Read the passage and answer the questions that follow.

Flying fish can be seen jumping out of warm ocean waters worldwide. Their streamlined torpedo shape helps them gather enough underwater speed to break the surface, and their large, wing-like pectoral fins get them airborne.
Flying fish are thought to have evolved this remarkable gliding ability to escape predators, of which they have many. Their hunters include mackerel, tuna, sword fish, marlin, and other larger fish. For their nutrition, flying fish feed on a variety of food, including plankton, bacteria and other tiny marine creatures. The average lifespan of flying fish is around five years in the wild. In size they can grow up to 18 inches.
There are about 40 known species of flying fish. Beyond their useful pectoral fins, all have unevenly forked tails, with the lower lobe longer than the upper lobe. Many species have enlarged pelvic fins as well and are known as four-winged flying fish.
The process of taking flight, or gliding, begins by gaining great velocity underwater, about 37 miles (60 kilometers) per hour. Angling upward, the four-winged flying fish breaks the surface and begins to taxi by rapidly beating its tail while it is still beneath the surface. It then takes to the air, sometimes reaching heights of over 4 feet (1.2 metres) and gliding long distances, up to 655 feet (200 metres). Once it nears the surface again, it can flap its tail and taxi without fully returning to the water. Capable of continuing its flight in such a manner, flying fish have been recorded stretching out their flights with consecutive glides spanning distances up to 1,312 feet (400 metres). Flying fish can soar high enough that sailors often find them on the decks of their ships.
Flying fish swim in large schools (groups) and are attracted to light, like a number of sea creatures, and fishermen take advantage of this with ample results. Canoes, filled with enough water to sustain fish, but not enough to allow them to propel themselves out, are affixed with a luring light at night to capture flying fish by the dozens. There is currently no protection status on these animals.
Sailors sometimes find flying fish on their ________.
