Dactyloscopidae
Sand stargazers are blennioids; perciform marine fish of the family Dactyloscopidae. Found in temperate to tropical waters of North and South America; some may also inhabit brackish environments. The giant sand stargazer (''Dactylagnus mundus'') is the largest at 15 cm in length; all other species are under 10 cm. These blennies are named well: sand stargazers have protruding eyes on the top of their heads, fixed in an upward gaze, and may be on stalks. Their large mouths are also upturned. The dorsal fin is long and may or may not be continuous, with seven to 23 spines; the pelvic fins are situated below the throat and possess one spine. The anal fin is equally long and flowing. The mouth is fringed, and like the upper edge of the operculum (the gill cover), this fringe is divided into finger-like structures. The body is greatly elongated, and coloration is generally drab. As their name would suggest, sand stargazers spend most of their time buried in sandy substrates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Storrs Olson
Storrs Lovejoy Olson (April 3, 1944 – January 20, 2021) was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii. His early higher education took place at Florida State University in 1966, where he obtained a B.A. in biology, and the University of Florida, where he received an M.S. in biology. Olson's doctoral studies took place at Johns Hopkins University, in what was then the School of Hygiene and Public Health. He was married to fellow paleornithologist Helen F. James. Early life and education Olson was born April 4, 1944, in Chicago, Illinois. His father was physical oceanographer Franklyn C.W. Olson. He was named after his maternal conservationist grandfather P.S. Lovejoy. Franklyn worked at the University of Ohio's Stone Laboratory on Gibral ...

Charles Eric Dawson
Charles Eric "Chuck" Dawson (December 6, 1922 – February 11, 1993) was a Canadian-American ecologist, ichthyologist, and taxonomist. He held expertise in gobies, flatfishes, and sand stargazers, and was considered "the ultimate authority" on pipefishes in the family Syngnathidae. Life Dawson was born in Vancouver, British Columbia, Canada, but would eventually spend much of his career at the University of Southern Mississippi's Gulf Coast Research Laboratory in Ocean Springs, Mississippi, where he worked early as an administrator, then researcher, and museum curator. Over his long career Dawson wrote 150 publications, on the majority of which he was the sole author. He recognized 52 Syngnathid genera and provided systematic reviews of most of them. His work culminated with his extensive review of all Indo-Pacific pipefishes. He died as a result of a branchioloalveolar carcinoma in combination with other long-term lung ailments. Dawson served in the Canadian Army during World ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Atlantic
The Tropical Atlantic realm is one of twelve marine realms that cover the world's coastal seas and continental shelves. The Tropical Atlantic covers both sides of the Atlantic. In the western Atlantic, it extends from Bermuda, southern Florida, and the southern Gulf of Mexico through the Caribbean and along South America's Atlantic coast to Cape Frio in Brazil's Rio de Janeiro state. In the Eastern Atlantic, it extends along the African coast from Cape Blanco in Mauritania to the Tigres Peninsula on the coast of Angola. It also includes the seas around St. Helena and Ascension islands. The Tropical Atlantic is bounded on the north and south by temperate ocean realms. The Temperate Northern Atlantic realm lies to the north on both the North American and African-European shores of the Atlantic. To the south, the ocean realms conform to the continental margins, not the ocean basins; the Temperate South America realm lies to the south along the South American coast, and th ...

Monotypic Marine Fish Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Endemic Fauna Of Brazil
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Brazil
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. ...

Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus '' Homo'' and within this genus to the species '' Homo sapiens''. '' Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...
