Grammatidae - Gramma Melacara
Grammatidae is a small family of ray-finned fishes which were formerly placed in the order Perciformes but are now regarded as being '' incertae sedis'' in the subseries Ovalentaria in the clade Percomorpha. They are commonly known as basslets. They are marine fish found in the tropical western Atlantic Ocean. They are characterized in part by a broken or absent lateral line. The largest species reach around 10 centimeters in maximum length. Some basslets are colorful and are kept in marine aquaria. There are two genera: * '' Gramma'' * ''Lipogramma'' A number of other species may be called "basslets", in particular members of Serranidae, where they may be called "fairy basslets".

Royal Gramma
The royal gramma (''Gramma loreto''), also known as the fairy basslet, is a species of fish in the family Grammatidae native to reef environments of the tropical western Atlantic Ocean. They are commonly kept in aquariums. Appearance The fish can be a light purple to a deep violet starting at the head which fades mid-body to a golden yellow at the tail. The royal gramma will also have a small black spot on the front of the dorsal fin and a black line that streaks through the eye. It resembles the false gramma ('' Pictichromis paccagnellae''), with the two main differences between the two being the false gramma has clear fins and does not fade, but rather has a distinct change in color. The royal gramma is relatively small, averaging slightly over and has been tank bred. The largest scientifically-measured royal gramma was long. Diet The royal gramma is a planktivore, eating mostly zooplankton and crustaceans. The royal gramma is also a cleaner fish. It removes the ectoparas ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Taxa Named By David Starr Jordan
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lipogramma Trilineata
''Lipogramma trilineata'', the three-lined basslet, is a species of ray-finned fish from the family Grammatidae. It is found in the western Atlantic Ocean from the waters off southeastern Florida south through the Bahamas into the Gulf of Mexico and the Caribbean Sea as well as the coasts of Central and South America from Quintana Roo, Mexico to Nicaragua, and the seas off Cartagena and those off Venezuela at Curaçao and Bonaire. It occurs underneath rocky and coral ledges as well as occurring in deep reefs and on the outer wall at depths ranging from . Its range has been invaded by lionfish, an invasive species in the western Atlantic, which prey on a variety of fish species smaller than which means that both adults and juveniles ''L. trineata'' are likely prey of lionfish. It has been recorded that in the Bahamas, there has been a near two-thirds decline in the biomass of fish which lionfish prey on over a period of two years. Other species of basslet have been confirmed as p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gramma Melacara
The blackcap basslet (''Gramma melacara''), or blackcap gramma, is a species of fish inhabiting reefs in the tropical western Atlantic Ocean. It prefers vertical surfaces with crevices in which it can hide. It can be found at depths of from (usually between ). This species can also be found in the aquarium trade. Appearance A small fish, reaching a length of TL, it is purple with a diagonal black cap on its head. The body colour varies from magenta to purple, and there is a jet-black diagonal cap running from the lip to the foredorsal fin. The largest scientifically measured blackcap gramma was 10.0 cm / 3.9 inches. In the aquarium A hardy fish, it is typically peaceful, and can be kept in a reef aquarium. Care should be taken, however, to only add one fish to an aquarium, as they are territorial, and do not accept other members of the same, or similar looking, species in the same aquarium. Small shrimp also may get eaten by this fish. Because it likes to hide, it sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serranidae
The Serranidae are a large family of fishes belonging to the order Perciformes. The family contains about 450 species in 65 genera, including the sea basses and the groupers (subfamily Epinephelinae). Although many species are small, in some cases less than , the giant grouper (''Epinephelus lanceolatus'') is one of the largest bony fishes in the world, growing to in length and in weight. Representatives of this group live in tropical and subtropical seas worldwide. Characteristics Many serranid species are brightly colored, and many of the larger species are caught commercially for food. They are usually found over reefs, in tropical to subtropical waters along the coasts. Serranids are generally robust in form, with large mouths and small spines on the gill coverings. They typically have several rows of sharp teeth, usually with a pair of particularly large, canine-like teeth projecting from the lower jaw. All serranids are carnivorous. Although some species, especially i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Aquarium
A marine aquarium is an aquarium that keeps ocean, marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquarium, reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration. Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring. The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percomorpha
Percomorpha () is a large clade of ray-finned fish that includes the tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish. Evolution Percomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous-Paleogene boundary ca. 65 Ma ago. Phylogeny External relationships The two cladograms below are based on Betancur-R ''et al.'', 2017. Percomorphs are a clade of teleost fishes.

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
