Monsters ate a long, sharp sword that hunted fast ocean records

Atlantic sails (Istiophorus albicans), Istiophorus americanus, is a marine marine sail in the Istiophoridae family.This fish is 1.7m long and weighs up to 20kg, the length is up to 3.15m and the maximum weight is declared at 58.1 kg. They have the ability to swim water sprint short distances with speeds up to 111km / hour.

Sailfish have a 'prehistoric' appearance with fierce form. Image view of Atlantic sailfish Istiophorus albicans helps us relate to athletes competing in sailing. Because these fish have large dorsal fins lining the length of the body and when extended they look like sails. This large dorsal fin lets them abruptly stop or turn horizontally during fast swimming times. This sail is twice as tall as its height. Atlantic sails are metallic green with a long, pointed and pointed sail.

Tests in 1920 estimated that they were able to swim short sprints with speeds up to 111km per hour. They feed on the sea surface or at medium depth.

This fish lives in the Atlantic Ocean, can live to latitudes in warm temperate regions, it is found in the Atlantic Ocean and the Caribbean Sea, except for large areas of the central North Atlantic Ocean and South Atlantic Ocean, center from surface to depth of 200m.

Sailfish often roam throughout tropical and subtropical waters. Most of the time they live near the water. Usually, sailfish are solitary, but sometimes they swim together in small groups.

Thanks to such high speed, they easily catch up with prey (such as mackerel, herring, sardines, drumfish), and use their long beaks to knock their prey. When a certain fish is injured or dies from this fatal blow, the sail immediately turns back and quickly catches it. Occasionally, they rush themselves and crash into a herd of fish so fast and so strong that they also have to soar out of the water.

The food of the sailfish consists of many types of marine animals, it seems that they eat most fish and smaller squid than they meet on the street wandering for food.

Sailfish are quite clever, they know how to save effort when hunting. Occasionally, they coordinate with other sailors to hunt. They cornered the prey and chased the prey near the water, where the prey would find it difficult to find their way out. At this point, the sail alternately took turns eating, while the other sails were on duty to prevent the prey from escaping.

Sailfish lay eggs in the big sea, females lay eggs in the water, male fish also release semen into water - the eggs float along the ocean currents. Fish eggs hatch quite quickly: fertilized eggs will hatch out fry within just 1.5 days. Each spawning, a female sail can lay in water 4-5 million eggs, but most of these eggs cannot grow to adulthood. In return, young sailors grow very fast: young offspring within 1 year have reached about 1.2m in length, and the average life span of sailfish is about 10 years.
