The northern lampfish (Stenobrachius leucopsarus), also known as smallfin lanternfish, [1] is a small oceanic fish in the family Myctophidae. First described by husband and wife ichthyologists Carl H. and Rosa Smith Eigenmann in 1890, [2] it is named for the numerous small round photophores that line the ventral surface of its head and body.
A blunt-nosed, relatively large-mouthed fish with small teeth and large eyes, [3] it is gray to dark greenish blue on its dorsal surface and paler ventrally, with black on its fins and operculum. [2] Its large scales rub off easily. [3] Adults can reach 13 centimetres (5 in) in length [3] and live as long as 8 years. [2]
Found in the Pacific Ocean from Japan and Baja California to the Bering Sea, [3] it is the most common species of lanternfish in the northwestern Pacific, [4] and one of the most abundant larval fish in the California Current. [5] Like all lanternfish, this is a deep sea species; it spends the day in the ocean's deeper bathypelagic and mesopelagic zones and ascends to or near the ocean's surface during the night. [3] [4] It is a cool-water fish. [6]
Like most fish, it is oviparous; [2] It feeds on plankton, [7] and is eaten by numerous predators, including fish such as salmon and tuna [3] and birds such as the red-legged kittiwake. [8]
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.
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout.
Lanternfish are small mesopelagic fish of the large family Myctophidae. One of two families in the order Myctophiformes, the Myctophidae are represented by 246 species in 33 genera, and are found in oceans worldwide. Lanternfishes are aptly named after their conspicuous use of bioluminescence. Their sister family, the Neoscopelidae, are much fewer in number but superficially very similar; at least one neoscopelid shares the common name "lanternfish": the large-scaled lantern fish, Neoscopelus macrolepidotus.
Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs.
Thyrsites atun, known as the snoek in South Africa and as the barracouta in Australasia, is a long, thin species of snake mackerel found in the seas of the Southern Hemisphere, and a popular food fish in South Africa, particularly along the west and southwest coast. Despite its Australasian name, it is not closely related to the barracuda.
The North Pacific hake, Pacific hake, Pacific whiting, or jack salmon is a ray-finned fish in the genus Merluccius, found in the northeast Pacific Ocean from northern Vancouver Island to the northern part of the Gulf of California. It is a silver-gray fish with black speckling, growing to a length of 90 cm (3 ft). It is a migratory offshore fish and undergoes a daily vertical migration from the surface to the seabed at depths down to about 1,000 m (3,300 ft). It is the object of an important commercial fishery off the West Coast of the United States, and annual quotas are used to prevent overfishing.
Symbolophorus is a genus of lanternfishes. It feeds on various small forms of sea life, in particular fish. Some species in this genus are known to exhibit the Stylophthalmine trait in their larval form
Lampanyctus is a genus of lanternfishes.
Ceratoscopelus is a genus of lanternfish.
Diaphus is a genus of lanternfishes. It is the most species-rich lanternfish genus.
The Neoscopelidae are a small family of deep-sea fish closely related to the lanternfish. They are found in tropical and subtropical marine waters worldwide.
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.
Ogcocephalus is a genus of marine ray-finned fishes belonging to the family Ogcocephalidae, the deep sea batfishes. The species in this genus are found in the Eastern Pacific Ocean and Western Atlantic Ocean, with most species in the eastern Atlantic Ocean where they live at shallower depths than the other ogcocephalid genera.
Myctophum affine, the metallic lanternfish, is a species of lanternfish native to the Atlantic Ocean. Myctophum affine grows to a length of 7.9 centimetres (3.1 in) SL.
Bolinichthys is a genus of lanternfishes.
Notoscopelus is a genus of lanternfishes.
Stenobrachius is a genus of lanternfishes.
Lampadena speculigera is a species of lanternfish in the subfamily Lampanyctinae. It is a mesopelagic fish that is found in the Atlantic, Indian, and Pacific Oceans. Its vernacular name is mirror lanternfish.
The headlight fish is a species of lanternfish in the family Myctophidae. It is also sometimes referred to as the headlight lanternfish, or even the lanternfish, though it is not the only species to be called this.
Jordaniidae is a small family of marine ray-finned fishes belonging to the order Scorpaeniformes. These fishes are found in the eastern North Pacific Ocean.
