Symphurus
''Symphurus'' is a genus of fish in the family Cynoglossidae found in the Atlantic, Indian and Pacific Ocean. Most species mainly occur in relatively shallow water, including estuaries.

Symphurus Thermophilus
''Symphurus thermophilus'' is a species of tonguefish notable for being the only flatfish known to be an obligate inhabitant of hydrothermal vents. It is known from several widely dispersed locations in the western Pacific Ocean and occurs in great numbers. They are tolerant of harsh conditions and are often found in close association with elemental sulfur, including molten sulfur pools that exceed 180 °C in temperature. As they are not significantly different in appearance and feeding habits from other tonguefishes, they are thought to be relatively recent colonizers of vent ecosystems. These fish were first observed in nature in 1988, and were provisionally assigned to the species ''Symphurus orientalis'' before being recognized as a new species. The species name ''thermophilus'' is from the Greek ''thermos'' meaning "heat" and ''philos'' meaning "lover", referring to its association with hydrothermal vents. Distribution and habitat This species has a wide, disjunct distr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatfish
A flatfish is a member of the Ray-finned fish, ray-finned demersal fish order (biology), order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. Many important food fish are in this order, including the flounders, sole (fish), soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Over 800 described species are placed into 16 families. Broadly, the flatfishes are divided into two suborders, Psettodoidei and Pleuronectoidei, with > 99% of the species diversity found within the Pleuronectoidei. The largest families are Soleidae, Bothidae and Tonguefish, Cynoglossidae with more than 150 species each. There also exist two monotypic families (P ...

Hydrothermal Vent
A hydrothermal vent is a fissure on the seabed from which geothermally heated water discharges. They are commonly found near volcanically active places, areas where tectonic plates are moving apart at mid-ocean ridges, ocean basins, and hotspots. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Under the sea, they may form features called black smokers or white smokers. Relative to the majority of the deep sea, the areas around hydrothermal vents are biologically more productive, often hosting complex communities fueled by the chemicals dissolved in the vent fluids. Chemosynthetic bacteria and Archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp. Active hydrothermal vents are thought to exist on Jupiter's moon Europa an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Adult
An adult is a human or other animal that has reached full growth. In human context, the term ''adult'' has meanings associated with social and legal concepts. In contrast to a " minor", a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and responsible. They may also be regarded as a "major". The typical age of attaining legal adulthood is 18, although definition may vary by legal rights, country, and psychological development. Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; a person may be biologically an adult, and have adult behavior, but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may define an adult character. In different cultures there are events that relate passing from being a child to becomin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cranium
The skull is a bone protective cavity for the brain. The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone. However two parts are more prominent: the cranium and the mandible. In humans, these two parts are the neurocranium and the viscerocranium ( facial skeleton) that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalisation—housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localisation of the direction and distance of sounds. In some animals, such as horned ungulates (mammals with hooves), the skull also has a defensive function by providing the mount (on the fron ...

John Ernest Randall
John Ernest "Jack" Randall (May 22, 1924 – April 26, 2020) was an American ichthyologist and a leading authority on coral reef fishes. Randall described over 800 species and authored 11 books and over 900 scientific papers and popular articles. He spent most of his career working in Hawaii. He died in April 2020 at the age of 95. Career John Ernest Randall was born in Los Angeles, California in May 1924, to John and Mildred (McKibben) Randall. In high school he acquired a love of marine fish after a visit to the tide pools of Palos Verdes and, after serving stateside in the Medical Corps of the U.S. Army during the post- D-Day years of WWII,John Randall bio, The Academy of Underwater Arts & Sciences. (http://www.auas-nogi.org/bio_randall_john.html) received his BA degree from the University of California, Los Angeles in 1950. In 1955 he earned his Ph.D in ichthyology from the University of Hawaii. After spending two years as a research associate at the Bishop Museum in Honol ...

Charles Richard Robins
Charles Richard Robins (November 25, 1928 – November 12, 2020) was an American academic, environmentalist and ichthyologist. Early life and university Robins was born on November 25, 1928 in Harrisburg, Pennsylvania, to Helen Ayers Robins and Claude Revere Robins, a jewellery wholesaler (and eventual Mayor of Harrisburg), who was their third and final child. As a child Robins developed an interest in natural history, particularly birds. This early ornithological interest was apparently encouraged by George M. Sutton, the Pennsylvania State Ornithologist. Robins enjoyed the writings of the celebrated ornithologist Arthur Augustus Allen of Cornell University in Ithaca, New York. Robins wanted to study under Allen, so he went to Cornell in 1946, However, by that time the biology department had begun to move from concentrating on ornithology to ichthyology led by Edward C. Raney. Nevertheless, Robins finished his Ph.D. thesis in 1955, revising the eastern North American sculpins w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
