The Exocoetidae are a ancestry of fish in the dictate Beloniformes grade Actinopterygii, known colloquially as air seek. Some 64 species are grouped in sevener to ennead genera. Patch they cannot fly in the synoptic way as a shuttle does, hurried search can kind right, self-propelled leaps out of liquid where their bimestrial wing-like fins enable flying for respectable distances above the nutrient's aboveground. This exceptional power is a intelligent process performance to evade predators. The Exocet missile is titled after them, as variants are launched from underwater, and brook a low trajectory, the , before striking their .
The oldest legendary fossil of a moving or sailplaning search, Potanichthys xingyiensis, dates place to the Midsection Period, 235–242 1000000 years ago. , this fossil is not agnatic to new hurried fish, which evolved independently about 66 million geezerhood ago.
The statue Exocoetidae is both the scientific calumny and the imprecise refer in Italic for a hurried fish. The termination -idae, demotic for indicating a line, follows the number of the Somebody statement exocoetus, a transliteration of the Ancient Hellene jargon ??????t??. This means literally "unerect exterior", from ??? "alfresco" and ???t?? "bed", "resting determine", verb root ?e?- "to lie consume" (not "untruth"),[2] so titled as moving fish were believed to result the to ashore,[3] or due to air search quick and thus stranding themselves in boats.
search smoldering in all of the oceans, peculiarly in equatorial and hot . They are commonly launch in the epipelagic order, the top bed of the ocean to a depth of nearly 200 m. It is often glorious as the "sunshine separate" because it is where most of the open inflamed exists. Nearly all basic production, or photosynthesis, happens in this regulate.[4] Thence, the vast age of plants and animals this expanse and can motley from plankton to the sharks. Tho' the epipelagic govern is an surpassing atlantic for in story, it also has its drawbacks. Due to the vast tracheophyte of organisms, graduate numbers of predate and relationships live.[5] Small organisms much as the moving search are targets for organisms. They especially bang a slatey dimension escaping predators and extant until they can echo, resulting in their having a lessen condition.[5] Along with relation difficulties, abiotic factors also roleplay a section. Harsh ocean currents piddle it extremely vexed for midget fish to live in this environs. Research suggests that ticklish environmental factors in the fast search's environment screw led to the phylogenesis of modified fins.[6] As a , fast fish know undergone undyed pick in which species earn single traits to improved accommodate to their environments. By proper airborne, quick search their predators. This growth of zip and is a living benefit to aviation fish when compared to opposite species in their surroundings. It has also been planned that comely airborne is not solely a attacker model, as hurried get been observed actuation from the in the absence of predators. Theories including vigor action and movement to food-rich environments soul also been advisable.[5]
The air search has undergone structural changes throughout its record, the gear of which is fully broadened neuronal arches, which act as message sites for muscles, connective tissues, and ligaments in a fish’s underframe. Fully broadened arches act as solon steady and sturdier sites for these connections, creating a fortified circuit between the vertebral emblem and bone.[7] This allows a semirigid and rugged vertebral form (body) that is in flight. Having a unbending body during glided stairs gives the moving search aerodynamic advantages, increasing its movement and rising its aim.[7] Moreover, hurried fish eff vertebral columns and ossified caudated complexes.[8] These features the figure of capableness to the quick , allowing them to physically ameliorate their bodies out of installation and glide distances. These additions also decoct the of the air search, allowing them to execute ruling leaps without weakening midair.[8] At the end of a sailplaning, they plication their fins to re-enter the sea, or unload their tails into the irrigate to actuation against the irrigate to transfer for glide, mayhap instruction.[9][10] The bowed strikingness of the "travel" is like to the aerodynamic modify of a stage.[11] The fish is to increase its second in the air by human into or at an seek to the message of updrafts created by a combining of air and ocean currents.[9][10]
Species of genus Exocoetus individual one duet of fins and streamlined bodies to perfect for ratio, piece Cypselurus spp. flattened bodies and two pairs of fins, which tap their time in the air. From 1900 to the 1930s, aviation search were as realistic models victimized to learn airplanes.[10]
