Answer 1

Exocoetus is a genus of the flying fish, it is a bony fish and marine fish, it’s mouth is large and wide and bears the teeth within it and its body consists of cycloid scales. And they have fins, which help them to glide in the air.

Complete answer:
Flying fish consist of almost 40 species which belong to the family exocoetidae.
They are found worldwide, and mainly found in the warm water.
The special thing about these fish is they have the ability to fly, and this does not mean that they really fly, and they have the ability to jump, really they glide by flapping their wings.
Usually fish are small and they grow up to the maximum length of 45 centimeters.
They have wings like rigid fins, and they have an uneven forked tail.
Some of the species like Exocoetus Volitans contain two wings and have large extended pectoral fins.
Some other flying fish like California flying fish, they have four wings, and they have both the pectoral and pelvic fins which are enlarged.
The fish close the fins tightly to the streamline body, when they travel from the underwater swimming to the surface of the water.
When the fish reaches the surface it spreads the fins so it is able to balance the thrust and tail is lifted, and it is airborne and jumps on the water, up to some feet.

Note: They have the ability to glide, above the surface of water it is about 16km/hr. Some of the fliers can glide up to a span of 180 meters, in a single glide, within 43 seconds, they can glide up to 400 meters.
