Beloniformes
Beloniformes is an order composed of six families (and about 264 species) of freshwater and marine ray-finned fish: * Adrianichthyidae (ricefish and medakas) * Belonidae (needlefish) * Exocoetidae (flyingfishes) * Hemiramphidae (halfbeaks) * Scomberesocidae (sauries) * Zenarchopteridae (viviparous halfbeaks) With the exception of the Adrianichthyidae, these are streamlined, medium-sized fishes that live close to the surface of the water, feeding on algae, plankton, or smaller animals including other fishes. Most are marine, though a few needlefish and halfbeaks inhabit brackish and fresh waters. The order is sometimes divided up into two suborders, the Adrianichthyoidei and the Belonoidei, although this clade is referred to as Exocoetoidei in the 5th edition of ''Fishes of the World''. The Adrianichthyoidei contain only a single family, the Adrianichthyidae. Originally, the Adrianichthyidae were included in the Cyprinodontiformes and assumed to be closely related to the ...

Adrianichthyoidei
The ricefishes are a family (Adrianichthyidae) of small ray-finned fish that are found in fresh and brackish waters from India to Japan and out into the Malay Archipelago, most notably Sulawesi (where the Lake Poso and Lore Lindu species are known as buntingi). The common name ricefish derives from the fact that some species are found in rice paddies. This family consists of about 37 species in two genera (some recognize a third, '' Xenopoecilus''). Several species are rare and threatened, and some 2–4 may already be extinct. Description Most of these species are quite small, making them of interest for aquaria. ''Adrianichthys'' reach lengths of depending on the exact species involved, while the largest ''Oryzias'' reaches up to . Most ''Oryzias'' species are less than a half this length, with the smallest being up to only long. They have a number of distinctive features, including an unusual structure to the jaw, and the presence of an additional bone in the tail. ...

Belonidae
Needlefish (family Belonidae) or long toms are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., ''Strongylura''), while a few genera are confined to freshwater rivers and streams, including '' Belonion'', ''Potamorrhaphis'', and ''Xenentodon''. Needlefish closely resemble North American freshwater gars (family Lepisosteidae) in being elongated and having long, narrow jaws filled with sharp teeth, and some species of needlefishes are referred to as gars or garfish despite being only distantly related to the true gars. In fact, the name "garfish" was originally used for the needlefish ''Belone belone'' in Europe and only later applied to the North American fishes by European settlers during the 18th century. Description Needlefish are slender, ranging from in length. They have a single dorsal fin, placed far back on the body, almost op ...

Exocoetoidea
Exocoetoidea is a superfamily of fishes that comprises three families, the flying fishes, the halfbeaks and the viviparous halfbeaks. They are found in tropical and subtropical waters around the world. Exocoetoidea is part of the suborder Exocoetoidei of the order Beloniformes. Characteristics The fishes have large scales, with normally 38–60 scales along the lateral line. They have a small mouth and some have an elongated lower jaw (but not an elongated upper jaw). They do not have the isolated finlets between the dorsal fin and anal fin and the caudal fin. The dorsal and anal fins typically have 8–18 rays each but there are as many as 25 in '' Euleptorhamphus''. The third pair of upper pharyngeal bones are united, but not fused, to form a palate. Families The three families included in this superfamily are: * Family Exocoetidae Risso, 1827 (flying fishes) * Family Hemiramphidae Hemiramphidae is a family of fishes that are commonly called halfbeaks, spipe fis ...

Exocoetidae
The Exocoetidae are a family of marine fish in the order Beloniformes class Actinopterygii, known colloquially as flying fish or flying cod. About 64 species are grouped in seven to nine genera. While they cannot fly in the same way a bird does, flying fish can make powerful, self-propelled leaps out of the water where their long wing-like fins enable gliding for considerable distances above the water's surface. The main reason for this behavior is thought to be to escape from underwater predators, which include swordfish, mackerel, tuna, and marlin, among others, though their periods of flight expose them to attack by avian predators such as frigate birds. Barbados is known as "the land of the flying fish", and the fish is one of the national symbols of the country. The Exocet missile is named after them, as variants are launched from underwater, and take a low trajectory, skimming the surface, before striking their targets.

Zenarchopteridae
Zenarchopteridae, the viviparous halfbeaks, is a family in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous (the family also includes oviparous species).Berra, T.M. (2001). ''Freshwater Fish Distribution.'' p. 320. Tan, H.H. & Lim, K.K.P. (2013). Three new species of freshwater halfbeaks (Teleostei: Zenarchopteridae: ''Hemirhamphodon'') from Borneo.' The Raffles Bulletin of Zoology 61(2): 735–747. The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus ''Zenarchopterus'' also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded aquarium fish. Genera The following genera are classified within the family Zenarchopteridae * ''Dermogenys'' Kuhl & van Hasselt, 1823 * ''Hemirhamphodon'' Bleeker, 1865 * '' Nomorhamphus'' Weber & de Beaufort ...

Hemiramphidae
Hemiramphidae is a family of fishes that are commonly called halfbeaks, spipe fish or spipefish. They are a geographically widespread and numerically abundant family of epipelagic fish inhabiting warm waters around the world. The halfbeaks are named for their distinctive jaws, in which the lower jaws are significantly longer than the upper jaws. The similar viviparous halfbeaks (family Zenarchopteridae) have often been included in this family. Though not commercially important themselves, these forage fish support artisanal fisheries and local markets worldwide. They are also fed upon by other commercially important predatory fishes, such as billfishes, mackerels, and sharks. Taxonomy In 1758, Carl Linnaeus was the first to scientifically describe a halfbeak, ''Esox brasiliensis'' (now ''Hemiramphus brasiliensis''). In 1775 Peter Forsskål described two more species as ''Esox'', '' Esox far'' and '' Esox marginatus''. It was not until 1816 that Georges Cuvier created the gen ...

Scomberesocidae
Sauries are fish of the family Scomberesocidae. There are two genera, each containing two species. The name Scomberesocidae is derived from the ''scomber'', which in turn is derived from the Greek ''skombros'', meaning "mackerel", and the Latin ''esox'' meaning pike. Sauries are marine epipelagic fish which live in tropical and temperate waters. These fish often jump while swimming near the surface, skimming the water, which is similar to flying fish, a fellow member of the order beloniformes. The jaws of sauries are beak-like, ranging from long, slender beaks to relatively short ones with the lower jaw only slightly elongated. The mouth openings of sauries, however, are small and the jaws have weak teeth. The most distinctive feature of sauries, however, is the presence of a row of small finlets behind the dorsal and anal fins. They also lack swim bladders. Sauries grow to a maximum length of about , but the group also includes the smallest of all epipelagic fish, ''Cololabis ad ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.
