Sailfish Size report

Sailfish (Istiophorus platypterus) is an oceanic pelagic and bony fish active in the tropics and subtropics, and there are two common types: oriental sailfish and gray sailfish. They are naturally ferocious, fast swimmers, and their speed reaches 90-110 miles per hour, making them one of the fastest swimming fish in the ocean. Sailfish are the top predators in the open ocean.

Swordfish are migratory fish with a slightly flattened, streamlined shape and well-developed muscles. They are top predators in the open ocean. The largest swordfish can be several meters long and weigh hundreds of kilograms.

Sailfish are widely distributed in the Atlantic, Indian, and Pacific oceans. Swordfish meat is tender and plump, and its muscles have different colors, including white, light red, bright red, etc. It has high nutritional value and is a high-grade fish food. Let's get more information about this marine.

Sailfish Size and Appearance

Sailfish are huge in shape, generally, more than two meters to five meters long, elongated, and slightly flattened. They are blue to gray with a white underbelly. The body is covered with fine scales, and there are grayish-white round spots on the blue-brown body. The upper jaw of the bill is like a long sharp spear, very prominent. The most obvious feature distinguishing a sailfish is the huge first dorsal fin on its back, which is even more than twice the body height, like a sail, hence the name sailfish.

When sailfish swim, they retract their high dorsal fins to reduce resistance; their sword-like snouts can quickly separate water; the forward thrust generated by constantly swinging the peduncle and caudal fins is like the propeller of a ship. With a streamlined body, well-developed muscles, and huge swinging power, sailfish can move forward as fast as an arrow off the string, with a maximum speed of 190 kilometers per hour and a normal speed of 90-110 kilometers per hour.

Average Size of Sailfish

  • Sailfish are considered the fastest fish in the sea.
  • These powerful, large fish can grow to more than 10 feet, about 6-11 ft, and weigh between 120-220 pounds.
  • Like other billfish, female sailfish can be larger than males, so they can carry as many eggs as possible and have a greater chance of successful reproduction in the open ocean.
  • Sailfish can live for 13 to 15 years.

Reproduce

It is easy to distinguish between male and female swordfish. The male sailfish in the mature reproductive stage has a bright body color, and the male fish in the estrus stage has scattered and uneven star stripes, while the female fish has a darker body color and a wide and plump abdomen. The ovulation of female fish lasts 6-7 days, and there are more than 10-20 grains per day. Males are extremely protective of their offspring.

Differences between Sailfish, Swordfish, and Marlin Fish

While both the sailfish and swordfish share the long beaks of billfish, swordfish can be much heavier, have flat bills, and are blue and silvery in color. And sailfish have their famous long dorsal fin, scales, teeth, and chromatophores that allow them to change color. The dorsal fin of a marlin also resembles a sail, but the fin is smaller than a sailfish's. Marlins have tubular, smooth bodies, unlike swordfish, has elongated, round bodies.

Final Words

Sailfish are usually found in warmer waters and are densely distributed in coastal and island-adjacent waters, forming schools of varying numbers. Sailfish usually work together, using their dorsal fins to create a barrier around their prey to feed on smaller schooling fish. Sailfish are fairly abundant throughout their range, and their population is considered stable. Their meat is fairly tough and not widely eaten, but they are prized as exciting game fish.
