Dasyscopelus asper, previously Myctophum asperum, [2] common name the prickly lanternfish, is a species of deep sea fish in the family Myctophidae, the "lanternfish". [1] [2] [3]
This species has large eyes [4] and grows to a maximum total length of approximately 8.5 cm (3.3 in). [3]
Dasyscopelus asper is found in the following regions: [3]
Larvae have also been found in the Taiwan Strait. [3]
This species is found at depths of between 425 and 750 metres during the day. [3] At night it can ascend to depths of 125 metres to feed on plankton. [4]
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water movements.
The Benguela Current is the broad, northward flowing ocean current that forms the eastern portion of the South Atlantic Ocean gyre. The current extends from roughly Cape Point in the south, to the position of the Angola-Benguela front in the north, at around 16°S. The current is driven by the prevailing south easterly trade winds. Inshore of the Benguela Current proper, the south easterly winds drive coastal upwelling, forming the Benguela Upwelling System. The cold, nutrient rich waters that upwell from around 200–300 m (656–984 ft) depth in turn fuel high rates of phytoplankton growth, and sustain the productive Benguela ecosystem.
The Kuroshio Current, also known as the Black Current or Japan Current is a north-flowing, warm ocean current on the west side of the North Pacific Ocean basin. It was named for the deep blue appearance of its waters. Similar to the Gulf Stream in the North Atlantic, the Kuroshio is a powerful western boundary current that transports warm equatorial water poleward and forms the western limb of the North Pacific Subtropical Gyre. Off the East Coast of Japan, it merges with the Oyashio Current to form the North Pacific Current.
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.
The Agulhas Bank is a broad, shallow part of the southern African continental shelf which extends up to 250 km (160 mi) south of Cape Agulhas before falling steeply to the abyssal plain.
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.
Warming's lantern fish, Ceratoscopelus warmingii, is a lanternfish of the family Myctophidae, found circumglobally in both hemispheres, at depths of between 700 and 1,500 m during the day and between 20 and 200 m at night. Its length is about 8 cm (3.15 in).
Sepia australis, the southern cuttlefish, is a species of cuttlefish which is found in the eastern South Atlantic Ocean and the western Indian Ocean off the coasts of Southern Africa, possibly extending into the waters off East Africa.
Myctophum nitidulum, common name pearly lanternfish, is a species of deep sea fish in the family Myctophidae, the "lanternfish".
Acropora abrotanoides is a species of acroporid coral found in Indo-Pacific waters from the Red Sea and the Gulf of Aden east to the East China Sea, Japan, the central Pacific Ocean and Australia. It is found in shallow coral reefs that are exposed to the action of strong waves, at depths up to 15 m. It is vulnerable to coral bleaching, disease and crown-of-thorns starfish. It is resistant to predation as it has well-developed radial corallite lips.
Myctophum punctatum is a species of mesopelagic fish in the family Myctophidae. Its common name is spotted lanternfish, sometimes spelled spotted lanterfish. It is found in the Northern Atlantic and in the Mediterranean at depths down to 1000m. It is one of the dominant species in midwater assemblages near the Mid-Atlantic Ridge.
Notoscopelus resplendens, commonly known as the patchwork lampfish or patchwork lanternfish, is a species of lanternfish in the family Myctophidae. It is found in the eastern and western Atlantic Ocean, the Indian Ocean and parts of the Pacific Ocean. It spends the daylight hours in deep water, rising at night to near the surface. This fish was first described by the Scottish naturalist and arctic explorer John Richardson in 1845.
Notoscopelus caudispinosus is a species of lanternfish in the family Myctophidae. It is found in the eastern and western Atlantic Ocean, the Indian Ocean and parts of the Pacific Ocean. It spends the day below 1,000 m (3,300 ft), rising towards the surface to feed at night.
Dasyscopelus obtusirostris, the bluntsnout lanternfish, is a species of lanternfish. It occurs in the Atlantic, Indian, and Pacific Oceans.
Gonichthys cocco, often called the Cocco's lanternfish, is a species of oceanodromous lanternfish.
The longfin lanternfish is a species of oceanodromous lanternfish that is oviparous, and a host of Sarcotretes scopeli.
Kyphosus bigibbus, the brown chub, grey drummer, darkfin drummer, insular rudderfish, grey chub, grey sea chub, southern drummer or topsail drummer is a species of marine ray-finned fish, a sea chub from the family Kyphosidae. It is a herbivorous species which is found in subtropical and tropical seas worldwide.
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.
Diaphus jenseni, also known as Jensen's lanternfish, is a species of lanternfish found in the Indo-Pacific, the south-eastern Atlantic Ocean and the South China Sea.
