Like other species in its genus, the ladyfish has a long, slender, rounded body covered with silvery scales. Its mouth is terminal and the tail is deeply forked. The species can be distinguished by counting the number of gill rakers and vertebrae. [4]

Distribution

The ladyfish is distributed in the western North Atlantic Ocean from New England to Florida, and the Gulf of Mexico. [4] Its distribution overlaps with the malacho ( Elops smithi ) in the southeast US and the southern Gulf of Mexico. [5]

Biology

Like other members of the Elopidae, the ladyfish is a pelagic fish that spawns in the sea, but little is known about this marine phase. The larvae, which are transparent and laterally compressed, are dispersed inshore and enter embayments, where they live for 2 to 3 yr. [5] [6] The juveniles are euryhaline, or tolerant to a wide range of salinity, so these embayments may be low-salinity estuaries or hypersaline lagoons. [7] Subadults move into the lower reaches of the embayments, and upon maturation, proceed to offshore, marine habitats.

Threats

This species uses estuarine areas and hypersaline lagoons; changes in the quality of these habitats may affect this species' population dynamics. Although this species may not be closely associated with any single habitat, it may be adversely affected by development and urbanization. [8]

<span class="mw-page-title-main">Crevalle jack</span> Species of fish

The crevalle jack, also known as the common jack, black-tailed trevally, couvalli jack, black cavalli, jack crevale, or yellow cavalli is a common species of large marine fish classified within the jack family, Carangidae. The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean, ranging from Nova Scotia, Canada to Uruguay in the western Atlantic and Portugal to Angola in the eastern Atlantic, including the Mediterranean Sea. It is distinguishable from similar species by its deep body, fin colouration and a host of more detailed anatomical features, including fin ray and lateral line scale counts. It is one of the largest fish in the genus Caranx, growing to a maximum known length of 124 cm and a weight of 32 kg, although is rare at lengths greater than 60 cm. The crevalle jack inhabits both inshore and offshore waters to depths of around 350 m, predominantly over reefs, bays, lagoons and occasionally estuaries. Young fish dispersed north by currents in the eastern Atlantic are known to migrate back to more tropical waters before the onset of winter; however, if the fish fail to migrate, mass mortalities occur as the temperature falls below the species' tolerance.

The Hawaiian ladyfish, also known as the Hawaiian tenpounder or banana fish, is a species of ray-finned fish in the family Elopidae. It is sometimes referred to as the giant herring, though it is not closely related to the true herrings of the family Clupeidae. Its Hawaiian name is awa 'aua. It is native to the west central Pacific Ocean, and the current classification may in fact consist of several species.

The Atlantic tarpon is a ray-finned fish that inhabits coastal waters, estuaries, lagoons, and rivers. It is also known as the silver king. It is found in the Atlantic Ocean, typically in tropical and subtropical regions, though it has been reported as far north as Nova Scotia and the Atlantic coast of southern France, and as far south as Argentina. As with all elopiformes, it spawns at sea. Its diet includes small fish and crustaceans.

Albula glossodonta is a type of marine fish found in the Pacific Ocean. They grow up to 70 cm. Shortjaw bonefish are important to food security throughout the coastal Pacific where they are native as Pacific island communities depend on this fish for food.
