Bothidae

Lefteye flounders are a family, Bothidae, of . They are called "lefteye flounders" because most species lie on the sea bottom on their right side, with both eyes on the left side. A helpful reminder when trying to recall the family name for this fish is that "Bothidae eyes are on the same side o' dey head." The family is also distinguished by the presence of spines on the snout and near the eyes. [more]

Found mainly in the tropical waters of the western Indo-Pacific, the family contains approximately 186 species in 18 genera. The Draconettidae may be considered a sister family, whose members are very much alike though rarely seen. Due to similarities in morphology and behaviour, dragonets are sometimes confused with members of the goby family. [more]

Caproidae

Boarfishes are a small family, Caproidae, of fishes comprising two genera and twelve species. They are usually placed in the order Zeiformes with the dories, but this placement is uncertain, since boarfishes have many perciform characters, for instance in the caudal skeleton.

Centropomidae

The Centropomidae are a single family of freshwater and marine fishes in Order Perciformes, including the common snook or róbalo, Centropomus undecimalis. Prior to 2004, three other genera were placed in Centropomidae in subfamily Latinae, which has since been raised to the family level and renamed Latidae because a cladistic analysis showed the old Centropomidae to be paraphyletic. Each of the four species (fat, swordspine, common, and tarpon) can be easily identified by their lateral black line. They are good tablefare, and are a sought after gamefish but tricky to catch. [more]

Within the family are nine genera and 20 species. Juveniles are known as tapetails and were formerly thought to be in a separate family, dubbed Mirapinnidae. Adults exhibit extreme sexual dimorphism, and the adult males were once thought to be exemplars of still another family, Megalomycteridae. [more]

Chaenopsidae

The family Chaenopsidae includes the pike-blennies, tube-blennies and flagblennies: all perciform marine fish. The family is strictly tropical, ranging from North to South America. There are 14 genera and 90 species represented, the largest being the sarcastic fringehead, Neoclinus blanchardi, at 30 centimetres (12 in) in length; most are much smaller, and the group includes perhaps the smallest of all vertebrates, Acanthemblemaria paula, measuring just 1.3 centimetres (0.51 in) long as an adult. [more]

Chaetodontidae

The butterflyfish are a group of conspicuous tropical marine of the family Chaetodontidae; the bannerfish and coralfish are also included in this group. Found mostly on the reefs of the Atlantic, Indian and Pacific Oceans, there are approximately 120 species in 10 genera. A number of species pairs occur in Indian and Pacific ocean, members of the huge genus Chaetodon, and their taxonomy has often been confused by whether these should be considered species or subspecies. Recent work using DNA sequence data has resolved many of these questions. Also, numerous subgenera have been proposed for splitting out of Chaetodon, and it is becoming clear how the genus ought to be subdivided if that is desired. [more]

Champsodontidae

[more]

Channichthyidae

The crocodile icefishes or white-blooded fishes (Channichthyidae) are a of perciform fish found in the cold waters around Antarctica and southern South America. Fifteen species of crocodile icefish are known. They feed on krill, copepods, and other fish. [more]

There are at least 1300 scientifically described species, making it one of the largest vertebrate families. Numerous new species are discovered annually, and many species remain undescribed. The actual number of species is therefore unclear, with estimates varying between 1300 and 3000 species, and one source suggesting 1900 species. Cichlids span a wide range of body sizes, from species as small as 2.5 centimetres (1.0 in) in length (e.g. female Neolamprologus multifasciatus ) to much larger species approaching 1 metre (3 ft) in length (e.g. Boulengerochromis and Cichla). As a group, cichlids exhibit a similarly wide diversity of body shapes, ranging from strongly laterally compressed species (such as Altolamprologus, Pterophyllum, and Symphysodon) through to species that are cylindrical and highly elongate (such as Julidochromis, Teleogramma, Teleocichla, Crenicichla, and Gobiocichla). Generally, however, cichlids tend to be of medium size, ovate in shape and slightly laterally compressed, and generally very similar to the North American sunfishes in terms of morphology, behaviour, and ecology.

