Moontail Bullseye
''Priacanthus hamrur'', the lunar-tailed bigeye, goggle eye, or moontail bullseye, is a species of marine fishes belonging to the family Priacanthidae. Distribution This species is uncommon but widespread in the Indo-Pacific, from the Red Sea and southern Africa to French Polynesia, southern Japan, and Australia. It has been reported also from Easter Island. Two records have been reported from the Mediterranean Sea off Tunisia and Turkey respectively. Habitat ''Priacanthus hamrur'' is a reef-associated species, living in tropical marine waters on outer reef slopes and rocky areas and in lagoons at depths of 8 to 250 meters, but most commonly from 30 to 50 m. Description At sexual maturity the size of ''Priacanthus hamrur'' reaches in males, in females, but males can reach a maximum length of 45 cm. The body of the Crescent-tail Bigeye is relatively deep, strongly compressed laterally. The eyes are very large and red (even in case of silver livery). The mouth is oblique ...

Peter Forsskål
Peter Forsskål, sometimes spelled Pehr Forsskål, Peter Forskaol, Petrus Forskål or Pehr Forsskåhl (11 January 1732 – 11 July 1763) was a Swedish-speaking Finnish explorer, orientalist, naturalist, and an apostle of Carl Linnaeus. Early life Forsskål was born in Helsinki, now in Finland but then a part of Sweden, where his father, Finnish priest , was serving as a Lutheran clergyman, but the family migrated to Sweden in 1741 when the father was appointed to the parish of Tegelsmora in Uppland and the archdiocese of Uppsala. As was common at the time, he enrolled at Uppsala University at a young age in 1742, but returned home for some time and, after studies on his own, rematriculated in Uppsala in 1751, where he completed a theological degree the same year. Linnaeus's disciple In Uppsala Forsskål was one of the students of Linnaeus, but apparently also studied with the orientalist Carl Aurivillius, whose contacts with the Göttingen orientalist Johann David Michae ...

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 ...

Heteropriacanthus Cruentatus
''Heteropriacanthus'', the glasseyes or glass bigeyes, are a genus of the bigeye family found in all tropical seas around the world. It occasionally makes its way into the aquarium trade. It grows to a size of in total length. The glasseyes has been classified in a single species, ''Heteropriacanthus cruentatus'', but recent morphological and genetic analysis indicates that glasseyes may be better divided into three species: ''Heteropriacanthus cruentatus'' (Atlantic Ocean and southwest Indian Ocean), ''H. fulgens'' (northeastern Atlantic), and ''H. carolinus'' (Indo-Pacific The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the ...). H.cruentatus can differentiated from the rest of its genus by looking at its caudal and anal fin in which is distinct in colour. References External lin ...

Priacanthus Blochii
''Priacanthus blochii'', the paeony bulleye, is a species of marine ray finned fish, a bigeye in the family Priacanthidae. Other common names for this species include Bloch's bigeye, blotched bigeye, glass-eye bigeye, shortfin bigeye, silver big-eye and goggle eye. Description ''Priacanthus blochii'' has a red body and is commonly in length. The lateral line has a line of approximately 15 dark spots. Both the pelvic and median fins are a dusky red colour. At the base of the first 3 pelvic rays, a black spot is present. It can change colour as its mood changes. Distribution ''Priacanthus blochii'' occurs in the waters of southern Africa to French Polynesia. It is found as far south as Australia and north to the southern waters of Japan. It has also been recorded around Easter Island and as well as in the Red Sea. Habitat ''Priacanthus blochii'' is found at depths of 8 to 250 metres in caves or under ledges and inhabits lagoons and seaward reefs. It is frequentlyfound in silty ar ...

Eye Of Priacanthus Hamrur
Eyes are organs of the visual system. They provide living organisms with vision, the ability to receive and process visual detail, as well as enabling several photo response functions that are independent of vision. Eyes detect light and convert it into electro-chemical impulses in neurons (neurones). In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods. The most simple eyes, pit eyes, are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
