Rhinogobiops
''Rhinogobiops'' is a genus of true gobies in the family Gobiidae. It is monotypic, being represented by the single species, ''Rhinogobiops nicholsii'', also known as the blackeye goby, bluespot goby, and crested goby. They are common inhabitants of coral reefs and rocky habitats along the eastern Pacific Ocean coasts of Mexico, the United States, and Canada, although they are hardly noticed, as they often rest motionless near their shelters. Blackeye gobies range in color from creamy white to a mottled dark purple-brown, but can easily be recognized by the distinctive black spot on their first dorsal fins and an iridescent blue spot beneath their eyes. They are capable of rapidly changing their color in response to social situations or threats. They are also protogynous hermaphrodites, starting out in life as females. They are highly territorial and each male usually maintains a harem of two to eight females. Taxonomy The blackeye goby is the only species recognised in the ge ...

Gobiinae
True gobies were a subfamily, the Gobiinae, of the goby family Gobiidae, although the 5th edition of the '' Fishes of the World'' does not subdivide the Gobiidae into subfamilies. They are found in all oceans and a few rivers and lakes, but most live in warm waters. Altogether, the Gobiinae unite about 1149 described species in 160 genera, and new ones are still being discovered in numbers. Description and ecology They are usually mid-sized to small ray-finned fishes; some are very colorful, while others are cryptic. Most true gobies are less than 10 cm (4 in) long when fully grown. The largest species ''Glossogobius giuris'' can reach up to 50 cm (20 in); the smallest known species as of 2010, '' Trimmatom nanus'', is just about 1 cm in length when fully grown, making it one of the smallest vertebrates. In many true gobies, the pelvic fins have grown together into a suction cup they can use to hold on to substrate. Most have two dorsal fins, the fir ...

Valid Name (zoology)
In zoological nomenclature, the valid name of a taxon is the sole correct scientific name. The valid name should be used for that taxon, instead of any other name that may currently be being used, or may previously have been used. A name is valid when, and only when, it is in harmony with all the relevant rules listed in the International Code of Zoological Nomenclature (ICZN). A valid name is the correct zoological name of a taxon. In contrast, a name which violates the rules of the ICZN is known as an invalid name. An invalid name is not considered to be the correct scientific name for a taxon. There are numerous different kinds of invalid names. Subjectively invalid names Subjectively invalid names are names that have been rendered invalid by individual scientific judgement or opinion. Taxonomists may differ in their opinion, and names considered invalid by one researcher may be considered valid by another; thus these are still potentially valid names. They include: :*J ...

Lophogobius Cyprinoides
''Lophogobius cyprinoides'', commonly known as the crested goby, is a small fish that is widespread throughout the western Atlantic Ocean. Description The crested goby is a small but stout fish, reaching a maximum length of . Its body appears compressed and a crest extends back from the middle of its eyes. They have six dorsal spines with the fourth spine being the longest, and 16–20 pectoral fin rays which reach beyond the start of the anal fin in adults. The tail is wide and round. Both sexes have reddish-brown to olive mottling along their head and bodies, but those of the males are more extensive and darker in color. The females cheeks are covered with pale spots, also with several pale lines behind eye, while males have black and orange spots on the first dorsal fin, which change to black and violet during breeding. Distribution and habitat This widespread species occurs throughout the western Atlantic Ocean, from South Florida and Bermuda, throughout the Caribbean, and ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Scale (fish)
In most biological nomenclature, a scale ( grc, λεπίς, lepís; la, squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopteran (butterfly and moth) species, scales are plates on the surface of the insect wing, and provide coloration. Scales are quite common and have evolved multiple times through convergent evolution, with varying structure and function. Scales are generally classified as part of an organism's integumentary system. There are various types of scales according to shape and to class of animal.

Fish Anatomy
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coryphopterus
''Coryphopterus'' is a genus of gobies primarily found in the western Atlantic Ocean, although some species are found in the Indian and/or Pacific oceans. Species There are currently 14 recognized species in this genus: * '' Coryphopterus alloides'' J. E. Böhlke & C. R. Robins, 1960 (Barfin goby) * '' Coryphopterus curasub'' C. C. Baldwin & D. R.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...
