Big flying fish

Postby Maumuro В» 24.01.2020

.

Most aquatic animals do not rely upon the cornea for refraction; in fact some do not even have a cornea. Evolutionarily, the cornea probably appeared early in vertebrate phylogeny although not for refraction. Rather, the cornea probably first appeared for protection, especially for the crystalline lens. Early fish developed a thin protective layer, and some species subsequently developed a second layer of cornea called the spectacle. In many fish neither layer of cornea is especially good optically, but they do not have to be.

Parenthetically, echoes of those two separate layers still exist in our own cornea. Neither of these two corneal layers has to be particularly smooth, because when the cornea is immersed in water, there is almost no refraction obtained from the cornea, permitting light to pass through unchanged. This creates a problem for any fish that must navigate the aerial world in any meaningful visual manner. What do such creatures do to overcome the generally poor visual characteristics of the lacklustre piscine cornea?.

Conceptually, flying fish seem curious to us but these winged creatures simply occupy an unusual niche. Found in most oceans, flying fish seem to be concentrated in the Atlantic Ocean and the Caribbean Sea, although the largest species cover illustration is found in the Pacific.

This fascinating creature feeds in the neustonic zone of the ocean surface waters , and although this zone is very rich with plankton it is also very dangerous. Predators can use the sky as a backlight and patrol beneath the surface of the water looking for prey. Hence, a neustonic fish must be primed to make a hasty escape.

To escape, flying fish have chosen to fly. The flying fish, then, must be prepared to navigate epipelagic waters as well as the aerial world above them. Just like many other animals, including some frogs, snakes, mammals and reptiles, the flying fish does actually become airborne for significant distances using pectoral fins as wings for gliding. Cypselurus californicus will obtain the necessary speed by sculling with its pelvic fin, vaulting itself skyward but flying close to the water's surface.

The fish rapidly moves the lower lobe of its tail to propel itself forward once the rest of the body has already left the water. Eventually, even the tail leaves the water and the fish is airborne. This remarkable feat can be done by making a series of glides. When the fish is airborne, it will descend towards the surface.

Instead of dropping entirely into the water, the fish can simply dip its tail into the water to produce forward thrust. The various genera of flying fish have a spectrum of flight capability that can be quantified based on wing area to body mass ratio and it probably correlates with visual capability out of water.

To do this, the flying fish has evolved a pyramidal cornea with an apex at its centre. Its function remains a mystery. The lens of the flying fish eye is piscine—large and round with a high index of refraction. As a result, the cornea does not have to be highly refractive out of water and is relatively flat.

The fish has been documented to be emmetropic in air and only mildly hyperopic in water. It is unknown if the measurements in water were in an accommodated state. Essentially, the cornea extends almost to the equator of the globe. Certainly, few animals would proceed in any medium without the sensory mechanism to interpret its surroundings, especially if moving with any speed.
