Swordfish is a kind of fish that lives in the ocean, and their distribution range is very wide. In terms of classification, swordfish belong to Osteichthyes, Perciformes and Swordfish Family. They belong to a kind of bony fish. From the point of view of distribution depth, swordfish is mainly distributed in the deeper part of the ocean, specifically in the depth range of 200-600 meters, and a small part of it is distributed in the depth of 650 meters, which can be said to be a kind of deep-water fish. They have adapted to the deep environment of the sea, that is, the environment with high pressure and salinity.
In terms of size, the swordfish is a large fish. Their average weight can reach 68-113 kilograms, and their average length can reach 2.1 meters. At present, the largest recorded swordfish is 4.5 meters in length and weighs about 650 kilograms. Females, by contrast, are larger. Researchers have studied swordfish in the Pacific Ocean and found that their average length is nearly two meters.
As mentioned above, the swordfish belongs to a kind of fish that lives in the ocean. Therefore, from the point of view of their living environment, they belong to the marine fish. Their habits and characteristics are very different from those of the freshwater fish. Moreover, the distribution of swordfish in the global scope is very extensive, in the Indian Ocean, the Atlantic Ocean and the Pacific Ocean. In these three oceans, swordfish are mainly distributed in low latitudes near the equator, because swordfish like to live in warm water. That is to say, they are more widely distributed in tropical and subtropical regions. Because of the high latitude and low water temperature in the Arctic Ocean, there is basically no distribution of swordfish.
