Elopidae
The Elopidae are a family (biology), 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.

Elops Saurus
The ladyfish or tenpounder (''Elops saurus'') is a species of fish in the genus ''Elops'', the only genus in the monotypic family Elopidae. Description 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. Distribution The ladyfish is distributed in the western North Atlantic Ocean from New England to Florida, and the Gulf of Mexico. Its distribution overlaps with the malacho ('' Elops smithi'') in the southeast US and the southern Gulf of Mexico. 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. The juveniles are euryhaline, or tolerant to a wide range of ...

Elops Hawaiensis
The Hawaiian ladyfish (''Elops hawaiensis''), also known as the Hawaiian tenpounder or banana fish, is a species of ray-finned fish in the family Elopidae.

Some have been known to grow to . 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.Adams, A. J., Horodysky, A. Z., McBride, R.

The Pacific ladyfish (''Elops affinis''), also known as the Pacific tenpounder and machete, is a species of ray-finned fish in the genus ''Elops'', the only genus in the monotypic family Elopidae.

Davichthys
''Davichthys'' is an extinct genus of prehistoric marine ray-finned fish related to modern ladyfish. It is known from the Late Cretaceous of southern Europe, the Middle East, and North Africa. It is one of the earliest known elopids. Taxonomy The following species are known: * †''D. dubius'' (Davis, 1887) - Late Santonian of Lebanon ( Sahel Alma) (='' Osmeroides dubius'' Davis, 1887) * †''D. gardneri'' Forey, 1973 - Late Cenomanian of Lebanon ( Sannine Formation) * †''D. lacostei'' ( Arambourg, 1954) - Late Cenomanian of Italy ( Scaglia Variegata Alpina Formation, Scaglia Bianca Formation) including Sicily ( Argille Varicolori Formation), and Morocco ( Jbel Tselfat) (=''Holcolepis lacostei'' Arambourg, 1954) Description This fish was usually less than 15 centimeters long, and its appearance must have been very similar to that of the modern ''Elops'' . Like the latter, ''Davichthys'' had an elongated body with an oval cross-section, slightly flattened laterally. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elapidae
Elapidae (, commonly known as elapids , from , variant of "sea-fish") is a family of snakes characterized by their permanently erect fangs at the front of the mouth. Most elapids are venomous, with the exception of the genus '' Emydocephalus''. Many members of this family exhibit a threat display of rearing upwards while spreading out a neck flap. Elapids are endemic to tropical and subtropical regions around the world, with terrestrial forms in Asia, Australia, Africa, and the Americas and marine forms in the Pacific and Indian Oceans. Members of the family have a wide range of sizes, from the white-lipped snake to the king cobra. Most species have neurotoxic venom that is channeled by their hollow fangs, and some may contain other toxic components in varying proportions. The family includes 55 genera with around 360 species and over 170 subspecies. Description Terrestrial elapids look similar to the Colubridae; almost all have long, slender bodies with smooth scales, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spawning
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of freely releasing eggs and sperm into a body of water (fresh or marine); the physical act is known as spawning. The vast majority of aquatic and amphibious animals reproduce through spawning. These include the following groups: *Bony fishes *Crustaceans (such as crabs, shrimps, etc.) *Mollusks (such as oysters, octopus, squid) *Echinoderms (such as sea urchins, sea stars, sea cucumbers, etc.) *Amphibians (such as frogs, toads, salamanders, newts) *Aquatic insects (such as dragonflies, mayflies, mosquitoes) *Coral, which are living colonies of tiny, aquatic organisms—not plants, as they are sometimes perceived to be. Corals, while appearing sedentary or botanical by nature, actually spawn by releasing clouds of sperm and egg cells into the water column, where the two mix. As a general rule, aquatic or semiaquatic reptiles, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
