Pinfish
''Lagodon'' is a genus of saltwater fish in the family Sparidae, the breams and porgies. It is monotypic, being represented by the single species ''Lagodon rhomboides'', commonly known as pinfish.Masterson, J''Lagodon rhomboides''.Smithsonian Marine Station at Fort Pierce. National Museum of Natural History, Smithsonian Institution. 2008. Other common names include pin perch, sand perch, choffer, and butterfish.90% of the diet for pinfish greater than 100mm. Predators The pinfish is prey for alligator gar, longnose gar, ladyfish, spotted sea trout, red drum, southern flounder, pelicans, grouper, cobia, snook and bottlenose dolphins. Reproduction Sexual maturity is reached at about one year, when the fish is 80 to 100 mm in length. Spawning season is in the fall and winter. Eggs are broadcast in the water by the female, then fertilized by the male. The number of eggs varies from 7,000 to 90,000. They hatch after about 48 hours. Larvae are not protected by adults.

John Edwards Holbrook
John Edwards Holbrook (December 31, 1796 – September 8, 1871) was an American zoologist, herpetologist, physician, and naturalist, born in Beaufort, South Carolina, the son of Silas Holbrook, a teacher, and Mary Edwards. Although Holbrook's memoir, written by his medical partner, and his tombstone both give the date 1794 for his birth, this is incorrect. Holbrook received his A.B. degree from Brown University in 1815, and his M.D. from the University of Pennsylvania in 1818. In 1827, he married Harriott Pinckney Rutledge (1802–1863), granddaughter of John Rutledge and a member of the Middleton-Rutledge-Pinckney family. He provided the first comprehensive illustrated account of North American amphibians and reptiles in the two editions of his ''North American Herpetology; or, A Description of the Reptiles Inhabiting the United States''. The first edition in four volumes (1836–1840) is very rare because Holbrook attempted to destroy all copies in a bonfire in his backyard over ...

Red Drum
The red drum (''Sciaenops ocellatus''), also known as redfish, channel bass, puppy drum, spottail bass, or simply red, is a game fish found in the Atlantic Ocean from Massachusetts to Florida and in the Gulf of Mexico from Florida to northern Mexico. It is the only species in the genus ''Sciaenops''. The red drum is related to the black drum (''Pogonias cromis''), and the two species are often found near to each other; they can interbreed and form a robust hybrid, and younger fish are often indistinguishable in flavor. Characteristics Red drum are a dark red color on the back, which fades into white on the belly. The red drum has a characteristic eyespot near the tail and is somewhat streamlined. Three-year-old red drum typically weigh 6-8 lb. The largest red drum on record weighed just over 94 lb and was caught in 1984 on Hatteras Island. Male red drum make a knocking or drumming sound during spawning by vibrating their swim bladders. The most distinguishing mark on the red ...

Seagrass
Seagrasses are the only flowering plants which grow in marine environments. There are about 60 species of fully marine seagrasses which belong to four families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow leaves, which grow by rhizome extension and often spread across large "meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed this pollination was carried out without pollina ...

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cynoscion Nebulosus
''Cynoscion nebulosus'', the spotted seatrout, also known as speckled trout, is a common estuarine fish found in the southern United States along coasts of Gulf of Mexico and the coastal Atlantic Ocean from Maryland to Florida. While most of these fish are caught on shallow, grassy flats, spotted seatrout reside in virtually any inshore waters, from the surf of outside islands to far up coastal rivers, where they often come for shelter during cold weather. Contrary to its name, the spotted seatrout is not a member of the trout family ( Salmonidae), but of the drum family ( Sciaenidae). It is popular for commercial and especially recreational fishing in coastal waters of the southeastern United States. Adults reach 19-37 inches in length and 3-17 pounds in weight. Distribution Spotted seatrout live in the top of the water column and are most numerous along the coasts of the southeastern states, such as Texas, Louisiana, Alabama, Mississippi, Georgia, and Florida. They are also com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elopidae
The Elopidae are a family of ray-finned fish containing a single living genus '' Elops''. They are commonly known as ladyfish, skipjacks, jack-rashes, or tenpounders. The ladyfish are a coastal-dwelling fish found throughout the tropical and subtropical regions, occasionally venturing into temperate waters.Adams, A. J., Horodysky, A. Z., McBride, R.

Longnose Gar
The longnose gar (''Lepisosteus osseus''), also known as longnose garpike or billy gar, is a ray-finned fish in the family Lepisosteidae. The genus may have been present in North America for about 100 million years. References are made to gars being a primitive group of bony fish because they have retained some primitive features, such as a spiral valve intestine, but they are not primitive in the sense of not being fully developed. They have an olive brown to green, torpedo-shaped body armored with ganoid scales, elongated jaws that form a needle-like snout nearly three times the length of its head, and a row of numerous sharp, cone-shaped teeth on each side of the upper jaw. They typically inhabit freshwater lakes, brackish water near coastal areas, swamps, and sluggish backwaters of rivers and streams. They can breathe both air and water, which allows them to inhabit aquatic environments that are low in oxygen. Longnose gar are found along the east coasts of North and C ...

Alligator Gar
The alligator gar (''Atractosteus spatula'') is a ray-finned euryhaline fish related to the bowfin in the infraclass Holostei . It is the largest species in the gar family, and among the largest freshwater fish in North America. The fossil record traces its group's existence back to the Early Cretaceous over 100 million years ago. Gars are often referred to as " primitive fishes", or "living fossils" because they have retained some morphological characteristics of their early ancestors, such as a spiral valve intestine, which is also common to the digestive system of sharks, and the ability to breathe both air and water. Their common name was derived from their resemblance to the American alligator, particularly their broad snouts and long, sharp teeth. Anecdotal evidence suggests that an alligator gar can grow up to in length. The body of an alligator gar is torpedo-shaped, usually brown or olive, fading to a lighter gray or yellow ventral surface. In very rare occ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphipod
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polychaete
Polychaeta () is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes (). Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm (''Arenicola marina'') and the sandworm or clam worm ''Alitta''. Polychaetes as a class are robust and widespread, with species that live in the coldest ocean temperatures of the abyssal plain, to forms which tolerate the extremely high temperatures near hydrothermal vents. Polychaetes occur throughout the Earth's oceans at all depths, from forms that live as plankton near the surface, to a 2- to 3-cm specimen (still unclassified) observed by the robot ocean probe ''Nereus'' at the bottom of the Challenger Deep, the deepest known spot in the Earth's oceans. Only 168 species (less than 2% of all polychaetes) are known from fresh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barnacle
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale (whale barnacles), a sea snake (''Platylepas ophiophila''), or another crustacean, like a crab or a lobster (Rhizocephala). The most common among them, "acorn barnacles" (Sessilia), are sessile where they grow their shells directly onto the substrate. Pedunculat ...

Shoaling And Schooling
In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling. In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives. Fish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate. It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency. Fish use many traits to choose shoalmates. Generally they prefer larger shoals, shoalmates of their own species, shoalmates similar in size and appearance to themselves, healthy fish, and kin (when recognized). The oddity effect posits that any shoal member that stands out in appearance will be preferen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
