Linophryne Macrodon
''Linophryne macrodon'' is a species of bearded seadevils in the family Linophrynidae, that live in waters 300 to 1000 m (980 to 3280 ft) deep in the Eastern Central Pacific Ocean. Description Females grow up to 9.1 cm in length, and have a single distal branched filament, that is half the diameter of the bulb. It has three branches along each side of the bulb, that can be 3 times the diameter of the bulb, and have subdermal pigment on the caudal peduncle. Males are smaller, at only 2.2 cm in length, and have pointed sphenotic spines. The eggs of ''L. macrodon'' are only 1 mm in diameter. Specimens All the specimens of ''L. macrodon'' have been caught from non-closing nets, from depths to 1000 m (3280 ft), but one that was 44 mm was taken at only 300 m (980 ft) deep from a bottom haul in the mesopelagic zone The mesopelagic zone (Greek μέσον, middle), also known as the middle pelagic or twilight zone, is the part of the pelagic zone that lies betwee ...

Leftvent
Leftvents are small, deep-sea lophiiform fish comprising the family Linophrynidae distributed throughout tropical to subtropical waters of all oceans. The name of the type genus '' Linophryne'' has been translated from the Greek to mean "toad that fishes with a net", an allusion to the fishes' impressive use of mimicry in luring prey. One of several families of anglerfishes, the Linophrynidae are not well studied, and only one species is given a common name: the netdevil, ''Borophryne apogon''. For this reason, the name "netdevil" can sometimes refer to any linophrynid. Description With roughly spherical to slightly elongated, gelatinous, and scaleless bodies and large triangular heads, leftvents possess a body plan typical of deep-sea anglerfish. In females only, long, sharp fang-like teeth line the jaws of a cavernous maw. An illicium (a modified dorsal spine; the "fishing rod") — and an esca (a bulbous, bioluminescent "fishing lure") are present, also in females only. The ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Pigment
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide. Estimated at around US$14.86 billion in 2018 and will rise at over 4.9% CAGR from 2019 to 2026. The global demand for pigments was roughly US$20.5 billion in 2009. According to an April 2018 report by '' Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year.

Mesopelagic Zone
The mesopelagic zone (Greek μέσον, middle), also known as the middle pelagic or twilight zone, is the part of the pelagic zone that lies between the photic epipelagic and the aphotic bathypelagic zones. It is defined by light, and begins at the depth where only 1% of incident light reaches and ends where there is no light; the depths of this zone are between approximately 200 to 1,000 meters (~656 to 3,280 feet) below the ocean surface. The mesopelagic zone occupies about 60% of the planet's surface and about 20% of the ocean's volume, amounting to a large part of the total biosphere. It hosts a diverse biological community that includes bristlemouths, blobfish, bioluminescent jellyfish, giant squid, and a myriad of other unique organisms adapted to live in a low-light environment. It has long captivated the imagination of scientists, artists and writers; deep sea creatures are prominent in popular culture. Physical conditions The mesopelagic zone includes the regi ...

Fish Described In 1925
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...
