common name given to the 12 species of carpet sharks in the family Orectolobidae. They are found in shallow temperate and tropical waters of the western Pacific Ocean and eastern Indian Ocean, chiefly around Australia and Indonesia, although one species occurs as far north as Japan. The word wobbegong is believed to come from an Australian Aboriginal language, meaning "shaggy beard", referring to the growths around the mouth of the shark of the western Pacific.
The Ganges shark is a critically endangered species of requiem shark found in the Ganges River and the Brahmaputra River of India and Bangladesh. It is often confused with the more common bull shark, which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. The genus is currently considered to contain three recent species; genetic evidence has shown that both the Borneo river shark and Irrawaddy river shark should be regarded as synonyms of the Ganges shark, expanding the range of the species to Pakistan, Myanmar, Borneo, and Java. While the other members of the genus Glyphis occur in coastal marine waters as well as rivers, the Ganges shark is found only in fresh water, making it the world's only exclusively freshwater shark. The species remains poorly known and very rare.
Sir John Murray was a pioneering Canadian-born Scottish oceanographer, marine biologist and limnologist. He is considered to be the father of modern oceanography.
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 Pacific bluefin tuna is a predatory species of tuna found widely in the northern Pacific Ocean, but it is migratory and also recorded as a visitor to the south Pacific.
The Christmas Island pipistrelle is an extinct species of vesper bat that was found only on Christmas Island, Australia.The last individual bat seen in August 2009 with no further sightings despite intensive efforts to locate it.
Ipnops is a genus of deep-sea fish in the family Ipnopidae, which also includes the better-known tripodfish. Ipnops are small, slender fish that live close to the ocean floor in the bathyal and abyssal zones. The genus is notable for its unusual eyes.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 19 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water.
Paraheminodus is a genus of marine ray-finned fish belonging to the family Peristediidae, the armoured gurnards or armored searobins. These fishes are found in the western Pacific Ocean.
Melanocetus murrayi, commonly known as Murray's abyssal anglerfish, is a deep sea anglerfish in the family Melanocetidae, found in tropical to temperate parts of the world's oceans at depths down to over 2,000 m (6,600 ft). Its length is up to 13.5 cm (5 in) for females and up to 2.8 cm (1.1 in) for males.
Cirrothauma magna is a species of deep-sea cirrate octopus that has been found in the Indian, Atlantic, and Pacific oceans. It is known from only 4 specimens. Their shells are somewhat saddle-shaped. C. magna is the sister taxon of Cirrothauma murrayi, but can be readily distinguished by having large and well developed eyes.
Cirrothauma murrayi, the blind cirrate octopus, is a nearly blind octopus whose eyes can sense light, but not form images. It has been found worldwide, usually 1,500 to 4,500 metres beneath the ocean's surface. Like other cirrates, it has an internal shell, muscular fins for swimming, and a web connecting the arms.
Triglops murrayi, the moustache sculpin, is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This fish is found in the North Atlantic Ocean.
The roughnose grenadier is a species of fish in the subfamily Macrourinae (rat-tails). The species is named for Sir John Murray.
Murray's smooth-head, also called Murray's slickhead, is a species of fish in the family Alepocephalidae.
