1. Swordfish

Swordfish, also known as Swordfish, is named for being the fastest swimmer in the ocean, and belongs to the genus Swordfish in the family Swordfish. Most swordfish weigh 60 to 120 kilograms and are about three meters long, with their mouths taking up a third of their length. Swordfish come in a variety of colors, with most having a tan back and body.

Swordfish have a smooth, sleek body with a small dorsal fin and no ventral fin or gills. But when the swordfish swims, its caudal shank can generate a lot of propulsion, so it can reach speeds of up to one hundred and thirty kilometers per hour.

The sailfish belongs to the genus Sailfish of the family Sailfish. Huge body, body length of about 2 to 5 meters, the body of the fish is mostly greenish-brown, body color is more colorful than the swordfish, but also the distribution of many white and gray dots. The same as the swordfish, its upper jaw like a sharp long sword. The difference is that its first dorsal fin is very large, even exceeding its body height. When it is at the surface with its first fin fully extended, it looks like a flying flag. Hence the name "sailfish".

Marlin is also called " marlin ", belongs to the marlin family marlin genus, also counted as a kind of sailfish. It has an elongated body and can be up to four meters long. The body is huge, the heaviest is more than 700 kilograms. The body color is mostly blue-gray, and the marlin does not have a large dorsal fin like the sailfish, but its first dorsal fin is high in the front like the swordfish, and long and short in the back. It is this large, ferocious marlin that is depicted in Ernest Hemingway's The Old Man and the Sea.
