Serranidae
Serranidae is a large family (biology), 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 (tooth), canine-like teeth projecting from the lower jaw. All serranids are carnivorous.

Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudanthias
''Pseudanthias'' is a genus of colourful reef fishes of the subfamily Anthiinae, part of the family Serranidae, the groupers and sea basses. They are found in the Indo-Pacific. The species belonging to this genus have a diet consisting of zooplankton, and are haremic. Fishes currently included in this genus were earlier part of the genus ''Anthias''. ''Pseudanthias'' is the largest anthiine genus Species These are the 66 currently recognized species in this genus: * '' Pseudanthias albofasciatus'' ( Fowler & B. A. Bean, 1930) * '' Pseudanthias aurulentus'' ( J. E. Randall & McCosker, 1982) * '' Pseudanthias bartlettorum'' ( J. E. Randall & Lubbock, 1981) (Bartletts' anthias) * '' Pseudanthias bicolor'' ( J. E. Randall, 1979) (Bicolor anthias) * '' Pseudanthias bimaculatus'' (J. L. B. Smith, 1955) (Two-spot basslet) * '' Pseudanthias bimarginatus'' J. E.

Grouper
Groupers are a diverse group of marine ray-finned fish in the family Epinephelidae, in the order Perciformes. Groupers were long considered a subfamily of the seabasses in Serranidae, but are now treated as distinct. Not all members of this family are called "groupers". The common name "grouper" is usually given to fish in one of two large genera: ''Epinephelus'' and '' Mycteroperca''. In addition, the species classified in the small genera ''Anyperidon'', ''Cromileptes'', ''Dermatolepis'', ''Graciela'', ''Saloptia'', and ''Triso'' are also called "groupers". Fish in the genus '' Plectropomus'' are referred to as "coral groupers". These genera are all classified in the subfamily Epiphelinae. However, some of the hamlets (genus ''Alphestes''), the hinds (genus ''Cephalopholis''), the lyretails (genus ''Variola''), and some other small genera (''Gonioplectrus'', ''Niphon'', ''Paranthias'') are also in this subfamily, and occasional species in other serranid genera have common na ...

Protogynous
Sequential hermaphroditism (called dichogamy in botany) is one of the two types of hermaphroditism, the other type being simultaneous hermaphroditism. It occurs when the organism's sex changes at some point in its life. A sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Sequential hermaphroditism occurs in many fish, gastropods, and plants. Species that can undergo these changes do so as a normal event within their reproductive cycle, usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), and bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex chan ...

Giant Grouper
The giant grouper (''Epinephelus lanceolatus''), also known as the Queensland groper (grouper), brindle grouper or mottled-brown sea bass, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It has a wide Indo-Pacific distribution and is one of the largest extant species of bony fish. Description The giant grouper has a robust body which has a standard length equivalent to 2.4 to 3.4 times its depth. The dorsal profile of the head and the intraorbital area are convex. The propercle has a rounded corner and a finely serrated margin. The gill cover has a convex upper margin. There are 11 spines and 14–16 soft rays in the dorsal fin while the anal fin has 3 spines and 8 soft rays. The caudal fin is slightly rounded. There are 54 to 62 scales in its lateral line. The adults are grayish-brown in colour overlain with a mottled pattern and with darker fins. The smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Bass
Sea bass is a common name for a variety of species of marine fish. Many fish species of various families have been called sea bass. In Ireland and the United Kingdom, the fish sold and consumed as sea bass is exclusively the European bass, ''Dicentrarchus labrax''. Sometimes referred to as sea bass include the following: Family Serranidae Family Serranidae * Genus '' Paralabrax'' ** Barred sand bass (''Paralabrax nebulifer'') lives mainly off the coast of California. * Genus '' Centropristis'' ** Black sea bass (''Centropristis striata'') is found on the East Coast of the United States. * Genus '' Caesioperca'' ** Butterfly perch (''Caesioperca Lepidoptera'') is found in the eastern Indian Ocean and the southwest Pacific Ocean, including southern Australia and New Zealand. * Genus '' Caprodon'' ** Pink maomao (''Caprodon longimanus'') is found in the eastern Indian Ocean and the southern Pacific Ocean, including Australia and New Zealand. * Genus ''Epinephelus'' ** Potato cod ( ...

Humpback Grouper
The humpback grouper (''Cromileptes altivelis''), also known as the panther grouper, (in Australia) barramundi cod, (in the Philippines, in Tagalog) lapu-lapung senorita, (in the Philippines, in Bisayan) miro-miro, (in Japan) sarasa-hata, (in India) kalava, and many other local names, is a species of marine ray-finned fish. Specifically, it is a grouper from the subfamily Epinephelinae, which is in the family Serranidae, which also includes the anthias and sea basses. It occurs in the Western Pacific Ocean. Systematics The humpback grouper was first formally described as ''Serranus altivelis'' in 1828 by the French zoologist Achille Valenciennes (1794–1865) with the type locality given as Java. In 1839, the English naturalist William Swainson (1789–1855) placed it in the subgenus ''Chromileptes'', which was later created as a monotypic genus. Swainson spelt the genus as ''Chromileptes'' although Fishbase spells it as ''Cromileptes''. Recent molecular analyses based on ...

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Bony Fish
Osteichthyes ( ; ), also known as osteichthyans or commonly referred to as the bony fish, is a Biodiversity, diverse clade of vertebrate animals that have endoskeletons primarily composed of bone tissue. They can be contrasted with the Chondrichthyes (cartilaginous fish) and the extinct placoderms and acanthodians, which have endoskeletons primarily composed of cartilage. The vast majority of extant taxon, extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 order (biology), orders, over 435 family (biology), families and 28,000 species. The group is divided into two main clades, the ray-finned fish (Actinopterygii, which makes up the vast majority of extant fish) and the lobe-finned fish (Sarcopterygii, which gave rise to all land vertebrates, i.e. tetrapods). The oldest known fossils of bony fish are about 425 million years old from the late Silurian, which are also transitional fossils showing a dentition, tooth pattern th ...

Monogenea
Monogeneans, members of the class Monogenea, are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.L.A. Tubbsa et al. (2005). "Effects of temperature on fecundity in vitro, egg hatching and reproductive development of ''Benedenia seriolae'' and ''Zeuxapta seriolae'' (Monogenea) parasitic on yellowtail kingfish Seriola lalandi". ''International Journal for Parasitology''(35), 315–327. Some monogeneans are oviparous (egg-laying) and some are viviparous (live-bearing). Oviparous varieties release eggs into the water. Viviparous varieties release larvae, which immediately attach to another host. The genus ''Gyrodactylus'' is an example of a viviparous variety, while the genus ''Dactylogyrus'' is an example of an oviparous variety. Signs and symptoms Freshwater fish that become infect ...