Like the Callionymids, they are bottom-dwelling fish, and usually sexually dimorphic. [more]

Echeneidae

Remoras or suckerfish are elongated brown in order Perciformes and family Echeneidae. They grow to 30–90 centimetres long (1–3 ft), and their distinctive first dorsal fin takes the form of a modified oval sucker-like organ with slat-like structures that open and close to create suction and take a look firm hold against the skin of larger marine animals. By sliding backward, the remora can increase the suction, or it can release itself by swimming forward. Remoras sometimes attach to small boats. They swim well on their own, with a sinuous motion. [more]

Elassomatidae

Elassoma is a of freshwater fish, the only member of family Elassomatidae and suborder Elassomatoidei of order Perciformes. The type species is E. zonatum, the banded pygmy sunfish. The Elassomatidae are known collectively as pygmy sunfishes, but are not true sunfishes, which are members of family Centrarchidae. Some researchers believe they are related to sticklebacks and pipefishes (order Syngnathiformes) rather than Perciformes. [more]

Eleotridae

Sleeper gobies are members of the Eleotridae family, found predominantly in the tropical Indo-Pacific. There are approximately 35 genera and 150 species. While many eleotrids pass through a planktonic stage in the sea and some spend their entire lives in the sea, as adults the majority live in freshwater streams and brackish waters. They are especially important as predators in the freshwater stream ecosystems on oceanic islands such as New Zealand and Hawai'i that otherwise lack the predatory fish families typical of nearby continents, such as catfish. Anatomically they are similar to the gobies (Gobiidae), though unlike the majority of gobies, they do not have a pelvic sucker. [more]

Ephippidae

Ephippidae is the fish family containing the spadefishes. There are about eight genera with a total of 20 species, mostly marine. The most well-known species are probably those in the genus Platax, the batfishes, which are kept as aquarium fish. They are spade-shaped, laterally compressed, and very symmetrical triangular dorsal and anal fins. They are shiny silver with areas of yellow and vertical brown or black banding. The eyes are often located in one of the vertical bands as a method of camouflage. Scuba divers sometimes mistake them for angelfish, which are similar in shape but not closely related. Other genera in the family are characterized by long, trailing, pointed dorsal and anal fins. Most species feed primarily on algae and small invertebrates. [more]

The moorish idol, Zanclus cornutus ("Crowned Scythe"), is a small marine fish, the sole representative of the family Zanclidae (from the Greek zagkios, "oblique"). A common inhabitant of tropical to subtropical reefs and lagoons, the moorish idol is notable for its wide distribution throughout the Indo-Pacific. A number of butterflyfishes (all of the genus Heniochus) closely resemble the moorish idol. [more]

Zaproridae

Prowfish (Zaprora silenus) are subtropical marine fish found in the North Pacific. They are the only member of their family, Zaproridae. They should not be confused with the Australian prowfish of the unrelated family Pataecidae. [more]

Zeidae

The Zeidae (named after , the supreme god of Greek mythology) are a family of large, showy, deep-bodied zeiform marine fish—the "true dories". Found in the Atlantic, Indian, and Pacific Ocean, the family contains just six species in two genera. All species are important and highly-regarded food fish supporting commercial fisheries, and some—such as the John dory (Zeus faber)—are enjoyed in large public aquaria. These fish are caught primarily via deep-sea trawling. [more]

Zoarcidae

The eelpouts are the family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance, with elongate bodies, and the dorsal and anal fins continuous with the caudal fin. All of the approximately 220 species are marine, mostly bottom-dwelling, some at great depths. They are sometimes called "fish doctors" (not to be confused with the doctorfish or surgeon fishes). [more]

At least 388 species and subspecies belong to the Family Zoarcidae.
