Carangidae
The Carangidae are a family of ray-finned fish which includes the jacks, pompanos, jack mackerels, runners, and scads. It is the largest of the six families included within the order Carangiformes. Some authorities classify it as the only family within that order but molecular and anatomical studies indicate that there is a close relationship between this family and the five former Perciform families which make up the Carangiformes. They are marine fishes found in the Atlantic, Indian and Pacific Oceans. Most species are fast-swimming predatory fishes that hunt in the waters above reefs and in the open sea; some dig in the sea floor for invertebrates. The largest fish in the family, the greater amberjack, ''Seriola dumerili'', grows up to 2 m in length; most fish in the family reach a maximum length of 25–100 cm. The family contains many important commercial and game fish, notably the Pacific jack mackerel, ''Trachurus symmetricus'', and the other jack mackerels in ...

Damselfish
Damselfish are those within the subfamilies Abudefdufinae, Chrominae, Lepidozyginae, Pomacentrinae, and Stegastenae within the family Pomacentridae. Most species within this group are relatively small, with the largest species being about 30cm (12 in) in length. Most damselfish species exist only in marine environments, but a few inhabit brackish or fresh water. These fish are found globally in tropical, subtropical, and temperate waters. Habitat in tropical rocky or coral reefs, and many of those are kept as marine aquarium pets. Their diets include small crustaceans, plankton, and algae. However, a few live in fresh and brackish waters, such as the freshwater damselfish, or in warm subtropical climates, such as the large orange Garibaldi, which inhabits the coast of southern California and the Pacific Mexican coast. Foraging The domino damselfish '' D. albisella'' spends the majority (greater than 85%) of its daytime hours foraging. Larger individuals typically fo ...

Squirrelfish
Holocentrinae is a subfamily of Holocentridae containing 40 recognized species and one proposed species. Its members are typically known as squirrelfish and all are nocturnal. All three genera in the subfamily are found in the Atlantic and ''Holocentrus'' is restricted to this ocean. Most species in genera ''Neoniphon'' and ''Sargocentron'' are from the Indo-Pacific region and several of these occur in the Indian Ocean west of the southern tip of India.Randal, J.E. and Heemstra, P.C. 1985"A review of the squirrelfishes of the subfamily Holocentrinae from the Western Indian Ocean and Red Sea" ''Ichthyological Bulletin of the J.L.B.

Hawksbill Sea Turtle
The hawksbill sea turtle (''Eretmochelys imbricata'') is a critically endangered sea turtle belonging to the family Cheloniidae. It is the only extant species in the genus ''Eretmochelys''. The species has a global distribution, that is largely limited to tropical and subtropical marine and estuary ecosystems. The hawksbill's appearance is similar to that of other marine turtles. In general, it has a flattened body shape, a protective Carapace#Turtles and tortoises, carapace, and flipper (anatomy), flipper-like limbs, adapted for swimming in the open ocean. ''E. imbricata'' is easily distinguished from other sea turtles by its sharp, curving beak with prominent tomium, and the wikt:serration, saw-like appearance of its shell margins. Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs.

Blacktip Shark
The blacktip shark (''Carcharhinus limbatus'') is a species of requiem shark, and part of the family Carcharhinidae. It is common to coastal tropical and subtropical waters around the world, including brackish habitats. Genetic analyses have revealed substantial variation within this species, with populations from the western Atlantic Ocean isolated and distinct from those in the rest of its range. The blacktip shark has a stout, fusiform body with a pointed snout, long gill slits, and no ridge between the dorsal fins. Most individuals have black tips or edges on the pectoral, dorsal, pelvic, and caudal fins. It usually attains a length of . Swift, energetic piscivores, blacktip sharks are known to make spinning leaps out of the water while attacking schools of small fish. Their demeanor has been described as "timid" compared to other large requiem sharks. Both juveniles and adults form groups of varying size. Like other members of its family, the blacktip shark is viviparous; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schoolmaster Snapper
The schoolmaster snapper (''Lutjanus apodus''), also known as the dogtooth snapper, is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is found in the western Atlantic Ocean. Like other snapper species, it is a popular food fish. Taxonomy The schoolmaster snapper was first formally described in 1792 as ''Perca apoda'' by the German physician, naturalist and taxonomist Johann Julius Walbaum with the type locality given as the Bahamas. Walbaum's description was based on an illustration which omitted the fish's pectoral fins, so he gave it the specific name ''apoda'' meaning "footless". Description The schoolmaster snapper has a moderately deep body which is robust and slightly compressed with a long. pointed snout and a large mouth. One of the upper pairs of canine teeth is clearly larger than back teeth in the lower jaw and can be seen when mouth is closed. The vomerine teeth are arranged in a chevron or crescent shaped patch with a lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Chromis
''Chromis cyanea'' (blue chromis) is a damselfish in the subfamily ''Pomacentrinae'', found in Bermuda, southern Florida and the Caribbean Sea. It is collected for the aquarium trade. Habitat and ecology Being a shallow water fish, the blue chromis is commonly found at depths of 3 to 5 m, but it can reach depths of 25 m below sea level. It's also been recorded at a depth of 60 m below sea level. It lives on the surface of reefs, but often swims in the water columns above the reefs to feed on plankton. Behaviour It's a rather solitary species, seen alone or in small groups, and tends to stay close to the reefs. The younger fish stay near the bottom in order to avoid predators. The males maintain a solitary breeding territory. After breeding with multiple females, they guard the eggs until the planktonic larvae hatch. Use and trade The blue chromis is largely collected for use in aquariums. There are no reliable numbers on the extent of this collecting, but damself ...
