Triggerfish
Triggerfish are about 40 species of often brightly colored marine ray-finned fishes belonging to the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish (''Canthidermis maculata''), are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered. Taxonomy The triggerfish family, Balistidae, was first proposed in 1810 by the French polymath Constantine Samuel Rafinesque. The closest relatives to the triggerfishes are the filefishes belonging to the family Monacanthidae and these two families are sometimes classified together in the suborder Balistoidei, for example in the 5th edition of ''Fishes of the World''. Other authorities, however, also include the famili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Balistes Vegai
''Balistes'' is a genus of marine Actinopterygii, ray-finned fishes belonging to the Family (biology), family Balistidae, the triggerfishes. The triggerfishes in this genus are found in the Atlantic and eastern Pacific Ocean. Taxonomy ''Balistes'' was first proposed as a genus by Carl Linnaeus in the 10th edition of Systema Naturae, 10th edition of ''Systema Naturae'' publishes in 1758. In 1865 Pieter Bleeker designated ''Balistes veluta'' as the type species of the genus. When he Species description, described ''B. veluta'' Linnaeus gave its Type locality (biology), type locality as Ascension Island. This genus is the type genus of the family Balistidae, which is classified in the suborder Balistoidei in the Order (biology), order Tetraodontiformes. A 2016 study found that ''Balistes'' was non-monophyletic and stated that moving ''Pseudobalistes naufragium'' to ''Balistes naufragium'' while also moving ''Balistoides viridescens'' to ''Pseudobalistes viridescens'' results in ''Ba ...

Lagoon Triggerfish
The lagoon triggerfish (''Rhinecanthus aculeatus''), also known as the blackbar triggerfish, the Picasso triggerfish, or the Picassofish, is a triggerfish, up to in length, found on reefs in the Indo-Pacific region. This species has been studied in a range of research contexts, from locomotion to color vision research. Behavior Lagoon triggerfish live in the reefs and sandy areas of coral reefs, where they eat just about anything that comes along, mostly including invertebrates and reef algae. They are always restlessly swimming around and vigorously protect their territory against intruders, including divers, especially when guarding their eggs during reproduction season. Their relatively small size makes them much less dangerous than the larger titan triggerfish of the same family. The fish moves through the water by using waving motions in its dorsal and anal fins, allowing it to move more precisely. Using these movements, it can move forwards, backwards or simply hover in ...

Oceanic Triggerfish
''Canthidermis '' is a genus of triggerfishes commonly known as ocean triggerfishes. Species There are currently 3 recognized species in this genus: * ''Canthidermis macrolepis'' George Albert Boulenger, Boulenger, 1888 (Large-scale triggerfish) * ''Canthidermis maculata'' Marcus Elieser Bloch, Bloch, 1786 (Spotted oceanic triggerfish) * ''Canthidermis sufflamen'' Samuel Latham Mitchill, Mitchill, 1815 (Ocean Triggerfish) Description These dark-colored triggerfishes are found in all the world's oceans in tropical and subtropical areas. They are absent in the Mediterranean. Unlike most triggerfish they are epipelagic. They usually live far away from the coast in the microhabitat created by floating objects like trees, or branches, but also plastic wreck remains, ropes and other large flotsam and jetsam items. There is still little research on the feeding and reproduction habits of these fish. They are rarely part of the catch unless the marine debris around which they live reac ...

Stone Triggerfish
The stone triggerfish (''Pseudobalistes naufragium'') is the largest species of triggerfish. Distribution It is found at reefs and over sandy bottoms in the eastern Pacific, ranging from Baja California Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northwesternmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of B ... (Mexico) to Chile. Description It can reach in length, but is more common at about half that size. Covered entirely with platelike scales aside from one scaleless area behind the jaws, the stone triggerfish has 16 strong protruding teeth, with 8 held in each jaw. Diet ''Pseudobalistes naufragium'' feeds on small crustaceans, mollusks, and sea urchins. Gallery File:Pseudobalistes naufragium, Coiba N.P.

Filefish
The filefish (Monacanthidae) are a diverse family of tropical to subtropical tetraodontiform marine fish, which are also known as foolfish, leatherjackets, or shingles. They live in the Atlantic, Pacific, and Indian Oceans. Filefish are closely related to triggerfish, pufferfish, and trunkfish. The filefish family comprises about 102 species in 27 genera. More than half of the species are found in Australian waters, with 58 species in 23 genera. Their laterally compressed bodies and rough, sandpapery skin inspired the filefish's common name. Description Appearing very much like their close relatives the triggerfish, filefish are rhomboid-shaped, with beautifully elaborate cryptic patterns. Deeply keeled bodies give a false impression of size when the fish are viewed facing the flanks. Filefish have soft, simple fins, with comparatively small pectoral fins and truncated, fan-shaped tail fins; a slender, retractable spine crowns the head. Although usually two of these spines oc ...

Aracanidae
Aracanidae, the deep sea boxfishes or temperate boxfishes, are a family of marine ray-finned fishes belonong to the order Tetraodontiformes, which also includes the pufferfishes, triggerfishes and ocean sunfishes. The fishes in this family are found in the Indo-West Pacific region, particularly in the waters around Australia. Taxonomy ''Aracanidae'' was first proposed as a family in 1860 by the Swiss-born French biologist Henri Louis Gabriel Marc Hollard. In the past this taxon was regarded as a subfamily of the Ostraciidae. However, recent phylogenetic studies have concluded that the families Aracanidae and Ostraciidae are valid families but that they are part of the same clade, the suborder Ostracioidei. The 5th edition of ''Fishes of the World'' classifies this clade as the suborder Ostracioidea within the order Tetraodontiformes. Genera Aracanidae contains the following six extant and single extinct genera: means extinct. Etymology Aracanidae takes its name from its ty ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, ...

Balistoidei
Balistoidei, or Sclerodermi, is a suborder of Actinopterygii, ray-finned fishes belonging to the Order (biology), order Tetraodontiformes, the order which includes the pufferfishes, ocean sunfishes, boxfishes and related fishes. This suborder comprises two extant and three extinct families, the extant species in this taxon are widespread throughout the tropical and temperate seas of the world. Taxonomy Balistoidei was proposed as a taxonomic grouping by Rafinesque in 1810 and is recognised by the 5th edition of the ''Fishes of the World'' as a suborder of the order Tretraodontiformes. Eschmeyer's ''Catalog of Fishes'' also recognises the Balistoidei but includes the Aracanidae and the Ostraciidae within it. On the other hand, other authorities do not recognise any taxa between the level of family and suborder in their Tetraodontoidei. Families Balistoidei contains the following famlilies: * Bolcabalistidae Francesco Santini, Santini & James C. Tyler, Tyler, 2003 * Moclaybalistida ...

Ballista
The ballista (Latin, from Ancient Greek, Greek βαλλίστρα ''ballistra'' and that from βάλλω ''ballō'', "throw"), plural ballistae or ballistas, sometimes called bolt thrower, was an Classical antiquity, ancient missile weapon that launched either Crossbow_bolt, bolts or stones at a distant target. Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod (the bow part of a modern crossbow). The springs consisted of several loops of twisted Hank (textile), skeins. Early versions projected heavy dart (missile), darts or spherical stone projectiles of various sizes for siege warfare. It developed into a smaller precision weapon, the ''Scorpio (weapon), scorpio'', and possibly the ''polybolos''. Greek weapon The early ballistae in Ancient Greece were developed from two weapons called oxybeles and gastraphetes. The gastraphetes ('belly-bow') was a handheld crossbow. It had a composite p ...

Type Genus
In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens ...

Suborder
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consistent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
