They are also found in the Mediterranean Sea. Swordfish make extensive migrations as the seasons change, and appear in Canadian waters from spring to fall, mostly in the Grand Banks of Newfoundland and the Scotian Shelf. Swordfish are large, robust fish distinguished by their very long, pointed snout, from which they take their name. Aside from this feature, they generally resemble other species of tuna. They have a thick body that tapers considerably towards their tail fin, which is long and slender.
On their back side is a large, curved dorsal fin close to their head, with two thin pectoral fins opposite it. Swordfishes commonly grow 3 meters 10 feet in length.
Although, the largest swordfish was found to have a length of 4. Swordfish have a special organ in front of their eyes, which is also found in some species of sharks.
This organ helps them to warm up their eyes and brain in cold waters. Swordfish feed on a wide variety of smaller and larger fishes. They can eat smaller fishes as a whole, but for larger fishes, they use their sharp bill to attack them. They can also eat octopuses and squids as their food source. Swordfish eat on daily basis, mostly at night times. They normally come to the surface in search of smaller fishes. Another characteristic of swordfish is that it is an animal ectothermic , that is, capable of maintaining the temperature of your body at a higher range than that of the water in which it is found.
Finally, mention that they are fish with a great vision and as a general rule, loners. Having a weapon as powerful as its sharp and pointed mouth, presages that swordfish habits are rather carnivorous.
If you think that, you are correct. They are one of the fish with the best hunting skills in the world. What's more, it no longer only depends on that weapon that we place so much emphasis on, but speed and agility in its movements it provides it with a much greater predatory potential. Among the wide range of species that we could classify as potential swordfish prey are other fish such as mackerel, hake, tuna, etc.
To them we can also add some crustaceans, cephalopods, etc. Swordfish are animals oviparous , which translates into hatching from eggs. The fertilization process takes place through the external fertilization method The females release the eggs into the water, which will later be fertilized by the male's semen , and it is noteworthy that the males reach sexual maturity earlier than the females. Egg spawning takes place throughout the year Therefore, swordfish do not have a specific time to reproduce, as long as the waters have a rather temperate temperature.
The chosen areas are usually the Caribbean seas, Florida coasts and the Gulf of Mexico. Another fact, more than curious, is that females are capable of storing nothing more and nothing less than 1 to 29 million eggs. It is true that for the size of these fish, the eggs are very small, never larger than 2 millimeters in diameter. We hope we have introduced you to a little more about swordfish, which is unfortunately in decline due in large part to the indiscriminate fishing Since it is one of the species, it has a great presence in human nutrition.
