The pectoral fins of flying fish are particularly developed, and the long pectoral fins extend all the way to the tail. Flying fish can move at a high speed of 10 meter per second in the sea, and can also jump more than ten meters on the water. Flying fish have poor swimming ability. Floating in the middle of the sea during the day and falling to the bottom of the sea at night. Flying fish can take off at the speed of 18 meters per second, slide across the water surface at the speed of 16 kilometers per hour, stay in the air for more than 40 seconds, and the maximum flight distance exceeds 400 meters. Flying fish are rolling in the waves, approaching the blue sea, which is dizzying.
The maximum speed of swordfish is close to 1 12 km/h, and it is widely regarded as the fastest fish in the ocean. Coupled with a large dorsal fin similar to a sail, swordfish can have a slight advantage in versatility. Sails play an important role in regulating body temperature, but they are harmful in speed, because it is thought that these sails will increase the resistance of fish by as much as 18% when deployed. Fortunately, the sails can be folded and unfolded at will. By stretching the dorsal fin, swordfish can stop faster, so I put it above the fish speed.
The biggest difference between the flatfin swordfish and most swordfish is that the first fin on its back is sail-like and can extend from the top of its head to its tail. Flat fin. Of course, it also has the long sword-shaped mouth and streamlined body that most swordfish have, followed by the crescent shape and very thin pectoral fin of the flat-finned swordfish. The swordfish is bigger than other swordfish, usually 2-5 meters long, about the size of a ship. Swordfish is the top predator in subtropical waters, especially in the waters near islands and coasts, because of its huge size, fierce temperament and extremely fast swimming speed. Swordfish is a large carnivorous fish, which usually feeds on squid, saury and sea cucumber.
