Acantholiparis Caecus
''Acantholiparis caecus'' is one of the two snailfishes within the genus ''Acantholiparis'', along with '' A. opercularis'', the spiny snailfish. Its generic name comes from the Greek for thorny (akantha) and fat (liparis); its specific name comes from the Latin word for blind. Biology ''Acantholiparis caecus'' grows to a maximum length of 5.7 cm, which is slightly less than what is known of its closest relative, the spiny snailfish. Females are larger than males, whose maximum size is 3.9 cm. Habitat ''Acantholiparis caecus'' is known from depths stretching from 1,300m to 2,122m, in the bathyal or midnight zone of the ocean. Unlike the spiny snailfish, it is pelagic, living above the ocean floor rather than upon it as the demersal spiny snailfish does. Distribution ''Acantholiparis caecus'' is a more southern fish than ''A. opercularis'', inhabiting an area off the coast of Oregon and northern California California is a U.S. state, state in the West ...

Snailfishes
The Liparidae, commonly known as snailfish or sea snails, are a family of marine scorpaeniform fishes. Widely distributed from the Arctic to Antarctic Oceans, including the oceans in between, the snailfish family contains more than 30 genera and about 410 described species, but there are also many undescribed species. Snailfish species can be found in depths ranging from shallow surface waters to greater than 8,000 meters, and species of the Liparid family have been found in seven ocean trenches. They are closely related to the sculpins (family Cottidae) and lumpfish (family Cyclopteridae). In the past, snailfish were sometimes included within the latter family. Description The snailfish family is poorly studied and few specifics are known. Their elongated, tadpole-like bodies are similar in profile to the rattails. Their heads are large (compared to their size) with small eyes; their bodies are slender to deep, tapering to very small tails. The extensive dorsal and anal f ...

Acantholiparis Opercularis
''Acantholiparis opercularis'', or the spiny snailfish, is one of two species within the snailfish genus ''Acantholiparis''. The generic name comes from the Greek ''akantha'' meaning "thorn" and ''liparis'' meaning "fat". The specific name comes from the Latin ''opercularis'', meaning covered (as in a lid). Size The spiny snailfish is a small fish, with a length up to 7 cm. Habitat The spiny snailfish is a deep-water fish, known from depths between 227 m and 3600 m. It is a demersal fish, living just above the seabed. Range ''Acantholiparis opercularis'' lives generally near the coast, over a wide range stretching as a crescent from Kamchatka to Alaska and as far south as the coast of Oregon Oregon () is a state in the Pacific Northwest region of the Western United States.

Bathyal Zone
The bathypelagic zone or bathyal zone (from Greek βαθύς (bathýs), deep) is the part of the open ocean that extends from a depth of below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below. The bathypelagic is known as the midnight zone because of the lack of sunlight; this feature does not allow for photosynthesis-driven primary production, preventing growth of phytoplankton or aquatic plants. Although larger by volume than the photic zone, our knowledge of the bathypelagic zone remains limited by our ability to explore the deep ocean. Physical characteristics The bathypelagic zone is characterized by a nearly constant temperature of approximately and a salinity range of 33-35 g/kg. This region has little to no light, because sunlight does not reach this deep in the ocean and bioluminescence is limited. The hydrostatic pressure in this zone ranges 100-400 atmospheres (atm), due to the increase of 1 atm for every 10 m depth. It is ...

Spiny Snailfish
''Acantholiparis opercularis'', or the spiny snailfish, is one of two species within the snailfish genus ''Acantholiparis''.

Size The spiny snailfish is a small fish, with a length up to 7 cm. Habitat The spiny snailfish is a deep-water fish, known from depths between 227 m and 3600 m. It is a demersal fish, living just above the seabed.

Pelagic
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...

Demersal
The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. The demersal zone is just above the benthic zone and forms a layer of the larger profundal zone. Being just above the ocean floor, the demersal zone is variable in depth and can be part of the photic zone where light can penetrate, and photosynthetic organisms grow, or the aphotic zone, which begins between depths of roughly and extends to the ocean depths, where no light penetrates. Fish The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (''Gadus morhua'') is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (''Clupea harengus'') is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel. Two types of fish inhabit the demersal zon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon
Oregon () is a state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. Spanish ships – 250 in as many years – would typically not land before reaching Cape M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Of The Pacific Ocean
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 ...
